CHE: The UPS will automatically detect the neutral loss. If neutral
loss is detected, an alarm will be generated, if the UPS is turned
on, it will transfer to battery mode. When neutral is restored, the
alarm will NOT be muted automatically, and the UPS will NOT go
back to normal mode automatically.
Here, you must mute the alarm and make the UPS go back to
normal mode manually. The operation is: Firstly, enter this menu
and press the "Enter" key to make the "CHE" flash; Secondly,
press the "Enter" key again to activate the neutral detection
(check). If neutral is detected, the alarm will be muted, and the
UPS will go back to normal mode; if not detected, the UPS will
continue alarming and stay on the latest status until the neutral is
detected well at next manual checking operation.
CHE is default setting.
Setting
Parameter 2: Select "Add" or "Sub" function to adjust battery
voltage to real figure.
Parameter 3: the voltage range is from 0V to 9.9V, the default
value is 0V.
Setting
Parameter 2: you may choose Add or Sub to adjust charger
voltage
Parameter 3: the voltage range is from 0V to 7.0V, the default
value is 0V.
NOTE:
*Before making voltage adjustment, be sure to disconnect all
batteries first to get the accurate charger voltage.
* Any modification should be suitable to battery specifications.

Parameter 2: you may choose Add or Sub to adjust inverter
voltage
Parameter 3: the voltage range is from 0V to 9.9V, the default
value is 0V.
Setting
Parameter 2: it always shows OP.V as output voltage.
Parameter 3: it shows the internal measurement value of the
output voltage, and you can calibrate it by pressing Up or Down
according to the measurement from an external voltage meter.
The calibration result will be effective by pressing Enter. The
calibration range is limited within +/-9V. This function is normally
used for parallel operation.
