This procedure is 1 of the alternative methods for completing the adjustment described in Calibrating and adjusting HMT310 series transmitters. The examples shown here are for RH calibration: the same steps apply to temperature calibrations when that parameter is selected instead of RH. |
Note that the difference between the 2 reference humidities must be at least 50 %RH. MI70 indicator is used now only as a terminal for visualizing and setting the transmitter's RH reading. |
