PIE 334Plus Loop Calibrator

Overview

The 334Plus calibrates mA instruments at any access point in a loop. It sources and reads current, reads percentage of 4-20 mA span and measures DC voltage for power supply troubleshooting.

Its patented ground-leak detection powers a loop and displays both the total current and the uncontrolled leakage current, exposing faults caused by moisture, corrosion or broken insulation. Automatic stepping (2, 3 or 5 steps) and continuous ramping speed up calibration runs.

Features

  • Source and read 0.000 to 24.000 mA
  • Read loop current to 52.000 mA
  • Read -25.0 to 125.0% of 4-20 mA
  • Simulate a 2-wire transmitter with 2 to 100 V DC loop power
  • Power and measure 2-wire transmitters
  • Menu-selectable 250 Ω resistor for HART
  • Ground leak detection with automatic leakage indication
  • EZ-CHECK 3-output switch and 2-speed EZ-DIAL stepping and ramping
  • Backlit display
  • Includes rubber boot and test leads

Applications

  • 4-20 mA transmitter calibration
  • Loop wiring and receiver checks
  • Troubleshooting current leakage to ground

What's in the Box
