UPS III IS
Druck Loop Calibrator
UPS III IS is a Druck product. Druck
has joined other GE high-technology
sensing businesses under a new
name_GE Industrial, Sensing.
Features
The UPS III IS is a rugged and extremely compact loop
calibrator. Measuring 3.5 in x 5.5 in x 1.7 in (90 mm x
140 mm x 42 mm) and weighing just 16.2 oz (460 g). 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
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 loop supply is available in both measure and
source modes, essential during plant shutdowns.
Simultaneous % Readout
Displays mA and the percentage value of 4 to 20 mA or
0 to 20 mA. The UPS III IS also converts mA readings to %
flow. This is not possible with many loop calibrators.
Step, Span Check and Value Check
Step quickly through linearity tests and zero/span
adjustments. In valve mode, seating can be checked and
the actuator set.

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.
50 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 220 S 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.
Accuracy 0.015% of Reading
This includes 12 month stability and temperature effects.
The UPS III IS can maintain a 4:1 calibration ratio with the
latest instrumentation and is typically 10 to 40 times more
accurate than a Digital Multi-Meter (DMM).
Other Features
• Adjustable display contrast
• Adjustable resolution
• Uses industry standard AA batteries
• Battery voltage and battery low indicator
• Information screen reports serial number, software
version and calibration date
• Primary reading in mA or %
• Auto power off (enable or disable)
• Pin protected closed case calibration
• Leather case with carry strap (Note: the UPS III IS must
be used in the case for harzardous area use)
