PIE 434 milliAmp Loop Diagnostic Calibrator

PIE 434 milliAmp Loop Diagnostic Calibrator

Product Description

Find Hidden Loop Problems with Ground Leak Detection
If you find a loop where the transmitter is calibrated correctly but all the readings elsewhere in the loop have a fixed offset this is due to a Zero Shift. This zero shift is typically caused by some current in the loop bypassing the transmitter. This might be caused by ground faults, moisture or corrosion.
Turn on Ground Leak Detection and use the PIE 434 to power up the loop. Any current that isn’t controlled by the transmitter or other current control element will be indicated as leakage on the calibrator’s display.
  • 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
  • Optional Accessories
    AC Adaptor 120 V (020-0101); 240 V (020-0100)
    NiMh Batteries & Charger 120 VAC/12V DC (020-0103)
    Magnetic hanging strap(020-0236)
