6.2.13 Restoring factory settings
!
Note!
• This function allows you to restore the factory settings. This is particularly useful if the device has
already been calibrated once and, for example, there is a fundamental change in the medium in
the tank.
• After restoring the factory settings, you must repeat the calibration.
To restore the factory settings, proceed as follows:
1. Turn the function switch to position 1.
2. Press the "+" and "–" keys simultaneously for approx. 20 seconds. During the time it takes to
restore the factory settings, the LEDs 1–5 light up consecutively.
3. The factory settings have been successfully restored if the green LED 1 and the yellow LED are
flashing.
You have now restored the factory settings and can continue with setting the measuring range and
the calibration.
