Thanks you again Sir. This information is AWESOME !!! Blessings Shalom.🇺🇸🤙🏽

Hello, bro can we do current AO trimming without removing the transmitter in service? Because there no option to remove the transmitter and isolation valves are not available. Tranmitters AO signal was drifted so i want to do D/A trimming. Is it possible?

[@InstrumentCalibration]

Hello Phill
Yes, you can perform AO trimming without removing transmitter. However, you need to make pressure to zero to set LRV, and you have to adjust pressure to exact same pressure as URV before performing span trim. If you don't do that URV will not be set.
Thanks for asking this question.
If you have any question, please feel free to ask.

@@InstrumentCalibration thanx bro

Please tell me what pressure sensor output is ma ?

[@ahmadraza-ch4oo]

Dear what mean by known pressure source, for 4ma o/p how much pressure should apply through known pressure source, can u guide

[@InstrumentCalibration]

Thanks for asking this question. Know Pressure source means Pressure calibrator. You can use any standard pressure calibrator. But make sure that your pressure calibrator gives accurate pressure. For 4 mA o/p pressure should depend your pressure transmitter range. If your PT range is 0 to 100 inches H2O then pressure should be 0 inches H2O for 4 mA Output.

Is pressure sensor output is ma?

[@jitubabusay2826]

Is pressure sensor s out put MA?

[@InstrumentCalibration]

Yes...It is mA Output
