Hello, this is the apcupsd Cable Test program.
This part of apctest is for testing Smart UPSes.
Please select the function you want to perform.

1) Query the UPS for all known values
2) Perform a Battery Runtime Calibration
3) Abort Battery Calibration
4) Monitor Battery Calibration progress
5) Program EEPROM
6) Enter TTY mode communicating with UPS

First ensure that we have a good link and
that the UPS is functionning normally.

Checking estimated runtime ...
Current runtime is 30 minutes
Checking for battery level ...
Battery level is 100.0 -- OK

The battery calibration should automatically end
when the battery level drops below about 25, depending
on your UPS.

I can also optionally monitor the progress
and stop the calibration if it goes below 10. However,
in the case of a new battery this may prematurely end the
calibration loosing the effect.

Do you want me to stop the calibration
if the battery level goes too low? (y/n): y
