Druck UPS II-IS Intrinsically Safe Loop Calibrator

The Druck UPS II Loop Calibrator is an advanced hand held
process calibration tool. The UPS-II can power (24 VDC) and read
2-wire transmitters to perform field calibrations. Output currents are
adjustable to a resolution of 10 microamps in both source and transmitter
simulation modes.

FIXED STEPS
The calibrator can source or stimulate fixed calibration currents to
test or calibrate receivers and to stroke valves. Different current
levels are available from the menu.

4-20mA Linear	4 - 8 - 12 - 16 - 20mA
0-20mA Linear	0 - 5 - 10 - 15 - 20mA
4-20mA sq.rt (Flow)	4 - 5 - 8 - 13 - 20mA
0-20mA sq.rt (Flow)	0 - 1.25 - 5 - 11.25 - 20mA
4-20mA	3.8 - 4 - 4.2 - 12 - 19 - 20 - 21mA

Output currents can be changed manually or automatically. The time between
steps is 10 seconds in the auto-stepping mode. In the valve mode, auto-stepping
will be:

RAMPING
The calibrator can source or simulate with high resolution a continuous up/down
cycle between 4 and 20mA or 0 and 20mA. The travel time between limits is 60
seconds.

READING IN PERCENTAGE
The calibrator can display readings in percentage of a 4-20mA or 0-20mA span
and can also read or simulate dP-transmitters directly in percentage of flow.
