(11 %RH).
Make sure it sits tightly over the salt chamber.
8. Insert the DMT132 into the chamber. Do not remove the filter.
Make sure all unused holes are plugged and the transmitter is installed tightly on the
thread.
9. Give the RHCAL command.
The output from the command shows the currently measured RH value, and prompts
you to enter the value of the first reference (Ref1). This is the reference on the dry end,
which produces the offset correction for the measurement.
