Device error has been detected. Measurement
cycles are not being performed.

Updating

Software update is in progress.

Connecting

System state is being determined. This state is
shown after a software update has been
performed.

Uninstalling

DGA monitor is being uninstalled. Uninstallation
empties the DGA monitor of oil and prepares
the measurement system for transportation.

3.2 Starting Measurement

In normal operation DGA monitor repeats the measurement cycle continuously. You can only
start the measurement if DGA monitor is currently in standby.

1. Connect to the DGA monitor user interface and log in as an 

Admin

 user.

2. Start measurement from 

Control > Start Measuring

.

DGA monitor warms up during the first three measurement cycles. Measurements
made during the warm-up cycles are not guaranteed to be within the accuracy
specification.
