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.
Features
- Sources and reads milliamps
- Powers and reads 2-wire transmitters
- Reads and simulates DP transmitters in % of flow
- Auto-ramp cycling for endurance tests
- Auto-stepping for hands-free calibration
- Fixed calibration currents
- Fixed currents for valve stroking

| 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 Output currents can be changed manually or automatically. The time between steps is 10 seconds in the auto-stepping mode. |
| 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. |
