The Practical Instrument Electronics (PIE) 532 loop calibrator is the best tool for calibration, test, and diagnosing process loops. The PIE 532 loop calibrator brings all the features you would expect from a loop calibrator and time saving new ones. You can easily make adjustments with the PIE 532 loop calibrator's EZ-Dial Knob or test limits with the dual action EZ-Check Switch. Powerful ramping functions are only a button away with the PIE 532 loop calibrator.

Save potentially hours of troubleshooting time on problem loops with the PIE 532 loop calibrator's unique Loop Diagnostic Mode. In Loop Diagnostic Mode, the loop current, voltage, resistances, AC voltage, and mode of operation are all displayed simultaneously, without the need of multiple DMM connections. Loop diagnostic is available in every mode of operation and truly is a diagnostic monitor, as parameters are continuously updated in real time. The PIE 532 loop calibrator is a smart diagnostic tool that even indicates the most likely cause of loop failure!
