6.1 Special features for measurement with digital sensors
with Memosens technology
!
Note!
Digital sensors with Memosens technology can only be used in combination with the appropriate
Topclean S version (CPC30-xx5xxxxxxx).
You can retrofit an existing Topclean S for Memosens technology (see page 134).
Commissioning
Digital sensors with Memosens technology save calibration data. Therefore, commissioning of these
sensors differs from the commissioning of standard electrodes. Proceed as follows:
1. Install the transmitter and the assembly.
2. Connect the transmitter and the sensor cable.
3. Configure the transmitter according to your specific requirements (see »Description of
functions« on page 56).
4. Connect the factory-calibrated sensor with Memosens technology and immerse it in the
medium or buffer.
5. The saved sensor-specific calibration data are automatically transferred to the transmitter.
6. The measured value is displayed.
Data storage
Digital sensors are able to store the following data:
• Manufacturing data
– Serial number
– Order code
– Date of manufacture
• Calibration data
– Calibration date
– Calibrated slope at 25 °C / 77 °F
– Calibrated zero point at 25 °C / 77 °F
– Temperature offset
– Serial number of the transmitter used for the last sensor calibration
– Buffer values of the last calibration
– Change in slope compared to preceding calibration
– Change in zero point compared to preceding calibration
• Application data
– Temperature application range
– pH application range
– Operating hours at temperatures above 80 °C / 176 °F and 100 °C / 212 °F
– Operating hours at very low and very high pH values (Nernst voltage below -300 mV,
above +300 mV)
– Number of sterilisations
