•	Calibrate with Lab Accuracy Accurate to ±(0.01% of Reading + 0.002 mA) PIECAL 434 is *more accurate than similar calibrators* - within ±0.004 mA at 20 mA output!
•	Easty-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.
