If there is danger of strong buildup or condensation, you canset the instrument more insensitive by one rotary switchposition.The "Function chart" shows how to select the switchingcondition of the output.The following settings apply to products with low conductivity(<3 mS)1 Fill the vessel until the shortest probe is covered approx.1 cm2 Switch on voltage supply3 Set the A/B switch to mode A4 Set the rotary switch to position "TEST min."5 Turn the rotary switch slowly clockwise until the red LEDlightsThe instrument is adapted to the medium, i.e. the relaydenergizes with max. level.The following settings apply to products with low conductivity(<3 mS)1 Empty the vessel until the min. measuring electrode is onlycovered approx. 1 cm2 Switch on voltage supply3 Set the A/B switch to mode B4 Set the rotary switch to position "TEST max."5 Turn the rotary switch slowly anticlockwise until the redLED lightsThe instrument is adapted to the medium, i.e. the relaydeenergized with min. level.The following settings apply to products with low conductivity(<3 mS)1 Fill the vessel until the shortest probe is covered approx.1 cm2 Switch on voltage supply3 Set the A/B switch to mode A4 Set the rotary switch to position "TEST min."5 Turn the rotary switch slowly clockwise until the red LEDlightsLevel detection for max. sig-nalLevel detection for min. signalPump control, A modeVEGAKON 66 - with relay output 17Set up32649-EN-070615
