7. The transmitter is now in T calibration state. Analog output and optional display will still
follow the actual measured T value.
If you do not wish to perform the T adjustment at this time, press ADJ button
one more time. The red indicator LED is turned off and the transmitter
returns to normal mode. The calibration procedure is now finished.
8. Insert the probe into a known reference temperature (if Vaisala Humidity Calibrator
HMK15 is not used) and let the temperature reading stabilize.
Do not touch the adjustment buttons before the conditions have stabilized.
9. Using the - and + buttons, make the temperature offset adjustment by making sure the
U voltage is correct (you have to press either - or + at least once even if the value is
out
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. The red indicator LED is turned off and the
transmitter returns to normal mode. The calibration procedure is now
finished.
10. Insert the probe into another reference temperature.
Do not touch the adjustment buttons before the conditions have stabilized.
11. Using the - and + buttons, make the temperature gain adjustment by making sure the U
voltage is correct (you have to press either - or + at least once even if the value is correct).
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 blink alternately at a very fast rate (cycle
time 200ms) for a period of 2s after which the transmitter returns to normal
mode.
