PIE 535 Dual Range Calibrator
Specification
The Practical Instrument Electronics Model 535 Dual Range Loop Calibrator makes testing, troubleshooting, and calibrating your 4-20 and 10-50 milliamp process loops easy as pie. Change ranges in seconds - the Model 535 is two calibrators in one convenient package. Easily recall min/ max readings with the EZ-Check? feature. Powerful manual and automatic stepping and ramping features are found on the dual-action EZ-Step? Switch providing one-handed or hands-free operation. Independent step size, step time, and soak time parameters offer the most step and ramp flexibility of any calibrator in its class.
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.
