Calibrate with Accuracy
Accurate to ±0.025% of Span at 4.00 & 20.00 EZ-CHECK outputs
Easy-to-Read Backlit Display
Locate Loop Current Leakages
Automatic indication of Loop Current and Leakage Current. Measure ground current leakage from faulty wiring, flooded conduit and corrosion bridges. Leakage typically appears as a Zero Shift and helps you decide if the transmitter needs calibration or if there is a problem in the loop wiring.
