very informative. dealt with a honeywell today that got stuck in analog and could not communicate with the honeywell communicator because of some alarm, my lead got me out this pickle by sourcing a lower temp than the alarm and trying to reconnect. i thought i had got it to crap the bed already lol
Great job on the video! I was impressed with how you explained the induced resistance from cabling when sourcing. I have a customer who requires annual calibrations and i just switched to a 724 from a decade. I found i was continusly off my 2-3*f when sourcing to transmitter from 724 when compared to decade. I WAS ADDING RESISTANCE THROUGH MY LEADS! The 724 should be accurate to 0.333*C for 385pt100. Thats .5degF. It was my leads adding resistance. Once i calulcated my resistance and compensated , my readings were back to normal. Thanks again for these videos! FYI dont invest in the TREX! super slow! I wish they didnt discontinue 475. Best comm on the market hands down imo.
thanks very much for your valuable video , but there is point not clear for me ; in video time 15:09 you use fluke to inject a 99.9 ohm to transmitter and the transmitter draw 4 ma and show a 0 c in HART communicator , but in the RTD Table the 100 ohm = 8 mA and its equivalent to 25% which i think equal to 30 c ? so kindly can you clarify this point . thank you
He doesn’t show an rtd table he shows a data card for a different transmitter notice the range on the sheet shows -10 to 40 degrees Celsius and on the transmitter he is working on is set to 0-100 degree Celsius so the mA output will be different. But the ohms to temperature is correct if you look at an rtd table for pt100
@@byronvanalstineif you watch the part I time stamped he was saying if you want a more accurate reading you could take away the exact resistance of the leads too. I was just wondering if you can zero the leads and the extra cable easily with the meter rather than measure it and deduct it manually
Thanks for your video!!! It's very useful! Go ahead don't stop making videos!
This was very insightful, i couldnt find this kind of content anywhere else. im intersted in this field and technology thank you mister !

thank you man for this video, you have easy way to explain for even a beginner
Thank you man...Your explanation is very clear and comprehensive
Fantastic video thank you It was very informative.
one of the best video calibration i see thank you very much
Thank you for sharing!, I'm looking forward for more upload videos like this. :)
Thanks for sharing. Loud and clear.
Excellent explain in sort video
Viel Erfolg
U r made my day
Very helpful video

Great!but can you do field calibration of temp.transmitter using beamex and hart comm?thanks.
I did use hart comm in the video. I don't have access to a beamex, but it's the same process as the hart
Sir.. Can u upload loop check of DI and DO loop
Very good
Where do you stack your leads for a 4 wire rtd?
👌🇰🇿
nice one
good job
Could you share step by step to reset hot back up for dual sensor function in TT by hart protocol Sir?
I thought you were calibrating it -10 to 40. Is that celcius?
Yes, Celsius
12:18
Is there any way to zero the leads on the meter itself?
As long as you are using 3 or 4 wire, it's doesn't matter as long a the resistance in the leads are equal.
