During the test sequence:
The 1xI, 5xI and DC Ramp will trip the RCD.
Some EV charge points will auto-reset the supply voltage each time the RCD trips. In this case the MFT will
automatically proceed to the next test.
Older EV charge points do not always reset automatically.
In this case, the charge point will need to be reset manually.
To reset the charge point power the most convenient option is to use the Megger EV charge point adaptor (part
number 1012-732 (see “20. Accessories” on page 67).
Alternatively, remove the power from the charge point and re-connect.
The Megger MFT can be connected to the EV charge point adaptor using the optional Megger charge point adaptor,
part number 1012-732 (see “20. Accessories” on page 67.
Refer to the user guide for the adaptor for further details.

On conclusion of the test sequence, the test results can be reviewed by pressing the function key to cycle through
each result, or saved to memory and can be reviewed at a later date.
Always reset the RCD after testing, if it has not automatically reset.
