Druck UPS4E Handheld Electrical Loop Calibrator

Key Features:

Measure or Source 0 to 24 mA: Capable of both sourcing and measuring current from 0-24 mA, making it highly versatile for loop testing and troubleshooting.

High Accuracy (0.01% of reading + 1 count): Delivers professional-grade precision for process calibration tasks.

Dual mA and % Readout (Linear or Flow): Simultaneously displays both the absolute current (mA) and its percentage of full scale—ideal for process control checks.

Built-in 24 V Loop Power Supply: Supplies loop power internally so you can test or source current without relying on external loop power.

Supports HART Communications (250 Ω Resistor Built-In): Ready for HART transmitter loops with the required 250 Ω resistor integrated.

Step, Span, Valve Check & Ramp Functions: Includes time-saving functions like step changes, ramp output, span checks, and valve setup – ready for field work in control systems.

30 V DC Measurement & Continuity Check: Enables diagnostics of 30 V loops and continuity testing for wiring and loop integrity.

Large Data Logging Capability (100,000+ data points): Captures large datasets for analysis, trending, and record-keeping of loop behaviour over time.

Portable & Rugged Design for Field Use: Compact design for one-handed operation, built for industrial environments, making it easy to carry and operate in the field.

Long Battery Life & Auto Power-Down: Powered by standard AA batteries with long operation time and automatic shutdown to preserve battery life.
