9. Using the - and + buttons, make the temperature offset adjustment
by making sure the I
or + at least once even if the value is correct) and press the ADJ
button. The red indicator LED begins to blink faster (400ms cycle
time).
If you do not wish to perform the two-point T adjustment at this
time, press the ADJ button one more time to finish the calibration,
then skip the rest of the steps.
10. Insert the probe into another reference temperature.
Do not touch the adjustment buttons before the conditions have

12. Press the ADJ button one more time. The red indicator LED turns
off and the transmitter returns to normal mode. The calibration
procedure is now finished.
In case of calibration error both LEDs are blinked alternately at very
fast rate (cycle time 200ms) for a period of 2s after which the
transmitter returns to normal mode.
In case of using a HMT120 transmitter with display option, the
following texts are shown at the display during calibration:
"Probe cal: RH 1" corresponding the green LED blinking slowly
"Probe cal: RH 2" corresponding the green LED blinking fast
"Probe cal: T 1" corresponding the red LED blinking slowly
"Probe cal: T 2" corresponding the red LED blinking fast
"Probe cal: Error" corresponding both LEDs blinking alternately at
very fast rate
