Calibration, test, and diagnosing process loops. The PIECAL 532 is the best tool to do that!
Practical Instrument Electronics has introduced their PIE 532 loop calibrator. Offering all the functions of a loop calibrator, the 532 also delivers essential troubleshooting tools.
The 532 features the innovative Loop Diagnostic Mode, offered exclusively by PIE. The Loop Diagnostic Mode removes the need for a DMM by displaying the voltage, loop current, impedance, AC voltage and mode of operation simultaneously for the most in time efficiency. It’s capable of measuring ground fault error as a result of faulty wiring, flooded conduit and corrosion bridges. The unique diagnostic tool, available in every mode of operation, constantly updates parameters in real time and can even identify the most likely cause of loop failure.
With its Loop Diagnostic Mode, EZ-Dial knob for making adjustments, and the Dual Action EZ-Check switch for testing limits, the 532 from Practical Instrument Electronics is one of the leading Loop Calibrators available.
