8. The EVCC300 can perform testing with either 0° or 180°
earth leakage current. This means the current flowing
will either start at the positive direction zero cross over, or
negative direction zero cross over.
9. When the desired test has been selected press and hold the
TEST button
10. The test can take a while to perform. First the EVCC300 will put the charger into a charging mode and
measure the output voltage.
11. The EVCC300 will then perform a touch voltage test. This is to ensure that the charger earth or ground will
not raise in voltage to a hazardous level during the actual RCD / GFCI test. There are two test limits that can
be applied to the touch voltage test, 25 V and 50 V. These are set in the instruments settings screen.
12. Finally, if the touch voltage test has passed the EVCC300 will
perform the chosen earth leakage current test. The test result
is displayed in ms.
5.4.3 Interpreting test results
a.
Mains (line) voltage test
Should the charger fail to switch on the output voltage the test will stop
Check the charger connections and fuses
b.
Touch voltage test
Should the touch voltage test fail this will be because the charger either has no, or a poor, connection to the PE,
protective earth. Should this occur do not attempt to perform any more testing and consult a qualified electrician to
determine and rectify the fault.
