2 Turn potentiometer (B) to complete left position
3 Turn potentiometer (B) slowly clockwise until the relay output
switches and the yellow control lamp changes condition
4 Turn the potentiometer approximately 15° in the same direction
5 If the relay output does not change, you have to switch to the next
range (10 kΩ).
If the relay output has switched, empty the vessel until the electrode is
uncovered.
The relay output must now switch again.
Adjustment in liquids with resistance range up to 10 kΩ
