Relative Humidity Adjustment
Using Push-Buttons
A simple push-button adjustment is carried out by using two relative
humidity references: 11 % RH (LiCl) and 75 % RH (NaCl).
1. Carry out the chemical purge (if available).
LiCl reference
2. Press the ADJ button (see Figure 70 on page 138) on the
motherboard to open the adjustment mode. The indicator led starts
flashing.
3. Remove the filter from the probe and insert the probe into a
measurement hole of the 11 % RH (LiCl) in the humidity calibrator
HMK15. Use the adapter fitting for the probes of HMT334,
HMT335, HMT337 and HMT338.
4. Wait at least 30 minutes for the sensor to stabilize (the indicator led
is lit continuously). Adjustment cannot be done if the conditions
are not stabilized (indicator led is flashing).
5. When the indicator led is lit continuously, press the button LiCl~11%
to adjust the 11 % RH condition. After adjustment transmitter
returns to normal operation mode (indicator LED is unlit).
NaCl reference
6. When adjusting in the second reference 75 % RH, press the ADJ
button to open the adjustment mode. The indicator led starts
flashing.
7. Insert the probe into a measurement hole of the 75 % RH (NaCl)
reference chamber of the humidity calibrator HMK15. Use the
adapter fitting for the probes of HMT334, HMT335, HMT337 and
HMT338.
8. Wait at least 30 minutes for the sensor to stabilize (the indicator led
is lit continuously). Adjustment cannot be done if the conditions
are not stabilized (indicator led is flashing).
9. Press the button NaCl 75 % to adjust the 75 % RH condition. After
adjustment transmitter returns to normal operation mode (indicator
led is unlit).
