| Description | The positive values represent efficiency of the UPS in tenths of percent.
-1 If UPS supports this OID but the result is not available
-2 Load is too low to report efficiency
-3 Output off and efficiency is 0
-4 On battery, efficiency is not measured or calculated in this mode
-5 In Bypass, efficiency is not measured or calculated in this mode
-6 Battery charging, battery is charging and adversely affecting efficiency
-7 Poor AC input, the main input is outside the optimum efficiency range |
