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.

Loop Mismatch

Flashes “loop”

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.
