05. In the Message menu item, select whether and how an exceeded limit is to be displayed:
Off No message.
Failure
A failure message is shown in off-limit conditions; the corresponding NAMUR icon is displayed.
Maintenance A maintenance required message is shown in off-limit conditions; the corresponding NAMUR icon
is displayed.
06. Set the sensor monitoring details for further sensor data, e.g., Sensocheck, sensor operating time,
or CIP/SIP counter.
07. Using the left softkey: Back, confirm the sensor monitoring settings and adjust further parameters.
or
Using the right softkey: Back to Meas.
, confirm the sensor monitoring settings and end the func-
tion check (HOLD).
CIP/SIP Counters
Note: This function is not available for all sensor types.
CIP/SIP cycles are used to clean or sterilize process-wetted parts in the process. Depending on the ap-
plication, either one chemical (alkaline solution, water) or several chemicals (alkaline solution, water,
acidic solution, water) are used.
• CIP temperature > 55°C/131°F
• SIP temperature > 115°C/239°F
The cleaning (cleaning in place) and sterilization (sterilization in place) cycles are counted to measure
the load on the sensor, e.g., in biotechnology applications.
Note: If measurements are generally taken at high temperatures (> 55°C/131°F), the counters should
be switched off.
When a CIP/SIP counter is switched on, a maximum number of cycles can be entered. As soon as the
counter has reached the specified value, a maintenance required message is triggered and the NAMUR
icon
is displayed.
Note: A CIP or SIP cycle is only entered into the logbook 2hours after the start to ensure that the cycle
is complete.
Note: With Memosens sensors, an entry is also made in the sensor.

5.10.2 Calibration Presettings
The calibration presettings can be defined in the parameter settings or adjusted directly in the
Calibration menu prior to the calibration.
Calibration mode: Presetting of calibration mode, e.g., automatic, manual, product calibration, zero
point, installation factor, data entry, temperature
Further options are available depending on the calibration mode.
Automatic:
• Select calibration solution (NaCl/KCl)
Product calibration:
• Product calibration with/without temperature compensation
