How To Use a Process Meter - (5 Step Guide to Source / Simulate 4-20mA)

In this video I show you how to use a process meter to source or simulate 4- 20 mA using a fluke 789 process meter on Instrumentation loops.
I also talk about the different modes and how to determine the setup of aa current loop.
In this video, I’m going to show you an easy to follow 5 step guide to using a fluke 789 process meter - for sourcing or simulating 4-20mA loops, perfect for a whole host of instrumentation calibration and fault finding needs.
Quickly, before we move onto to the steps on how to use the fluke 789. we should discuss the difference between sourcing and simulate modes.
Transmitters and other sensors that give 4-20mA signals are connected to a plc or other input device that reads the current within the loop. These current loops are usually 24v DC powered.
These Instrumentation loops can be either have the 24Vs powered from the input card or the transmitter is externally powered and it provides the 24Vs for the loop power.
When using a process meter in place of transmitter to test a loop you will need to use it in a different mode depending on what is powering the loop.
If the transmitter was supplying the loop power, you’ll need to source the loop.
If the input card or isolator is powering the loop, you’ll need to simulate the loop.
Lets now lets look at the steps you’ll need to source or simulate, afterwards I’ll go through a few tips how to identify how a 4-20mA loop is setup so you will know what mode to use.
Remember electricity is dangerous, so only work on equipment you are competent to do so! And always check the voltages you are working with.

I just started an apprenticeship in which I thought I’d be doing nothing but electrical work but instrumentation is a huge huge part of what we do. I came from a commercial and residential background so this industrial stuff is so new to me. So much to learn about these instruments it seems

[@MarioPena-q6y]

Same! I come from industrial work I went from 5 year electrical apprentice to 1st year automation totally different language!

[@jonathancoker9916]

Same again lol. I went from an electrical job to an instrumentation job. I thought I would be doing some electrical still as an instrument tech but that was not true at all and I have to learn a lot about instrumentation lol. These videos help a lot!

Could you do a tutorial using a Hart 475 with a Fluke simulator and press pump to do loop tests/simulations and calibrations on Rosemount flow, pressure, level and temp?

Hi Bro, may I know what is the software you use to produce all this fantastic videos? Your videos are wonderful and full of values. Thanks.

[@InstrumentationControl]

Hi there. Thanks for your kind words. The software is called video scribe.

[@fltp1888]

@@InstrumentationControl It must be very time consuming and taxing to produce videos like this...tough job but you do an amazing task. Thanks a lot

Any videos for using a hart 475?

Can this meter source/simulate 0-10vdc control loop systems? Does it have a 250 or 500 ohm resistor in it? 250 0-5vdc or 500 0-10vdc?

[@InstrumentationControl]

Hi there, this meter will only source mA. Of course if you can use an external 250 / 500 ohm resistor with this meter for your voltage inputs.

[@BoandBeceadventures]

Thanks I’m trying to decide on a new meter. What’s the main differences between the 789 and 117 mentioned here please?

[@InstrumentationControl]

Hi James, The 789 will allow you to source and simulate 4-20mA current loops, if you work with industrial instrumentation then its the best version to go for. If you don't need that functionality then save yourself some money and go for the 117. If you do decide on either option please consider using my affiliate link in the description to amazon. It won't cost you anymore and helps my channel out :)

[@BoandBeceadventures]

@@InstrumentationControl I’ll gladly support you. However I think I need one somewhere in the middle. Can you recommend one that can simply read 4-20mA and do you have a video on how to do so?

[@InstrumentationControl]

​@@BoandBeceadventures It sounds like the Fluke 179 would be ideal for you James, it reads down to 0.01 mA on DC loops. Here's a link for you to use (my affiliate) amzn.to/3bYFfzF as for how to take a mA measurement if you look at my fluke 117 video there is a section for measuring mA, Its the same with the 179 only you have more resolution. The 117 only reads down to 0.001 Amps or 1 mA. No good for 4-20 loops. Hope this helps!

[@BoandBeceadventures]

@@InstrumentationControl thank you I will look first thing tomorrow morning and if I do purchase I will definitely use your link. Thank you again

[@BoandBeceadventures]

I've been a Industrial electrician for about 9 years but want to jump to being a instrument tech.. how can I start about that ?

[@carmemories4202]

Find a company looking to train a new instrumentation tech (hard) Or go to school (easy but expensive)

[@uzairasif2475]

Sir can we connect single 4-20 ma to 2 sources?(i mean from single 4-20ma can we run 2things?)

[@InstrumentationControl]

Hi there, Yes we can have multiple devices in a single 4-20mA loop. A common use case is a field transmitter with a local digital display within the loop that is displaying the 4-20 the transmitter is controlling as well being connected to the control system for remote indication.

[@ebbyt00]

thanks alot

[@InstrumentationControl]

No problem, hope it helped!

[@winstonli150]

I think you can Not assume the lead resistance is 0.1 ohm, if that is the case then you need another assumption to cover that

[@GorgeAndrade-jw6kl]

That transmitter is a Wireless WiHart device no 4-20mA source!

[@Àhmåd-RM-143]

💜💜

[@Trudeautthebestt]

BUT WHAT ABOUT THIS >>>...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.

[@Jay-fp8iy]

This is literally the opposite of what fluke instructions say to do?

[@anoopr-c6e]

kzbin.info/www/bejne/rnq2inavqrhqmqcsi=IdVe8MM1oC0yTUox

[@crmags]

This is NOT correct. Both Source and Simulate the dial remains on the Output mA setting, but the probes move between the 1st (from the left) and the 3rd. Loop power is used when you have a transmitter you want to verify is outputting the correct mA, but needs to be powered by the signal loop.
