Did you run this test without AC input?
Also what happens when you cut off the AC mains without any load connected to it? Will the UPS continue to run or does it switch off as well?

Computer restarts as soon as power goes off, its not an ups . When i manually turn off the power to the UPS, it switches / relay works fine, but if actually if there is a power outage the relay does not...

Your question is slightly confusing. Do you mean that the computer is not powered by a UPS? If the computer is not connected to the UPS, then why have a UPS? If the computer is not connected to the UPS and restarts when you turn the UPS On, your circuit feeding the UPS is overloaded and the voltage dips. If the computer is connected to the UPS, and restarts when there is a power outage, the fault may lie in the reaction of the HP 800. This unit looks to be a line interactive unit and it is not a true on-line UPS. The line interactive and battery backup (no voltage regulation) units both should have a switch to battery power time of 4 msecs, or less. If this unit is faulty and the switchover time is longer, it will not continue to hold up the computer internal power supply. If you are trying to run a laser printer on the HP unit, it won't have enough output capacity.

I have a UPS 1000 VA with 12 V X 2 Battery, Problems: when we on ups input 200 V without load, it gives output 210 V. when load it gives 230 V on electricity. When Electricity cut off it gives 250 V. When...

arif qc, Are you using a DMM that is or will make "true RMS" measurements or is it an "average responding" type of voltmeter? Is this APC ups designed for 120 vac input/output or is this unit a 220 vac input/output type? Use only a "TRUE RMS" type DMM to make your measurements!!! I believe if you visit Tripp-Lite site, you will find a tutorial video clip of why you should use a true-rms meter to make measurements of output voltages. 12fixlouie

Compaq r3000 ups drops out while pluged in to a\c power

Did you ever get a resolution to this issue? I have the exact same problem. Someone advised that I should ensure that the Sleep mode is disabled through the config but that is already the case. Do you by any chance have the UPS in a non-air conditioned room where it might be getting too hot? Secondly, do you have both the battery leads connected to the battery pack or just one of the pairs is connected?
