Description
The Druck UPS4E Handheld Electrical Loop Calibrator is a compact and rugged solution for process instrumentation maintenance, loop testing, and electrical calibration applications. Designed for convenient one-handed operation, the UPS4E can measure or source 0 to 24 mA and delivers an accuracy of 0.01% of reading + 1 count. Its dual mA and percentage display can be configured for linear or flow applications, while step, span check, valve check, and ramp functions simplify routine testing. The calibrator also provides 30 V DC measurement and continuity checking, 24 V DC loop power with mA measure or source mode, and a built-in 250 Ω resistor to support HART operation. With capacity for 100,000 datalog points and an automatic shutdown function for battery conservation, the UPS4E provides practical functionality for field service and instrument maintenance.
