Pressure compensation
GMT220 series transmitters have pressure compensation in the
software calculations. The factory set value for current pressure is
1013 hPa. For example in case of high altitude, the pressure value can
be changed by using the COM adapter (19040GM), a computer and a
suitable terminal software. The pressure is given in hPa.
