Description
The Druck UPS4E-IS Handheld Electrical Loop Calibrator ATEX is an intrinsically safe electrical loop calibrator designed for process control loop testing, instrument maintenance, and mA device calibration. Its rugged and compact one-handed design provides measurement or sourcing from 0 to 24 mA with an accuracy of 0.01% of reading + 1 count. The calibrator features dual mA and percentage readout with linear or flow display options, along with step, span check, valve check, and ramp functions. It can measure up to 30V DC and perform continuity checks, while the built-in 250Ω resistor supports HART operation. The UPS4E-IS also provides 24V DC loop power with mA measurement or source mode and stores up to 100,000 data log points. Auto shutdown helps conserve battery life. The package includes a quick start and safety guide, alkaline batteries, test leads, USB cable, and calibration certificate.
