UM831011 can power (24VDC) and read 2-wire transmitters to perform field calibration. Output currents are adjustable with a 10 microamp resolution in both source and transmitter simulation mode.　

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

4-20mA lin 4 - 8 - 12 - 16 - 20mA 　　　

0-20mA lin 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 valve 3.8 - 4 - 4.2 - 12 - 19 - 20 - 21mA

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

In the valve series, auto-stepping will be

3.8 - 4 - 4.2 or 19 - 20 - 21mA

RAMPING The calibrator can source or simulate with high resolution a continuous up/down cycling between 4 and 20mA or 0 and 20mA.

The travel time between limits is 60 seconds.

READING IN PERCENT The calibrator can display readings in percent of a 4-20mA or 0-20mA span.

Unit also reads or simulates dP-transmitters directly in percent of flow.
