6.1.2 Calibration interval

The calibration evaluation is displayed as a sensor symbol.
The sensor symbol flashes after the adjusted calibration interval has expired. It
is still possible to measure.
To ensure the high measuring accuracy of the meter, calibrate after
the calibration interval has expired.
The calibration interval is set to 150 days in the factory.
You can change the interval (1 ... 999 days):
1. Open the menu for measurement settings with [Menu]<F1>.
2. In the Calibration / Calibration interval menu, set the calibration interval
with <><>.
3. Confirm the setting with <ENTER>.
4. Quit the menu with <M>.
