  • High Accuracy Milliamp Loop Diagnostic Calibrator PIECAL 434 High Accuracy Milliamp Loop Diagnostic Calibrator PIECAL 434

PIE 434 Automated Diagnostic 4-20 mA Calibrator

Quick Overview

The Practical Instrument Electronics (PIE) 434 automated diagnostic 4-20 mA calibrator allows you to check, calibrate and measure all of your current signal instruments in a 4-20 mA DC loop. It can be used at any access point in your loop. You can calibrate recorders, digital indicators, stroke valves or any instruments that get their input from a 4-20 mA loop. Quickly diagnose ground fault and current leakage with the PIE 434 automated diagnostic 4-20 mA calibrator's loop diagnostic technology. PIE 434 calibrators also feature automatic output stepping and ramping. Press and hold the dial to automatically step from 4-20 in two, three or five steps or choose a continuous ramp.

Features
  • 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 -99.99 to 99.99 V
    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)
    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.
  • Faster Calibrations
    Three output EZ-CHECK switch
    2 speed EZ-DIAL
    Stepping & Ramping
  • Includes Rubber Boot & Test Leads
  • Optional Accessories
    AC Adaptor 120 V (020-0101); 240 V (020-0100)
    NiMh Batteries & Charger 120 VAC/12V DC (020-0103)
Advantages of the PIECAL 434 over the Altek 434
  • Larger Display withBacklight
    Easy viewing in dark locations
  • Easy selection of 250 Ω Hart Compatible Resistor
    No disassembly to move internal jumper
  • Detects Loop Current Leakages
    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.
  • More Resistant to Accidental Damage
    Rubber Boot and Stronger Switches
  • Less Expensive Battery Changes
    Four versus six "AA" batteries
Ground Leak Detection

Have you ever replace 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 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 PIECAL 434 display.

The PIECAL 434 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.

    For the size it is a mighty piece of equipment. Paid for itself many times over. Only issue is that the press on the leads are a little stiff. Other than that it is great instrument.
