Discharge Pressure Transmitter

The pressure transmitter tester allows 1502 type pressure transmitters to be function tested very quickly to out those which have big offsets or are not responsive at all. Note the simple functions: Plug the pressure cable into the unit; plug the 24V adapter into the unit. Both displays will come on and should read near zero. Press the red button and 24VDC is applied to the pressure transmitter and with no pressure it should output 4 mA.  Press both the red and green buttons at the same time and the pressure transmitter output should switch to 20 mA. The current meter would then display the full scale reading (approximately 20 mA).
