1. Different methods to measure analog output current of transmitter.
In First method, we need to connect multi meter in series with transmitter.
As you can see from the diagram, put multimeter in current measuring mode.
To put multi meter in current measuring mode, connect red probe to 400 mA port, and black probe to common port of multi meter.
After this, rotate the knob of multi meter in clockwise direction, and select ma function.
After this, press yellow button at once to select milli ampere dc function.
Analog current output can be measured in dc form. So, it is important to select milli ampere dc function.
Once you have put multi meter in current measuring mode, connect red probe to negative terminal of transmitter, and common probe to negative terminal of 24 volt dc power supply.
Now, multi meter in series with transmitter. So it will show 4 mA in normal condition.
And analog current value keep increasing, when measured value increases.
In second method, we need to connect multimeter probe to negative terminal and test terminal of transmitter.
As you can see from the diagram, this method is only applicable for transmitter, which has test port.
In order to measure output current, we need to connect red probe to negative terminal of transmitter, and common or black probe to test terminal.
After connecting probe to negative and test terminals, put the multi meter to current measuring mode.
And select mA dc function of multi meter. Once you select mA dc from multi meter, multi meter will show mA output of transmitter.

I've got a question for you, today I was testing a pressure transmitter which had been configured to be a flow meter. It was installed as a two-wire instrument. So when testing I powered the DP metre with 24 volts and I measured the milliamp outputs on the test points. At my LRV with a Beamex MC6 I measured a credible reading of around 4 mA, however, moving the test leads to a fluke 707, I had a current reading of around 1.7mA at LRV, can you think of an explanation for this??

Try DA trim

[@michaelcostello6991]

Does polarity of meter matter in series when measuring current.

[@InstrumentCalibration]

Yes...You must need to connect negative terminal of transmitter to 400 mA(red probe) terminal and common probe to negative terminal of power supply to measure mA value.
Please let me know if you need any further help.

Thank you for clarifying. What would happen if you got polarity wrong when measuring the current

Why do connect to negative terminal

How to generate 4 to 20 milliampere signal inorder to check our transmitter

You need 4 to 20 mA signal source to generate mA outout

Hello
I don't have it at present. But i will create one for you in future

How to check 4 to 20 mimli ampeare analog input in panels

[@InstrumentCalibration]

Hello Deepak
Thanks for your question. In order to check mA in panel, you need to connect DVM in series with negative cable. I hope you get your answer.

[@muse069]

@@InstrumentCalibration if connect DVM in positive terminal is possible or not?

[@itsmesheriff7315]

Why we check ma in series

[@InstrumentCalibration]

Thanks for asking this question. mA is analog current value, and it should always measure in series.
