PIE 434 milliAmp Loop Diagnostic Calibrator

PIECAL 434 you can check, calibrate and measure all your current signal instruments in a 4 to 20 milliamp DC loop.



  • Calibrate Milliamp Instruments
    Source 0.000 to 24.000 mA & -25.00 to 125.00% of 4-20 mA
    Read 0.000 to 24.000 mA & -25.00 to 125.00% of 4-20 mA
    Read -60.00 to +60.00 VDC
    Simulate 2-Wire Transmitter, Power & Read Transmitters
    Menu Selectable 250 Ohm resistor for HART compatibility
  • Calibrate with Lab Accuracy
    Accurate to ±(0.01% of Reading + 0.002 mA)
    PIE 434 is more accurate than similar calibrators – within ±0.004 mA at 20 mA output!
  • 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.
  • Faster Calibrations
    Three output EZ-CHECK switch
    2 speed EZ-DIAL
    Stepping & Ramping
  • Includes Rubber Boot, Deluxe Hands Free Carrying Case & Test Leads
