Medium Conductivity value Recommended rotary
switch position
Tap water 0.2 mS 3 kΩ
Saltwater (3.5 %) 35 mS 0.1 kΩ
Beer 1.4 mS 1 kΩ
Fruit juice 2 mS 0.3 kΩ
Milk, yogurt 3 mS 0.3 kΩ
Ketchup 15 mS 0.1 kΩ
In case of horizontally mounted instruments, the response
height is determined by the mounting height.
In case of vertically mounted instruments, the response height
is determined by the length of the probe rods.
The modification of the response height by turning the
conductivity value switch is not useful.
To adapt the response height, you can shorten the measuring
rods by sawing them off. Before shortening, unscrew the rods
out of the 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.
The max. rod (no. 2) defines the response height with single
point level switches or the upper switching level with two-point
control. It is the shortest rod.
The min. rod (no. 3) defines the lower switching level, it must
hence 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 - cnductivity setting (3) generally to switch position 3 kΩ.
Hence the instrument is already completely adjusted.
Take note of the instructions in chart "Examples of conductivity
values". The recommended settings take also influences such
as e.g. condensation or slight buildup into account.
