That's a bit high, assuming all 3 meters are accurate. If it is too high, they can adjust or replace the transformer.

The given voltage is in Root Mean Square, or RMS which will be lower than the peak-to-peak. I have been curious about this for a while, bu; /html/shop-talk/2011-03/msg00147.html (8,741 bytes)

Places I've lived and worked in the last 30 years come in pretty close at 120V.

In other words, they display the peak voltage divided by 1.414 instead of true RMS. I've never seen a cheap meter that will display peak AC voltage directly. -- Randall ____________________; /html/shop-talk/2011-03/msg00160.html (7,946 bytes)
