A level transmitter (0-100 in/h20 = 4-20mAdc) is bench cal'ed and installed on a liquid tank. Later, the transmitter is essentially re-ranged whereby 0-100 in/h20 is now equal to 20-4 mAdc output. Given the inversion, would you now also invert your calibration use of the zero and span...
Recently, I ran across an old removed "dumb" Rosemount DP xmitter (didn't get the model number) with only a zero and span adjustment on the outside of the xmitter housing. I was wondering if this type of old transmitter allowed the entire range to be shifted via the zero adjust? In other words...
