(Pos. 10.1) - Automatic self-test [Self test]
This function interrupts the measuring process and performs a self-test for signal evaluation and coil control. To execute the function, press
the key . Confirm the question 'EXECUTE?' by pressing the key
being aborted. After completion, the result is displayed and normal operation resumes. This function is performed automatically on switching
on the device.
(Pos. 10.2) - Flow simulation [Simulation]
This function simulates a flow and can be used as a function test for connected devices. After activation, the flow rate can be simulated in
the main display ("S" visible in main display):
- Start: Press the key in the main display
- Adjusting: Enter a percentage value and press
- Finish: Press the key again to come back to adjusting display, to finish press
