battery. If the rechargeable battery pack ever needs to be replaced, it can be
accessed by removing the screws from the bottom panel of the unit.

The 2-position switch located in the battery compartment must be set by the user
if the power supply method is changed. The up position is for the 9 volt battery.
The down position allows for either the AC adapter or the rechargeable
batteries. The AC adapter will trickle charge the rechargeable batteries if they
are in place or it will simply allow for line power operation of the unit.


WARNING: Replace batteries only in a non-hazardous environment.

The 9 volt battery should be replaced or the NiMH battery pack should be
recharged when the voltage drops below 6.4 volts. The battery voltage is
displayed when the instrument is turned on. While turned on, the battery
voltage can be displayed at any time by pressing the up or down arrow keys to
move through the display until the battery voltage screen appears. If, while
operating, the battery voltage drops below 6.4 volts, the display will
automatically switch to the display showing the battery voltage along with a
low battery message. After a low battery occurs, the unit will continue to
operate for approximately 8 hours. When the battery voltage falls to 6.2 volts
or below, the unit will automatically turn off.

Replace only with an approved 9 volt alkaline battery.

WARNING: Recharge batteries only in a non-hazardous environment.

The NiMH rechargeable battery pack is charged in the instrument using
Quest’s AC adapter #015-910. A discharged battery pack requires an
“overnight” charge of 16 hours. Leaving the AC adapter plugged in for
extended lengths of time or when operating the instrument will not harm the
rechargeable batteries.
