6.4.6. Measurement procedure and results of "

" mode

1. Select

mode by means of the

key.

2. Connect the Black, Red and Green connectors of the split cables to the

corresponding input terminals of the instrument

Instrument connection for Phase Sequence Detection in a 400V three-phase system

3. Press the

START

key

to execute a test.



At the end of the test

the instrument emits a

double sound signal

indicating that the test
is

correctly

terminated

and

displays the values
alongside.
