The Druck UPS-II Loop Calibrator is an advanced handheld process calibrator 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 UPS II loop 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.

Output currents can be changed manually or automatically using the UPS-II loop calibrator. The time between steps is 10 seconds in the auto-stepping mode. In the valve mode, auto-stepping will be 3.8 - 4 – 4.2 or 19 - 20 - 21mA.
Ramping
The UPS-II loop 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.
