Good morning, I have an S series AI charm that was just installed to read analog from a table top scale. it is terminated on 2 and 4. when it is landed on the charm, the mA drop from 4.2 to 0. I can remove the device and simulate 4-20 with my fluke and it is fine. I can also install an interposing device like a digital scale, then output from the digital scale and it reads fine, diagnostics shows open loop with just the scale, but with the interposing device it is closed loop and reads correct? any assistance would be greatly appreciated.
