This test measures the leakage current in the protective earth conductor when the coffee
machine is switched on.
Test procedure
1. The coffee machine is assembled completely and has passed the insulation test.
2. Connect power plug of coffee machine to test equipment (A).
3. Switch on test equipment (B) and select earth leakage current test.
4. Then switch on coffee machine by turning the selector wheel (see detail).
5. Read off displayed leakage current.
6. If possible reverse power plug of coffee machine, connect it to test equipment
again and repeat measurement.
