During routine OWS operation we observed a garbled display of 15 ppm monitor filled with random symbols.


What's wrong with it? Is such screen a sign of damage?

I have experience of dealing with this issue.

As per Maker's information: the cause of the garbled display is inductive loads, like motors and solenoids, connected to the external power supply line of the OWS/15 ppm.

To fix the screen, press the RESET key. This will not affect the measurement of oil concentration.
