B. BATTERY CHARGER
It is very important to use ONLY the approved charger supplied with
the Detecto-Pak 4 to recharge the battery pack. Substitute chargers may
damage the battery pack. After the charger has been plugged into the
Detecto-Pak 4 for 10 hours, the charger will automatically reduce itself
to the float mode. The float mode will maintain a charge in the battery as
long as it is connected to the charger. We recommend the Detecto-Pak
4 be connected to the charger whenever it is not it use. This will ensure
the battery is charged and the instrument is ready for use.
C. CHARGING PROCEDURE
WARNING
THE BATTERY MUST BE CHANGED OR CHARGED IN AN AREA
KNOWN TO BE NONFLAMMABLE TO REDUCE THE RISK OF
IGNITING A FLAMMABLE ATMOSPHERE.
The charging procedure is to set the Detecto-Pak 4 instrument Power
Switch to “Off.” Plug the battery charger into a 120 VAC receptacle,
then plug the battery charger output plug into the charger jack on the
Detecto-Pak 4. If connected in this correct sequence, the charger is on
and in the high charge mode.
Charging time is normally a 10 to 12 hour period if the instrument has
been operated for 8 to 10 hours. Although shorter charging times are not
recommended, if it becomes necessary use a 1.5 to 1 ratio to time in use.
Example: If you use the instrument for 4 hours, charge the battery for 6
plus hours to completely recharge it.
D. GENERAL INFORMATION - NICKEL METAL HYDRIDE
BATTERY
1. We recommend that a new replacement Nickel Metal Hydride battery
by cycled 2 times before regular use. First, fully charge the battery,
then discharge the battery by operating the instrument for 8 to 10
hours or preferably until it ceases functioning. Then fully recharge
for 10 plus hours. This is not necessary for new instruments shipped
from the factory and put into use within 2 weeks because the cycling
was accomplished in the factory.
