Hello CSI,
I have a pH analyzer controller that sends out a 4-20 mA signal. Is the CU100 able to compensate for various voltages in the output current signal?
Setup:
pH analyzer: Yokogawa EXAxt 450
pH output signal @ pH 6.93: 11.92 mA (measures 15.96 V on the analyzer)
reading on CR1000 datalogger with 100 ohm resistor 11.96 V = "NAN" reading
Thanks,
Jon
Corrected the problem. The resistor I had was 1000 ohm instead of 100 ohm. Once I switched to a 100 ohm resistor, the readings were correct.
