3.4.4 Setting table VARiON K (potassium sensor)
The basic settings are taken over from the VARiON A sensor but can
be adjusted separately afterwards.
These sensor settings are only available if in the sensor
settings for the
VARiON A the setting VARiON K was set to
Active (see section
3.4.2
).

Fixed range
Temperature mode
(only with Measuring
mode : K (mg/l) )

°C

°F
Unit of the measured temperature value
(Celsius, Fahrenheit).
Temp. adjustment
(only with Measuring
mode : K (mg/l) )
-1.5 °C ... +1.5 °C The temperature compensation function
enables the temperature sensor to be
balanced against a reference temperature
measurement (displacement of the zero
point by ±1.5 °C).
Notes:

Due to the thermal capacity of the sen-
sor, it is necessary to place it in a con-
tainer with at least 2 liters of water.

Leave the sensor in this container for at
least 15 minutes while stirring occa-
sionally, then carry out the adjustment.
If the temperature difference of the
water and sensor is > 10°C, leave the
sensor in the container for at least one
hour while stirring occasionally.
Conc. offset
-10.0 mg/l ... +10. mg/l Constant value that is added to the mea-
sured value.
Save and quit
The system confirms the saving of the set-
tings and the display switches to the next
higher level.
