Hello,

I believe that I may have an issue with the unisab 2 board. At first I have suspected the slide position rotary transmitter to be at fault but after a number of setups and later, calibration of the transmitter. Along with putting in a new wire I accidently stumbled across a possible fault.
I kept getting a reading 0.027A between the signal and ground, this would not adjust on the Span switch. Whilst testing on the bench I got the same reading when the ground connection was detatched.
When I have the transmitter wired into the unisab I get the same reading.
Do you know if there is a ground connection anywhere on the unisab board suitable other than those on the same terminal block as the transmitter. I want to test the resistance between the terminal or connection pin 30 (transmitter ground connection)and another ground for the vdc supply. Unfortunately I cant find one and wondered if anyonecan shed any light
Any info would be very helpfull thank you.

Kind regards ,Allan
