When measuring in pressurized environments, the actual process pressure value must be given to HM70. The pressure can be given in the following
units:
- hPa: Absolute pressure given in the unit of hPa.
- barg: Gauge pressure given in the unit of bar. Indicates the pressure difference between normal atmospheric pressure and the actual process pressure.
- bara: Absolute process pressure given in the unit of bar.
- psia: Absolute pressure given in the unit of psi.
- Open the menu by pressing Open.
- Select Environment and press .
- Press Unit to change the pressure unit. Default unit is hPa.
- Press Set to set the ambient pressure value.
- Set the pressure value with the arrow buttons. Press +/- to change the sign of the pressure value. Press OK to save the value.
- To return to the basic display, press Exit.
