Proceduces to Calibrate the UPS Smart RT 6000 VA

[Anonymous user]

Hi all,
I have to calibrate an UPS RT 6000VA on tomorrow mornig for my customer.
Because this UPS was replaced new battery modules, and when see the backup time on Power Chute via web browser is not correct.
Please do me a favor to let me know the steps to complete this job with this type of UPS.
Thank you so much.

To Ms. I Picked a Wanna,
Please help me as soon as posible when you see my question, if nobody help me.
I am Vietnamese, so our time is 10h16 pm now.

I get this job from my boss too late.

Hi,

Ensure that the batteries are at 100% charged, if it has an external battery pack attached make sure that those are charged as well. If you have a PowerChute Business Edition installed, you can use that to perform a software calibration. If you have a network management card installed on your UPS, you can use that as well.

If the software runtime calibration didn't work, you can follow the steps provided below for the manual runtime calibration:
1. Battery must be at 100% capacity when the Runtime Calibration is initiated/started.
2. The UPS must have at least a 30% load on it during the calibration.
3. The load cannot fluctuate more than +/- 5% during the calibration.
4. The battery must be discharged to at least 25% capacity (it is best to allow the UPS to shut off due to a discharged battery).

In addition to the above conditions, any UPS monitoring/shutdown software should be stopped from running in the background, and the serial cable should be detached from the UPS. This is necessary in order to prevent the software from shutting down the server/UPS due to an on-battery or low-battery condition.

Thank you so much Johnpro,
But the step 4 is quite confuse with step 1.
Can you explain more clearly?
Why must I do step 4 before I calibrate the UPS?
