PIE 334PLUS Datasheet (PDF)

 

Calibrate milliamp instruments and find hidden loop problems.

  • Calibrate Milliamp Instruments
    Source 0.00 to 24.00 mA & -25.0 to 125.0% of 4-20 mA
    Read 0.00 to 52.00 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 Accuracy
    Accurate to ±0.025% of Span at 4.00 & 20.00 EZ-CHECK outputs

 

  • 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.

    Stepping & Ramping

 

  • Includes Rubber Boot, Test Leads & Deluxe Hands Free Carrying Case (020-0211)

 

  • 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)

 

Find hidden loop problems – Ground Leak Detected with Loop Diagnostics

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 PIE 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 PIE 334Plus display.

The PIE 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.

Typical Error Conditions

334PLUS
The PIE 334Plus is supplying the loop voltage. A calibrated transmitter is limiting the loop current to 12.00mA. An additional 0.51 mA is not controlled by the transmitter and is leaking somewhere in the loop. Click on the link below to see a video demonstration of Loop Diagnostics in action.
334PLUS
The PIE 334Plus is supplying the loop voltage. There is a control loop error. This may be a transmitter (set for upscale burnout) with a bad or missing sensor, or a short in the loop
