1.
After having made the low end adjustment, insert the probe into a
measurement hole of the NaCl (75 %RH) salt chamber in the
humidity calibrator. Please, note that the difference between the
two humidity references must be at least 30 %RH.
2.
The readings measured by the transmitter appear on the display, as
well as the text "Set Hi" on the lower left hand corner. If the
transmitter has no display, the LED indicator lights up.
