When the moisture detector (optional) is installed, an alarm is
activated if moisture is still present in the prepared sample
gas or a cable break is detected. It does not differentiate if the
alarm / cable break was triggered by moisture detector 1 or 2.
This information, however, appears in the display.
If the option "temperature signal" is built in, the unit has a
signal to indicate the actual cooler temperature. The option
"Moisture detector" includes the option "Temperature sig-
nal".
