This measurement is performed with 2 cables only,
sequentially as follows:
1. Integration of a “reference” period on one phase L1-L2 for
example
2. Integration of a “reference” period on one phase L1-L3
3. Calculation of the time delay between “reference” and
“measurement” periods enabling determination of the
phase order or phase rotation direction

Running of phase rotation direction detection sequence
Note 1:
In the following table, display of the symbol " " refers
systematically to the beginning of sequence
Note 2:
The sequence of the following table is described using:
- L1 on terminal “COM”
- L2 then L3 on terminal “+”
The same result is obtained if:
- L2 on terminal “COM” , L3 then L1 on terminal “+”
or:
- L3 on terminal “COM” , L1 then L2 on terminal “+”
