OXITEST PLUS 7 OPERATING MANUAL
Newer
Oxitest Plus 7
units feature battery monitoring and protection circuitry. In the event the
Oxitest Plus 7
battery becomes deeply discharged, the protection circuit will disconnect the battery
internally when the battery voltage falls below a set threshold voltage. This typically occurs when a
unit with an older battery is left on the shelf for a prolonged period of time.
Notes:
!
If the battery is discharged to the point where the protection circuitry activates,
reconditioning of the battery may be indicated if an overnight charge does not restore the
battery to full capacity.
!
Once the protection circuitry has internally disconnected the battery,
Oxitest Plus 7
will
not power up by turning the finger probe. To reset the unit, the switch-mode AC adapter
must be plugged into the AC mains and connected to
Oxitest Plus 7
. This can be done
with the
Oxitest Plus 7
ON or OFF. Once reset,
Oxitest Plus 7
can be used with the AC
adapter, or without the AC adpater, once the battery has been fully charged.
!
When the protection circuitry disconnects the battery, all saved data and settings will be lost.
The
Oxitest Plus 7
battery can be removed for replacement or reconditioning through the battery
compartment access door on the underside of the unit.
Notes:
!
Once the battery has been physically disconnected from the unit,
Oxitest Plus 7
will not
power up by turning the finger probe. To reset the unit, the switch-mode AC adapter must
be plugged in to the AC mains and connected to
Oxitest Plus 7
. This can be done with the
Oxitest Plus 7
ON or OFF.
!
When the battery is physically disconnected from the unit, all saved data and settings will be
lost.
