Help with testing phase rotation

[sjm]

Hi guys looking for help with testing three phase for correct rotation.
I have a 2 probe voltage tester with left or right rotation indicator.
Probes are marked L1 and L2.
Would I be right in thinking that to test rotation I would need to test as follows.

Probe L1 to phase 1 probe L2 to phase 2.
Probe L1 to phase 2 probe L2 to phase 3.
Probe L1 to phase 3 probe L2 to phase 1.

Hope someone can help.

Thanks in advance.
Steve.

from my limited knowledge i would have thought you need a 3 lead tester! Are there no instructions available for the instrument?

If you know the make and model it would be easier going to the manufacturers site if you don't have instructions

Yes, that's it, just proving one phase is ahead of the other, this is from my Fluke T140 manual:

The rotary phase indication is always active.
The symbols R​

or  L are always displayed.
However, the rotary direction can only be determined
within a three-phase system. Here, the
instrument indicates the voltage between two
external conductors.
• Connect the instrument test probe with the
supposed phase L2 and the handle test
probe with the supposed phase L1.
• Touch Accessible electrode (11).
The voltage and the rotary field direction are
displayed.
signifies that the supposed phase L1 is
the actual phase L1 and the supposed
phase L2 is the actual phase L2
==> right rotary field
signifies that the supposed phase L1 is
the actual phase L2 and the supposed
phase L2 is the actual phase L1
==> left rotary field.
When re-testing with exchanged test probes​

the opposite symbol has to be illuminated
