7.9.6 Service D/A monitor

The service D/A monitor gives you the option of outputting internal measurement and intermediate parameters from COMPAX in the form of analogue voltage in the range of ± 10V via X11 (X17 with COMPAX 1000SL) and visualizing these by means of an oscilloscope. This provides you with a capable aid for making the unit functions clear and qualifiable, especially during the start-up.

This function (which is available in all units) provides you with two analogue output channels with a resolution of 8 bit and these are updated every 100 µs.
