6.5.2 Testing The VCC3 Inverter (With Diagnostic Function)
With the aid of a multi-meter, a number of points can be tested on the inverter while it is in a running state.
To carry out these tests the probes on the meter need to be sharp and have fine points. The inputs to the
inverter and the output can be checked.
