Frequently asked questions
Can I measure a 4-20 mA loop without disconnecting wires?
Yes. The clamp measures the loop current without breaking the loop, so the wiring does not need to be cut.
Can it drive the 4-20 mA output for remote testing?
The listing says it can change the 4-20 mA output automatically for remote testing. Check the manual for the exact procedure before connecting it to a live control loop.
