Testing Generator Using Measurement System
Enter the measurement system and select Preset Measurements.
Instruction on the proper hook-ups required are available through the HELP button, selecting Help using Preset Measurement.
The oscilloscope will display pre-configured for the testing.
Diagnostic information available through oscilloscope.
- Voltage Graph.
- Charging Current.
- Harmonic Content.
- Rotation Speed (Engine RPM).
Harmonic Content:
This is an expression of AC voltage contained in DC voltage.
The higher the percentage of harmonic content the larger the amount of residual AC voltage in the DC voltage.
High residual AC voltage is caused by weak or failing diodes in the generator. Generators which have harmonic content readings higher than specified (In TIS) should be replaced.
