Under what conditions does the alarm function of Phase reversal work?
I am verifying this after being asked by a customer why the alarm does not work even after matching the PM5330 settings and environment.
I set up "CBA" in the phase rotation of the basic setup.
The voltage was then applied in the order L1-L2-L3.
Initially, we expected the alarm to work in this state. However, the alarm was actually non-working. ・・(1)
Then, I changed the basic setup to "CBA" ⇒ "ABC" ⇒ "CBA" and the alarm worked.
After that, the alarm disappears when the PM5330 is turned on again.
(This means that we are back to (1).)
Therefore, I would like to know under what conditions phase reversal works.
