PIE 535 Loop Calibrator

PIECAL 4-20 10-50 mA Loop Calibrator

4-20 10-50 mA Loop Calibrator (Includes Carrying Case, AC Adaptor & Wire Kit)

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.
