UPS-III Druck Loop Calibrator
The UPS-III is a rugged and extremely compact loop calibrator. Measuring 77 mm x 129 mm (3 in. x 5 in.) and weighing just 275 g (9.7 oz), 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.

UPS-III Function introduction
Graphic Display：
The graphic display with menu-driven interface is easierto use than traditional knobs, switches, multi-functionkeys and dual key sequences.
Auto Step and Ramp：
Outputs have adjustable rates (1 to 599 s) for single handed loop testing, valve set-up and slew rate checks.
Measure or Source 0 to 24 mA：
An internal 24 V loop supply is available in both measureand source modes, essential during plant shutdowns.
“Fast Set” Output：
Allows valves to be set to within 0.001 mA using the arrow keys. Holding a key quickly ramps the output to the next valve. The system is ideal for alarm trip tests.
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).
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.
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.
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.
Complies with heavy industry standard. Most loop calibrators are only suitable for light industrial use.
Step, Span Check and Value Check：
Step quickly through linearity tests and zero/span adjustments. In valve mode, seating can be checked and the positioner set.
