Message: Not possible at this time...

[Anonymous user]

Hello...

I have Matrix UPS 3000 connected to spectrometer and computer.  The computer freeze up quite often for the last 2 weeks for which reason I am not sure.  Here is what I have done.

1) I did UPS TEST > Battery Cal TEST> DO and the message showed "Not possible at this time..."  what is that mean?  I couldn't find this error message in user's manual. 

2) I unplug the spectrometer from the wall and run on battery and it works fine, all the communication can run on UPS batteries.  I am not sure why the computer froze every 2-3 times a week.  Also, I don't know much about electronics so please explain in a layman's term.  Thank you for your help.

Hello,

I don't think it is likely the UPS is causing this problem with the computer.

A battery calibration only calibrates the reported runtime that the UPS has. Why it would not perform a calibration is outlined here ->  - Matrix UPS will not perform a runtime calibration | FAQs | Schneider Electric US Maybe you meant to run a self test or just battery test?

The isolation transformer in the Matrix would practically guarantees clean power to the attached devices. The only thing I am familiar with electronics having a problem or freezing is because of grounding issues which would have nothing to do with the UPS.

You may want to look specifically at the computer - is it older, is it something perhaps with the operating system on it rather than the power input, etc?
