[QUOTE="Papermaker85, post: 5976288, member: 572595"] call me a retard, better beable to prove it.. BTW the answer to the question is... swich the leads to the correct placemant to measure mv then switch the DMM to millivolt DC check the spec sheet(coes with the transmitter) for current flow when NC/NO (most times .04ma..) if its not you have to calabriate it to spec.. secondly when flow/temp/pressure increses you gong to get more current flow, to check this you simply SERIES the meter(since is Direct Current or DC) with your common by determinating it from the PLC/panel/device and taking the + DMM lead to the common(coming off the drvice AKA transmitter) and the NEG meter led to the terminal/test on the device/panel/plc... as pressure increases you current should increase.. when it reaches the programed parameters to activate the shut down you should beable to see the same ma DC on hte meter AND manually in PSI/temp VIA gauge etc... so in short you simply test the DC amperage in series between the device and PLC/Jbox to calabriate/test it..
