Note: - If no supply voltage is shown, check the status of the
electrical supply to the EV charging point and ensure the
RCD is switched on.
Note: - If N< >L is displayed, the live and neutral are reversed.
For MFT1800 series, the test should proceed as normal.
For MFT1700 series, the test will be aborted.

charge point.
6. Press the TEST button on the MFT. The test sequence
will run as in Table 1 shown above.
7. On completion of the test, the display will show "End" in
small letters
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, Type
1012-732.
Alternatively, remove the power from the charge point and
■
re-connect.
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.
Refer to storage and recall of test results in the main user
manual.
