Battery Pack
Explorer uses a rechargeable nickel-metal hydride, rated for 300 charge/
discharge cycles, which is equivalent to a very heavy year of Explorer activity.
When the internal battery voltage is low, Explorer will display a low battery fault
and then after approximately 5 minutes, will shut itself off. This is a battery
protection measure, since deep discharging damages the battery. To resume
operation, connect
Explorer to an AC power supply using the AC adapter or
replace the battery pack with a fully charged one.
When the instrument is plugged into the AC adapter, the adapter will charge the
battery at a high rate. When the battery is fully charged the AC adapter will maintain
the full charge.
A fully charged standard battery pack will power Explorer for approximately 15
hours. This will depend on the oven temperature, whether or not the backlighting
is on or off and on the ambient conditions. An extended life battery pack will
provide approximately 6-8 hours of operation.
Before beginning operation of Explorer, the battery pack must be charged. You can
connect the battery charger to the battery pack while the battery pack is still
attached to
Explorer.
You can also remove the battery pack and replace it with a fully charged, spare
pack (
951-402-G1) and charge the battery pack independently of the instrument.
Removing and Replacing the Battery Pack
WARNING
Do not remove or recharge the battery pack in a hazardous location.
