I have a air flow transmitter that gives a 4 - 20mA output and I want to conect to a datalogger. Any suggestions on what type to purchase and how to configure it as all the ones I have seen on the site are voltage controlled. I spoke with tech support and they suggested using ADC-11 with a 120 ohm resistor which would convert 4 -20 mA into 0 - 2.5V. How do I configure the resistor.........feeling a bit thick at the moment
Anybody give me some advice?
