Hi Greg: From what I read in the documentation - a percision resistor is required to do this calibration on these cards. I asked multiple supply sources and no one could supply me with one about 6 months ago when I looked for them. The software will step you thru the calibration but the external resistor is required before you start. I will find the value and post here in the answers tomorrow. If you have a source I would like to get some for my stock! Thank you for asking.
Found this today in the Analog calibration manual: From reading thru the manual you need a mV voltage calibrator source. I don't currently have one and not sure of the prices, but suspect that $1000 or more is not out of line. Cut and paste from manual below. -------------------------- Calibrating the 1756-IT6I or 1756-IT6I2 This module only calibrates in millivolts. You can calibrate the module to either a -12…+30 mV range or -12…+78 mV range, depending upon your specific application.
Hi Bruce, thanks for sharing your knowledge. Great video
You are very welcome. As mentioned was one that I needed to do.
Thank you
For a zero reference you are expected to short the leads together to null out all that noise,
Hi OP - Never thought of that - will give it a try. Thanks
Do you have a procedure to calibrate a thermocouple card mv 1756 16 or 8 Channel
