Incaseofhorizontallymountedinstruments,theresponseheightis
determined by the mounting height.
In case of vertically mounted instruments, the response height is
determined by the length of the probe rods.
Themodificationoftheresponseheightbyturningtheconductivity
value switch is not useful.
To adapt the response height, you can shorten the measuring rods
bysawingthemoff.Beforeshortening,unscrewtherodsoutofthe
plastic threaded part of the sensor to avoid damaging the probe.
The numbers of the rods are visible on the lower side of the thread.
The ground rod (no. 1) must have the same length or must even be
longer than the longest of the other rods.
Themax.rod(no.2)definestheresponseheightwithsinglepoint
level switches or the upper switching level with two-point control. It is
the shortest rod.
Themin.rod(no.3)definesthelowerswitchinglevel,itmusthence
be longer than the max. rod. It is not available with instruments for
single point level detection.
The electronics recognises if a min. rod is screwed in and changes
automatically from single to two-point control.
For products with a good conductivity (> 3 mS), set the rotary switch

condensation or slight buildup into account.
If there is danger of strong buildup or condensation, you can set the
instrument more insensitive by one rotary switch position.
The "Function chart" shows how to select the switching condition 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 cm
2. Switch on the power supply
3. Set the A/B switch to mode A
4. Set the rotary switch to position "TEST min."
5. Turn the rotary switch slowly clockwise until the red LED lights

The following settings apply to products with low conductivity
(< 3 mS)
