Current is provided through a universal power supply 80 ... 230 V AC, 45 ... 65 Hz /
24 ... 60 V DC. The analyzer provides two 0 (4) .... 20 mA current outputs for transmission of measured value and temperature, for example. Four floating relay contacts
are available for free configuration. A PID controller and a time-controlled cleaning
function can be configured. Two parameter sets are provided. You can externally
switch between them via the Control input, for example. The HOLD input allows
setting the HOLD mode from the outside. The analyzer also provides power supply
and allows signal processing for additional transmitters, e.g., for flow monitoring.
You can select one of the following measuring functions:
• pH
• ORP
• Oxygen
• Oxygen, optical
• Conductivity measurement (conductive/inductive)
• Dual conductivity measurement using two analog sensors
• Dual measurement of pH/pH and pH/Oxy using two Memosens sensors

23Selecting the Measuring Function
Start-Up
Upon initial start-up, the analyzer automatically recognizes a connected module and
adjusts the software correspondingly. When you replace the measuring module, you
must select the corresponding measuring function in the “Service” menu.
This does not apply to the multi-channel module for dual conductivity measurement
and to the connection of Memosens sensors. Here, you will be prompted to select
the desired measuring function upon first start-up.
Changing the Measuring Function
In the “Service” menu you can select another measuring function at any time.
24 Inserting a Module
Measuring modules for connection of analog pH sensors:
The measuring module for the connection of analog pH sensors is simply inserted
into the module slot. Upon initial start-up, the analyzer automatically recognizes the
module and adjusts the software correspondingly. When you replace the measuring module, you must select the corresponding measuring function in the “Service”
menu.
Measuring module for 2nd Memosens channel
If you want to measure two process variables using Memosens sensors, you must
insert a Memosens module for the second channel. The operating mode for
multi-channel measurement (“device type”) must be selected in the configuration
menu.
The following combinations are possible:
Memosens pH + Memosens pH
Memosens pH + Memosens Oxy

Calibration and Maintenance in the Lab
The “MemoSuite” software allows calibrating Memosens sensors under reproducible
conditions at a PC in the lab. The sensor parameters are registered in a database.
Documenting and archiving meet the demands of FDA CFR 21 Part 11. Detailed
reports can be output as csv export for Excel. MemoSuite is available as accessory
and comes in the versions “Basic” and “Advanced”: www.knick.de.

Display of calibration data, display of sensor data, sensor monitor, performing a
device self-test, viewing the logbook entries, display of hardware/software versions
of the individual components. The logbook can store 100 events (00...99). They can
be displayed directly on the device. The logbook can be extended to 200 entries
using a TAN (Option).
HOLD
Manual activation of HOLD mode, e.g., for replacing a sensor. The signal outputs
adopt a defined state.
Calibration
Every sensor has typical characteristic values, which change in the course of the
operating time. Calibration is required to supply a correct measured value. The
device checks which value the sensor delivers when measuring in a known solution.
When there is a deviation, the device can be “adjusted“. In that case, the device displays the “actual“ value and internally corrects the measurement error of the sensor.
Calibration must be repeated at regular intervals. The time between the calibration
cycles depends on the load on the sensor. During calibration the device is in HOLD
mode.
During calibration the device remains in the HOLD mode until it is stopped by the
operator.
Configuration
You must configure the analyzer for the respective measurement task. In the “Configuration“ mode you select the adjusted measuring function, the connected sensor,
the measuring range to be transmitted, and the conditions for warning and alarm
messages. During configuration the device is in HOLD mode.
Configuration mode is automatically exited 20 minutes after the last keystroke.
The device returns to measuring mode.
Service
Maintenance functions (current source, relay test, controller test), passcode assignment, device type selection, reset to factory settings, enabling of options (TAN).
47HOLD Mode
The HOLD mode is a safety state during configuration and calibration.
Output current is frozen (LAST) or set to a fixed value (FIX).
Alarm and limit contacts are disabled.
The display backlighting turns orange, display icon:
Terminating the HOLD mode
The HOLD mode is exited by switching to measuring mode (hold meas key
depressed). The display reads “Good Bye“. After that, the HOLD mode is exited.
When the calibration mode is exited, a confirmation prompt ensures that the
installation is ready for operation (e.g.: sensor reinstalled, located in process).

• LAST: The output current is frozen at its last value. Recommended for short
configuration procedures. The process should not change decisively during
configuration. Changes are not noticed with this setting!
• Fix: The output current is set to a value that is noticeably different from the
process value to signal the control system that the device is being worked at.
HOLD inactive 0...2 V AC/DC
HOLD active 10...30 V AC/DC
External activation of HOLD
The HOLD mode can be activated from outside by sending a signal to the HOLD
input (e.g., from the process control system).
48
Alarm
When an error has occurred, Err xx is displayed immediately.
Only after expiry of a user-defined delay time will the alarm be registered and
entered in the logbook.
During an alarm the display blinks, the display backlighting turns red.
Error messages can also be signaled by a 22 mA output current (when configured
correspondingly).
The alarm contact is activated by alarm or power failure. 2 sec after the failure event
is corrected, the alarm status will be deleted.
The 22-mA signal can also be triggered by Sensoface messages (configurable).
Generating a message via the CONTROL input
(min. flow / max. flow)
The CONTROL input can be used for parameter set selection or for flow measurement (pulse principle), depending on its assignment in the “Configuration” menu.
First, the flow transmitter must be calibrated in the CONTROL menu: ADJUST FLOW
When preset to flow measurement
an alarm can be generated when the measured flow exceeds a specified range:

Sensor Verification (TAG, GROUP)
When Memosens sensors are calibrated in the lab, it is often useful and sometimes even mandatory that
these sensors will be operated again at the same measuring points or at a defined group of measuring
points. To ensure this, you can save the respective measuring point (TAG) or group of measuring points
(GROUP) in the sensor. TAG and GROUP can be specified by the calibration tool or automatically entered
by the transmitter. When connecting an MS sensor to the transmitter, it can be checked if the sensor
contains the correct TAG or belongs to the correct GROUP. If not, a message will be generated, Sensoface
gets “sad”, and the display backlighting turns magenta (purple). The “sad” Sensoface icon can also be signaled by a 22 mA error current. Sensor verification can be switched on in the Configuration in two steps
as TAG and GROUP if required.
When no measuring point or group of measuring points is saved in the sensor, e.g., when using a new
sensor, Stratos enters its own TAG and GROUP. When sensor verification is switched off, Stratos always
enters its own measuring point and group. A possibly existing TAG/GROUP will be overwritten.
57
Support of Pfaudler Sensors
or pH sensors with a zero point other than pH 7 and/or deviating slope,
e.g., pH sensors with a zero point at pH 4.6
This requires an additional function (TAN).
The option is enabled in the SERVICE / OPT: PFAUDLER menu.
For Pfaudler standard pH sensors, you can specify a nominal zero point and a nominal slope.
In addition, you can enter a pHiso value.
The additional entries appear in the CONFIGURATION / SENSOR menu:
SNS: NOM ZERO (default: 07.00 pH)
SNS: NOM SLOPE (default: 59.2 mV)
SNS: PH_ISO (default: 07.00 pH)
Prior to measurement, you must enter the values for nominal zero and slope and the isothermal intersection point pHiso as provided by the manufacturer and perform a calibration using
suitable buffer solutions.
When you use a Memosens Pfaudler sensor, the data will be read from the sensor or will be set
to standard values. Here, you do not have to make entries. The respective menu items will be
suppressed.
The nominal ZERO/SLOPE values are required for the proper functioning of the sensor monitoring and calibration functions (Sensoface, Calimatic), they do not replace an adjustment
(calibration)!

Adaptive Cal Timer (ACT)
By issuing a Sensoface message, the adaptive calibration timer reminds you to
calibrate the sensor. After expiration of the interval, Sensoface is getting “sad”.
Pressing the info key shows the text “OUT OF CAL TIME CALIBRATE SENSOR” which
reminds you that a calibration is due. The ACT interval is either read automatically
from the sensor settings or can be specified manually (max. 9999 days).
Stressing influences (temperature, measurement in extreme ranges) shorten the
timer interval.
The adaptive cal timer is reset after each calibration.
You can configure the current outputs so that a Sensoface message generates a
22-mA error signal, see page 91.

Sensor Verification (TAG, GROUP)
When Memosens sensors are calibrated in the lab, it is often useful and sometimes even mandatory that
these sensors will be operated again at the same measuring points or at a defined group of measuring
points. To ensure this, you can save the respective measuring point (TAG) or group of measuring points
(GROUP) in the sensor. TAG and GROUP can be specified by the calibration tool or automatically entered
by the transmitter. When connecting an MS sensor to the transmitter, it can be checked if the sensor
contains the correct TAG or belongs to the correct GROUP. If not, a message will be generated, Sensoface
gets “sad”, and the display backlighting turns magenta (purple). The “sad” Sensoface icon can also be signaled by a 22 mA error current. Sensor verification can be switched on in the Configuration in two steps
as TAG and GROUP if required.
When no measuring point or group of measuring points is saved in the sensor, e.g., when using a new
sensor, Stratos enters its own TAG and GROUP. When sensor verification is switched off, Stratos always
enters its own measuring point and group. A possibly existing TAG/GROUP will be overwritten.

Time averaging filter
To smoothen the current output, a low-pass filter with adjustable filter time constant
can be switched on. When there is a jump at the input (100 %), the output level is
at 63 % after the time interval has been reached. The time interval can be set from
0 to 120 sec. If the time interval is set to 0 sec, the current output directly follows the
input.
Note:
The filter only acts on the current output, not on the display, the limit values, or the
controller!
During HOLD the filter is not applied. This prevents a jump at the output.

Protective Wiring of Relay Contacts
Relay contacts are subject to electrical erosion. Especially with inductive and capacitive loads, the service life of the contacts will be reduced. For suppression of sparks
and arcing, components such as RC combinations, nonlinear resistors, series resistors
and diodes should be used.

121Sensor Verification (Memosens)
Time and Date
Control of the calibration and cleaning cycles is based on the time and date of the integrated real-time
clock.
In measuring mode the time is shown in the lower display. When using digital sensors, the calibration
data is written in the sensor head. In addition, the logbook entries (cf Diagnostics) are provided with a
time stamp.
Note:
There is no automatic switchover from winter to summer time!
Be sure to manually adjust the time!
Sensor Verification (TAG, GROUP)
When Memosens sensors are calibrated in the lab, it is often useful and sometimes even mandatory that
these sensors will be operated again at the same measuring points or at a defined group of measuring
points. To ensure this, you can save the respective measuring point (TAG) or group of measuring points
(GROUP) in the sensor. TAG and GROUP can be specified by the calibration tool or automatically entered
by the transmitter. When connecting an MS sensor to the transmitter, it can be checked if the sensor
contains the correct TAG or belongs to the correct GROUP. If not, a message will be generated, Sensoface
gets “sad”, and the display backlighting turns magenta (purple). The “sad” Sensoface icon can also be signaled by a 22 mA error current. Sensor verification can be switched on in the Configuration in two steps
as TAG and GROUP if required.
When no measuring point or group of measuring points is saved in the sensor, e.g., when using a new
sensor, Stratos enters its own TAG and GROUP. When sensor verification is switched off, Stratos always
enters its own measuring point and group. A possibly existing TAG/GROUP will be overwritten.

Note:
• All calibration procedures must be performed by trained personnel. Incorrectly
set parameters may go unnoticed, but change the measuring properties.
• The response time of the sensor and temperature probe is considerably reduced
when the sensor is first moved about in the buffer solution and then held still.
The device can only operate properly when the buffer solutions used correspond to
the configured set. Other buffer solutions, even those with the same nominal values,
may demonstrate a different temperature response.
This leads to measurement errors.
When using ISFET sensors or sensors with a zero point other than pH 7, the
nominal zero point must be adjusted each time a new sensor is connected. This is
important if you want to obtain reliable Sensoface messages. The Sensoface messages issued during all further calibrations are based on this basic calibration.

Calibration is used to adapt the device to the individual sensor characteristics,
namely asymmetry potential and slope.
Access to calibration can be protected with a passcode (SERVICE menu).

132 ORP (Redox) Calibration
The potential of a redox sensor is calibrated using a redox (ORP) buffer solution.
In the course of that, the difference between the measured potential and the potential of the calibration solution is determined according to the following equation.
During measurement this difference is added to the measured potential.
= displayed ORP
= direct sensor potential
= delta value, determined during calibration
The sensor potential can also be related to another reference system – e.g., the
standard hydrogen electrode. In that case the temperature-corrected potential (see
table) of the reference electrode used must be entered during calibration. During
measurement, this value is then added to the ORP measured.
Please make sure that measurement and calibration temperature are the same since
the temperature behavior of the reference electrode is not automatically taken into
account.

134 Product Calibration
Calibration by sampling (one-point calibration).
During product calibration the sensor remains in the process.
The measurement process is only interrupted briefly.
Procedure:
1) The sample is measured in the lab or directly on the site using a portable meter.
To ensure an exact calibration, the sample temperature must correspond to the
measured process temperature.
During sampling the device saves the currently measured value and then returns
to measuring mode. The “calibration“ mode indicator blinks.
2) In the second step you enter the measured sample value in the device. From the
difference between the stored measured value and entered sample value, the
device calculates the new asymmetry potential.
If the sample is invalid, you can take over the value stored during sampling. In that
case, the old calibration values are stored. Afterwards, you can start a new product
calibration.

Sensocheck, Sensoface Sensor Monitoring
Sensocheck continuously monitors the sensor and its wiring.
The three Sensoface indicators provide information on required
maintenance of the sensor. Additional icons refer to the error cause.
Pressing the info key shows an information text.
Note:
The worsening of a Sensoface criterion leads to the devaluation of the Sensoface
indicator (Smiley gets “sad”). An improvement of the Sensoface indicator can only
take place after calibration or removal of the sensor defect.
Sensoface message
The Sensocheck message is also output as error message Err 15. The alarm contact is
active, the display backlighting turns red (when configured correspondingly).
Sensoface can be output as a 22-mA signal via the current outputs.
Disabling Sensocheck and Sensoface
Sensocheck can be switched off in the configuration menu (then Sensoface is also
disabled).
Exception:
After a calibration, a smiley is always displayed for confirmation.

Note:
The actual pH values of the individual batches of the reference materials are documented in a certificate of an accredited laboratory. This certificate is supplied with
the respective buffers. Only these pH(S) values shall be used as standard values for
the secondary reference buffer materials. Correspondingly, this standard does not
include a table with standard pH values for practical use. The table above only provides examples of pH(PS) values for orientation.

175-U1- Specifiable Buffer Set
You can specify a buffer set with 2 buffer solutions in the temperature range of
0 ... 95 °C, step width: 5 °C.
To do so, select buffer set -U1- in the configuration menu.
As delivered, the Ingold technical buffer solutions pH 4.01 / 7.00 are stored as buffer
set and can be edited.
Conditions for the specifiable buffer set:
• All values must lie in the range pH 0 ... 14.
• Maximum difference between two adjacent pH values
(5 °C step width) of the same buffer solution: pH 0.25
• The values of buffer solution 1 must be lower than those of
buffer solution 2:
The difference between values for identical temperatures must be greater than
2 pH units.
Faulty entries are indicated in measuring mode by the
“FAIL BUFFERSET -U1-“ message.
The 25 °C value is always used for buffer display during calibration.
