We have have emerson and beamex harts on my work. After this video i think i have chose the one i will use.
Hi Caio, thanks for watching the video!
Emerson is a great communicator, but it is still "only" a communicator, so you will need additional calibrators and other tools to make calibration and trimming of a HART transmitter.
The MC6 has it all you need in one box.

Great Explanation . Can we do absolute pressure calibration as well with Beamex MC6 ?
Hi! Yes, you can do also absolute pressure calibration with Beamex MC6. To do that, you need to have the Barometric reference pressure module installed (or use an external one) and then all the other pressure modules can be used both gauge (positive and negative) and absolute. If your MC6 does not have a barometric module, that can be retrofitted. Or if you need it very seldom, you can also use an external barometric pressure module and plug it in when you need to calibrate absolute. I hope this helped, if questions, please feel free to contact us at any time.
Thanks, Heikki / Beamex
Excellent Video...Can you please explain as to why we do the Analog Calibration first and the sensor calibration thereafter....
Thanks!!
Hi Rajesh. As these trims are independent from each others, it does not matter in which order you trim them, as long as you make sure you trim them both. Thanks, Heikki / Beamex
How about putting out a service manual for the performance test for the MC6?
Hello and thanks for your comment! Indeed, there isn't such a manual available. With the performance test, if you mean to test that all functions and their accuracy, that could be done mostly be using the generation functions to generate a signal and the measurement function to measure that - that is one way to test the performance. But of course a real metrologically traceable calibration should be don eon regular intervals. Thanks, Beamex / Heikki
That's amazing! But how can you sure the pressure sensor of the calibrator is correct? Do you need to verify this calibrator periodically?
My unit is calibrated to FINAS accreditation and is certified every 12 months
nice
Thanks for your clarify.
So you used just upper sensor trim to modify the deviation that appear in test .
Therefore the lower sensor trim is not need because have good in test. So we should trim depending on document test !?
Hi, depending on the situation, both lower and upper trim may be needed. In this example case, the zero point was good, but the span had some error, therefore only upper trim was done.
If you also have some zero error, then lower trim is needed.
Thanks, Heikki / Beamex
Hi , what should I do with message that appear in mc6 at startup about overdue calibration .so can depend mc6 for transmitter calibration or should recalibrate mc6 and what should I do to do that .thanks
@@mohammedk1127 Hi, if that message appears in the startup, it means that the programmed calibration period has passed since the last calibration. By default, a new unit has a 1 year (365 days) calibration period. That is because MC6 has the 1-year uncertainty specified. It is naturally up to you how often you want to recalibrate the calibrator. You can go to the settings and change the calibration period if you don't want to calibrate it yet. Or if you have the MC6 recalibrated, you can set the new calibration date into the MC6. These are explained in the user manual. In case of any troubles, please contact our support at support@beamex.com. Thanks!
very well explained. How to calculate error: xxx(% of span(output)?
Hi, to calculate the error as % of output span, you need to calculate the error (in mA) of the output at a given point and then divide that with the output span (typically 20 - 4 = 16 mA), and then multiply with 100 to get a percentage value. For example, if you transmitter is giving out 16.1 mA when it should give 16.0 mA, then the span error is: (0.01 mA / 16 mA) x 100 = 0.0625 %. I hope this makes sense. Thanks, Heikki / Beamex
@@BeamexCalibration Hello Beamex Calibration. The results of % of span Calculated by your above method is not matching with your certificate in the video. For Example 15.8929 minus 16.000 = -0.1071 mA, the span error is: (-0.1071 mA/16 mA) x 100 = -0.669 % which is not matching with your -0.022 %. So, kindly request you to correct me if i am doing wrong or suggest me the formula. Thanks, Regards Prakhar Jain.
@@photoninstrumentationandse2773 Hi, that calculation from the output only is correct if the input is exactly at the nominal point. But in real life and as in the video, the input is not exactly on the nominal point, so you need to take that into account. So with the actual input pressure value, you need to calculate what the output should be for that input value, and then make the calculation between what it should be and what it is. Luckily the calibrator does it automatically no matter what the numbers are...
when you apply pressure ie 22.5 psi, why don't you accurately apply 22.5 psi? Instead you put 22.3 psi.
Does the mc6 do the job??
I'm using mc5
Thanks for the video
Yes. Otherwise you don’t need MC whatever, just Hart communicator will do.
Sir if range in minus ( -1 to 6 bar ) how apply pressure,and getting 4 ma
Hi, in that case the transmitter will give out 4 mA at the -1 bar point, and 20 mA at the 6 bar point. For the -1 bar point you will need some kind of a vacuum calibration pump. I practice, you don't always get down to -1 bar, depending on the current barometric pressure (on a rainy day, when barometric pressure is below 1 bar abs, it is not possible to go to -1 bar!). So in practice you would calibrate the low end in a vacuum point that you can achieve (e.g. -0.9 bar). Thanks, Heikki / Beamex
Is the pressure source connected to the transmitter as well as the calibrator or is it just connected to the transmitter?
Hi, the same pressure needs to be connected to the transmitter and also to the calibrator at the same time. The calibrator will be measuring the pressure accurately, so the transmitter can be checked/calibrated.
May I get this handbook in pdf, by download in Google or plz can u give me in comments,I can download
Hi Sir, This video is not available as pdf document, but we do have several eBooks and white papers available at:

Beamex mc6 calibrator does not support Yamatake Smart field communicator (SFC260). What to do for Yamatake SFC recognition.
Hi Sir, The SFC260 is a communicator and MC6 is also a communicator, so they are not planned to communicate with each others. Most likely the SFC support the Honeywell's proprietary DE protocol, that MC6 does not support. MC6 supports HART, FOUNDATION FIeldbus and Profibus protocols.
@@BeamexCalibration It can be adjusted with the Yamateke STG940 (STG-940 A1L 00000-R-C7E9) pressure transmitter SFN (SFC260). Bemaex MC5 or MC6 cannot recognize this Transmitter with HART/Fieldbus/ Profibus.
@@alacabuk Hi, maybe that transmitter is using the DE protocol, which is not supported by MC6.
But her only you can see the Transmitter Pressure on your Document device but not use a standard gauge for comparation
Dear Sir,
The Beamex MC6 is not only a documenting device, it is also a very accurate pressure reference (calibrator), so there is no need for a standard gauge. The MC6 includes very accurate internal pressure measurement modules that are far more accurate than typical standard gauge. So the MC6 both measures and documents the results.
Thanks,

Sir this video good, but my question is how u calibrated without 250 ohms resistance
Hi, the MC6 has a built-in 250 ohms resistor for HART compatibility.
Sir I want to know 250ohms resistance need or not during calibration of transmitter , using beamex MC6
Hi. The 24V internal loop supply in MC6 is provided with an internal HART compatible 250 ohms resistor. So if you use the internal loop supply from MC6, you don't need any external resistors with HART transmitters.
If you use some external loop supply (like a supply from DCS), then that external loop supply needs to have enough impedance to be HART compatible (if the external supply does not have enough impedance, then you need to add a resistor).
Hope this helps.
Thanks
Thanks sir, plz make video of bemex , clearly which which option have to go, for MA apply , and more videos
@@mohammadimtiyaz5824, I'm not really sure which kind of video you would like to see, but please check the Beamex UA-cam channel, there are a lot of videos on MC6 and how to make different connections. Thanks.
@@BeamexCalibration actually sir I worked in many plants as an instrument technician but never use beamex MC6, but last week I join power plant in Kuwait, here using beamex MC6,I am facing lot of problems, that's why I'm asking, I want which option I should go for ma apply, range , and how connection in CV and transmitter beamex MC6 and Hart together

Or you can contact the local Beamex personnel, you will find all contact information on our website at www.beamex.com/beamex-worldwide/ .
The MC6 manual has pretty good explanations of the connections, if you don't have a manual you can download one from the website at www.beamex.com/manuals-brochures/
So, my question is why do you not have a certified test pressure gauge on your pump to know exactly what pressure you are inputting instead of relying on the transmitter which could be off. I work in the oil and gas custody transfer area and this would not pass as a good test because their is not a certified reference gauge that your verifing and then calibrating the instrument.
Bro, one pressure tapping from pump also goes to the mc6, which knows it’s job
Why did you plugged the low pressure port? Really good calibration device btw !
The low pressure port is not plugged. I can see it may seem like that in the video, but there are two high pressure ports in parallel, so the other one is plugged not to leak. The transmitter's low pressure port is open to atmospheric, like is the low (reference) connection of the pressure module in calibrator also. So they both refer to current atmospheric pressure.
If you calibrate a very low pressure transmitter, then it is best to connect the low side of the transmitter and the low side of the calibrator together with a pressure hose, to make sure they have the same pressure in their low ports. Also, in case of a very low pressure calibration, any winds, draft, air conditioning, etc. can have effect to the result if the low sides are left open to atmospheric and not connected together.
I hope this answers.
Heikki Laurila Crystal clear! My bad not to recognize the two quick vents on the other side of the sensor adaptor. I started 15 years ago as an instrumentation field technician during construction, pre commission and later maintenance on the biggest natural gas plant here in Argentina... MEGA Loma La Lata. I went thru all that you have described, specially the windy part....hahahaa...! Really good to hear that complete and accurate explanation from you... Thank you !

Hi Henry. Thanks for your comments, it is nice to hear that from a long-time calibration professional like yourself. Sounds that you have a pretty big site over there...
Happy Calibration!
@@HeiJuLau oo
can HART be calibrated by Computer? (HART modem)
If we talk about metrological traceable calibration, it is NOT possible to do that only with a Computer (with HART modem) only. Also, it is not possible to do that with a HART communicator only.
In order to make a proper metrological calibration, you always need an accurate traceable reference standard telling you what is the true value. You can then compared your HART transmitter against that true value. So in addition to your computer, you will also need a calibrator.
As there are terminology differences, it is good to mention that sometimes people talk about “calibration”, when they actually mean changing some parameters/settings in the transmitter. This is possible to do with just a computer and HART modem.
For more information, please take a look at the article in Beamex blog:
