Have you measured the input voltage being fed to the UPS? Does the front panel indicate it is in boost or trim mode? Also, anytime you change the output voltage, it usually requires the UPS output to be turned off. Thus, any changes you make, I'd want to make sure they are accepted and actually apply. What was the output voltage set to prior to you changing it?

dear Angela,

yes we measure i/p:214VAC -o/p:246VAC in the same time.

thanks.
