6.2 Sensor ID/SN
1. Enter Sensor ID/SN
An alphanumeric sensor ID with up to 12 characters can be entered. The sensor ID will be assigned to
each calibration and measurement value. This is valuable for tracing back data.
The maximium number of sensors is 30. When this number has been reached, first a sensor has to
be deleted before a new sensor can be created (see the note at the end of this section how to delete a
sensor).
If a new sensor ID is entered, the theoretical calibration slope and offset for this type of electrode will
be loaded. The sensor has to be newly calibrated.
If a sensor ID is entered, which is already in the memory of the meter and has been calibrated before,
the specific calibration data for this sensor ID will be loaded.
When connecting an ISM
●
Automatically recognize the sensor when it's turned on (alternatively, when pressing READ or
CAL)
●
Load the stored sensor ID, sensor SN and sensor type as well as the latest calibration data of this
sensor
●
Use this calibration for the subsequent measurements

2. Select Sensor ID
Already entered sensor IDs can be selected from a list.
If a sensor ID is selected, which is already in the memory of the meter and has been calibrated before,
the specific calibration data for this sensor ID will be loaded.
Note
●
You can delete a sensor ID with its calibrations in the calibration data menu.
