CIP/SIP Counters
Note:
CIP/SIP counters are available for the following pH sensor types:
SIP counter: Memosens pH, Memosens pH/ORP; CIP counter: Memosens pH/ORP
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 2 hours after the start to ensure that the cycle
is complete.
Note:
With Memosens sensors, an entry is also made in the sensor.
5.7.2 Calibration Presettings
The calibration presettings can be defined in the parameter settings or adjusted directly in the Calibra-
tion menu prior to the calibration.
Calibration mode
: Presetting of calibration mode, e.g., Calimatic, manual, product calibration, data en-
try, temperature
If Calimatic automatic calibration is selected, the buffer set to be used must also be selected.
Calibration points
: Selection of how many calibration points are to be used in the calibration
Drift check
: Sets the sensitivity of the drift check (fine, standard, coarse)

Calibration Timer
When a preset calibration interval expires, the calibration timer generates a message text to indicate
the need for calibration. If “Auto” is selected, the interval is set to 168 h. If “Individual” is selected, you
can select a custom interval.
