PIECAL Dual Range Calibrator

The PIECAL 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.
