Note
Every measurement can be endpointed manually by pressing Read. The meter then displays
The table below shows how the endpoint format is displayed in the course of the measurement.
Preselected format
Auto endpoint
Manual endpoint
Timed endpoint
The endpoint format actually used (last column) and not that preselected is stored with the data.

Sensor ID
You can set an 8-digit, numerical sensor ID. In the GLP mode, the sensor ID will be assigned to each calibra-
tion and measurement value. This allows you to trace back data.
Set cal.
Buffer
In pH mode you can choose one of 6 different predefined buffer groups. You can also define your own buffer
group (up to 5 buffers).
In the ion mode, you can define temperature, units and concentrations for up to 5 ion standards. For more
details, see Section 4.4.
Note
When using a user-defined buffer group in the calibration, the screen will display the buffer value you set.
Make sure that you use the correct buffer. You should also keep the buffer temperature at the set value. When
using a temperature probe, if the temperature measured differs by more than 0.5 °C from the set value, an
error message is shown.
Calibration Reminder
If you choose calibration reminder "ON", you are reminded to perform a new calibration after a certain user
defined interval (maximum 9999 h) has elapsed. In this case blinks.
Calibration mode
If high pH accuracy is required, the segment method is recommended. The calibration curve is made up of
linear segments joining the individual calibration points.
With the linear method, the calibration curve is determined using linear regression. This method is recom-
mended for samples with widely varying pH values.
