PIE 434 Loop Calibrator / Read and source mA Signals / Troubleshoot Loop Problems with Patented Loop Diagnostic Technology
PIE Model 434
Calibrate milliamp (mA) loop functions
Source 0.00 to 24.00 mA (-25.0% to 125.0%)
Read 0.00 to 52.00 mA (-25% to 300.0%)
Simulate 2-Wire Transmitters 0.00 to 24.00 mA
Power and measure 2-Wire Transmitters 0.00 to 24.00 mA
Accuracy to 0.025% of span at 4.000 & 20.000
Within ± 0.005 mA from 4.00 and 20.00 mA EZ-Checks
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 appears as a Zero Shift and helps you
decide if the transmitter needs calibration or if there is some problem
in the loop wiring.
Easily adjust output by 0.01 mA (0.01%)
