Portable Loop Calibrator for mA and V



The GE Druck UPS-III Portable Loop Calibrator is a rugged and extremely compact loop calibrator. Measuring 3 x 5 in. (77 x 129 mm) and weighing just 9.7 oz (275 g), it fits comfortably in a shirt pocket. It is an essential tool for loop testing, instrument maintenance and valve set-up, with an easy-to-read display and simple-to-use time saving features. The UPS-III Loop Calibrator can supply power (source mode) and produce readings (measure mode) to perform field calibrations on 2-wire devices. The set-up menu enables the user to "source" or "measure" in either voltage or current and to perform continuity tests.

Graphic Display

The graphic display with menu-driven interface is easier to use than traditional knobs, switches, multi-function keys and dual key sequences.

Measure or Source 0 to 24 mA

An internal 24 V loop supply is available in both measure and source modes, essential during plant shutdowns.

Accuracy 0.01% of Reading

This includes 12 month stability and temperature effects. The UPS III can maintain a 4:1 calibration ratio with the latest instrumentation and is typically 20 to 80 times more accurate than a Digital Multi-Meter (DMM).

Simultaneous % Readout

Displays mA and the percentage value of 4 to 20 mA or 0 to 20 mA. The UPS III also converts mA readings to % flow. This is not possible with many loop calibrators.

Auto Step and Ramp

Outputs have adjustable rates (1 to 599 s) for single-handed loop testing, valve set-up and slew rate checks.

"Fast Set" Output

Allows values to be set to within 0.001 mA using the arrow keys. Holding a key quickly ramps the output to the next value. The system is ideal for alarm trip tests.

60 VDC Measurement

For loop diagnostics and maintenance of voltage output instruments.

Continuity and Switch Test Facility

This reduces DMM dependence when fault finding, checking loop integrity and testing switches.

HART Compatible

Internal 235 Ω loop resistor (menu selectable)

EMC compliance to EN 61326-1

Complies with heavy industry standard. Most loop calibrators are only suitable for light industrial use.
