  • PIECAL 334Plus with Leakage PIECAL 334Plus with Leakage

PIE 334+ Milliamp Loop Diagnostic Calibrator

Quick Overview

Have you ever replaced a "faulty" transmitter only to find the problem was somewhere else in the loop? And did you end up throwing the transmitter away after you fixed the other problem "just in case" the transmitter was faulty?



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 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.



If you have some loops that are erratic after it rains, there may be moisture present in a junction box where insulation has broken down. Turn on Ground Leak Detection and use the PIECAL 334Plus 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 PIECAL 334Plus display.



The PIECAL 334Plus powers up the 2-Wire transmitter or loop and indicates the total current and the uncontrolled current. This provides information useful in troubleshooting loop errors.

  • Calibrate with Accuracy
    Accurate to ±(0.02% of Reading + 0.002 mA)
  • 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.

    We originally ordered the PIE 541 and were very impressed with it. We ordered the 334+ a couple of month afterwards and just as pleased.
