UPS II Smart Loop Calibrator for Milliamps

UPS II Loop Calibrator

 

The UPS-II loop calibrator is an advanced handheld process calibrator tool. It 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.

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

4 to 20 mA linear 4, 8, 12, 16, 20 mA
0 to 20 mA linear 0, 5, 10, 15, 20 mA
4 to 20 mA sq.rt (flow) 4, 5, 8, 13, 20 mA
0 to 20 mA sq.rt (flow) 0, 1.25, 5, 11.25, 20 mA
4 to 20 mA 3.8, 4, 4.2, 12, 19, 20, 21 mA

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: 3.8, 4, 4.2 or 19, 20, 21 mA
Ramping The calibrator can source or simulate with high resolution a continuous up/down cycle between 4 and 20 mA or 0 and 20 mA. The travel time between limits is 60 seconds.
Reading in Percentage The calibrator can display readings in percentage of a 4 to 20 mA or 0 to 20 mA span and can also read or simulate dP-transmitters directly in percentage of flow.
