2.5 Function check
After unpacking, both components should be checked for any transport damage
and a short function check performed prior to installation.
For this purpose the sensor is connected to the display unit and the display unit
plugged into the mains. Shortly after the display unit is plugged in, the display is
activated and the instrument switches to the display of measurements. Here the
measured value taken in air is meaningless.
Note: It is only possible to check the operative zero point using very high
purity water!
If no messages appear in the lower part of the display, the function check is then
complete.
