This procedure can be used to adjust the humidity (RH) or temperature (T) measurement of the transmitter. If you want to adjust both RH and T (HMD62), repeat the procedure for each parameter.
Because stabilization of temperature and humidity takes time, you should expect the adjustment procedure to take at least 30 minutes for each adjustment point.
