Fluke 726 Multifunction Precision Process Calibrator

We have been using model 725 and 726 Fluke Multifunction Calibrators for over 8 years now. This is a simple and user friendly instrument that I carry on my tool case on a daily basis. We recommend this product greatly, we have been working with Fluke products for over 25 Years.

I bought this calibrator 6 months ago. It is very convenient to make typical operations and more convenient than Fluke 725 calibrator. I don't need the user manual almost at all operations, I just do my work. But there are some questions to the Fluke 726 calibrator. 3- or 4-wire RTD measurement is not so easy because you have to connect "+mA" terminal (red) and "COM" terminal (black) to the low end and "-mA" terminal and "V" terminal to the high end of the resistor. It is annoying me. Typical 3-wire connections use two wires to the high end and one wire to the low end of the resistor. Fluke 726 connection with reverse wire order doesn't look trivial.

I replaced the battery and the numbers froze on the screen and then I try to turn it back on it wouldn't come on at all it wwas in my trunk I don't know why it wouldn't come on
