9-V Alkaline Battery Replacement
Power Options
There are 3 options for powering the QUESTemp 32: a 9-volt alkaline battery, a NiMH
(Nickel Metal Hydride) rechargeable 6-cell battery pack, and an AC adapter. A door on
the back of the unit allows the user access to the 9-volt battery. The rechargeable
battery pack is located inside of the unit. 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.
9-V Alkaline Battery Replacement
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.
