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 ts
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.

Graphic Display
Auto Step and Ramp
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
eects. 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 %
ow. This is not possible with many loop calibrators.
Outputs have adjustable rates (1 to 599 s) for singlehanded loop testing, valve set-up and slew rate checks.
“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.
60 VDC Measurement
For loop diagnostics and maintenance of voltage output
instruments
Continuity and Switch Test Facility
This reduces DMM dependence when fault nding,
checking loop integrity and testing switches.
HART Compatible
Internal 235 Ω loop resistor (menu selectable)
EMC Compliance to EN 61326-1
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.
