Pressure transmitter COMPACT ECOnomic HYDROGEN-3

Zero point correction The zero point can be set easily with a magnet within ± 10% of the nominal range. To correct the zero point, hold a permanent magnet – a pin board magnet, for example – at the position marked on the pressure transmitter (i.e. the letter in a circle) for 1/2 to 2 1/2 minutes after the power has been switched on. To correct the zero point, atmospheric pressure has to be applied. Offsets for previously set values for initial and ultimate pressures will be corrected automatically by the device. A magnetic field applied outside of this time period has no effect on the setting....
