Hi! We don't have any videos on that, but it is possible to add multiple references on a calibration in CMX. For details, please have a chat with support via support portal at support.beamex.com/
Hi! For example the EURAMET Calibration Guide No. 18 says that (quote) "... the test is performed with at least one test load which should be selected in a reasonable relation to Max and resolution of the instrument... ". So there is no any strict rule. In some cases the weight is close to the max of the instrument, but it can be also on any important part of the range. Please read some more in the article here: blog.beamex.com/weighing-scale-calibration-how-to-calibrate-weighing-instruments For many other instrument types, the hysteresis is commonly tested in the middle of the range. Thanks,
Hi, thank you for a very informative video as always. I would just like to know if it is sufficient to calibrate the output of the transmitter only or must we do the calibration for the sensor and transmitter separately?
Hi! That is a very good question. Both methods are being used. So you can calibrate the sensor+transmitter combination, and if that is within accepted tolerance, then it is ok. If there is too big error, then you need to check if the error is from the transmitter or from the sensor. Please check e.g. this video for that kind of case with sensor+tranmitter: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-InRC9wa_BvU.html In some cases customer do also perform a "whole loop calibration", i.e. they put the sensor into a dry block and then record the final display in the control room. This way all components of the measurement loop gets checked at one calibration. Obviously, if there are too big errors, then each component in the loop needs to be checked. Hope this helps.

Hi! If you don't happen to have the MC5-IS manual, you can find it from our website, or pdf is here: www.beamex.com/app/uploads/2016/10/MC5-IS-User-Guide.pdf On the page 58, it is explained how to do the current "sink", i.e. to use external supply and have the calibrator controlling the current. If you need, please contact our support at support@beamex.com, or through the Support Portal: support.beamex.com/ and you will get help.
Hi. I have it sir, thx. Bui if I go to Current Sink, E: DC Current Source/Sink Generate it say that I need external V source. In the manual it is not shown how to connect this external V source that my MC5 need to generate this current. Please help@@BeamexCalibration
@@perica_jonev If you use the ET module, then the positive side of the external supply voltage is to be connected to the upper (positive) terminal in MC5-IS (the "arrow in" in the manual picture). And then the supply negative to the ET module's lower (negative) terminal. Similarly, you can also use the E module for this. Please note the related warning on page 59, starting as following: "Warnings! To avoid damages to MC5-IS' electronics, first select the correct Quantity and Function/Port. Then connect the circuit including the external supply to MC5-IS. Make sure that you don’t exceed the maximum current allowed by the instrument under test."
Hi Sir, can you please contact support at support@beamex.com, or submit a request in support portal at support.beamex.com/, and give a bit more detailed explanation on the issues, so they can solve the issue. Thank you.
Hi, the reference probe in this video is the Beamex RPRT (www.beamex.com/calibrators/temperature-sensors/) that is a high accuracy reference sensor with up to ±0.007°C stability, when used with the individual coefficients. That reference sensor has been calibrated in out ISO17025 accredited calibration laboratory. The sensor that is being calibrated is a regular lower accuracy industrial sensor. Hope this helps.

Hi, we like to follow the international definition of calibration which is "documented comparison against an accurate reference standard", and the adjustment/trimming is a separate process. In this video we did not adjust the sensor, and most often that is not even possible - instead you calculate the correction coefficients that can be used in the measuring device to correct errors. Thanks,

A dry block can be used to calibrate a temperature sensor. The selection to use internal or external reference sensor depends on the accuracy requirement of the sensor to be calibrated. If the Pt100 to be calibrated is very accurate, it is recommended to use a high accuracy external reference sensor.
You are just reading the indication of the two sensors with out a known standard sensor to compare to the unknown two sensors whom you are reading with your instrument. A calibration process is that you are comparing an unknown item with lower accuracy against a known item with higher accuracy. Raffy Garcia
HI, thanks for your comments. I agree with you. In this application the Pt100 sensors are calibrated comparing them against the calibrated internal reference sensor of the dry block. As mentioned in the video, you can also use an external reference sensor, which typically enables better accuracy (smaller uncertainty). The selection between internal or external reference depends on the uncertainty requirements of the sensor to be calibrated. Thanks!
