In Output Quality settings, only 3 types
of fixed voltage ranges can be chosen.
However, you can fine tune the MAX
O/P voltage in this function.
If the utility voltage is usually high, and
the connected equipment can work in
this condition, you can set the output
voltage range higher to reduce the UPS
from going to Battery Mode as often.
Low Transfer
Voltage
L.97V ~ L.103V

L.100V
In Output Quality settings, only 3
types of voltage ranges can be chosen.
However, you can fine tune the MIN O/P
voltage in this function.
If the utility voltage is usually low, and
the connected equipment can work in
this condition, you can set the output
voltage range lower to reduce the UPS
from going to AVR Mode or Battery
Mode as often.
Sensitivity

If the connected equipment can tolerate
more power events (Example: unstable
power often associated with stormy
weather), select Low Sensitivity. The
UPS will go to Battery Mode less often.
If the connected equipment is more
sensitive to power events, select High
Sensitivity. The UPS will go to Battery
Mode more often.

This function determines how the UPS
will switch to Battery Mode.
3 different output voltage ranges can
be chosen according to the quality of
the AC utility service in your location.
If your utility service is not stable, you
can select Poor (97V~144V). The UPS
will go to Battery Mode less often to
tolerate the utility power fluctuations.
If your utility service is stable, you can
select Good (103V~135V). The unit will
go to Battery Mode more often.
