The Practical Instrument Electronics (PIE) Model 532 is the best tool for calibration, test, and diagnosing process loops. The Model 532 brings all the features you would expect from a loop calibrator and times new romanaving new ones. Make adjustments with the EZ-Dial™ knob or test limits with the Dual Action EZ-Check™ switch. Powerful ramping functions are only a button away on the Model 532. Save potentially hours of troubleshooting time on problem loops with the Model 532’s unique Loop Diagnostic Mode, only available at PIE! In Loop Diagnostic Mode, the loop current, voltage, impedance, AC voltage, and mode of operation are all displayed simultaneously eliminating the need of a DMM connection. Loop diagnostics is available in every mode of operation and truly is a diagnostic monitor, as parameters are continuously updated in real time. The smart diagnostic tool even indicates the most likely cause of loop failure! Loop Diagnostic features the ability to measure ground fault error caused by faulty wiring, flooded conduit and corrosion bridges.

Practical Instrument Electronics (PIE) Model 535 brings you the features of the original Model 532 for 10-50 milliamp process loops. On power up you can select 4-20 or 10–50 mA. The EZ-Dial™ knob and EZ-Check™ switch are all that's needed to make quick adjustments or set 0% or 100% of full scale. The EZ-Step™ button provides one-handed stepping. Automatic stepping and ramping modes allow hands-free testing and calibration of the process loop with HIGH accuracy and repeatability designed in collaboration with Nuclear plants. The model 535 offers the optional analog output of 10mV/mA proportional output for connection to chart recorders and data loggers. With the Model 535, calibration is easy as PIE.
