You can calibrate and adjust the transmitter with the adjustment buttons on the transmitter component board. The 2-point humidity adjustment is carried out by using two relative humidity references: for example saturated salt points 11 %RH (LiCl) and 75 %RH (NaCl). The difference between the two humidity reference points must be at least 30 %RH. The difference between the two temperature reference points must be at least 30 °C (86 °F).
|In push-button calibration, the transmitter outputs are by default relative humidity in the range 0 … 100 %RH in CH1 and temperature in the range −40 … +80 °C (−40 … +176 °F) in CH2 regardless what the actual transmitter settings are. Outputs mean in this case both the display and analog current outputs.|
