Issue:
My NMC show Runtime Calibration Refused due to UPS in invalid State when attempting to run a Calbration test on my SRTG UPS
Product Line:
Smart-UPS SRTG
Environment:
All models, All Serial Numbers
Cause:
The SRTG range of UPS do not have a runtime calibration test like the SRT range do, the NMC firmware is shared by the SRT and SRTG UPS which is why the option is showing.
A manual calibration test must be performed by removing AC power from the UPS and letting the battery power the UPS until it is discharged, and then AC power introduced again to charge the batteries.
