Note :
The HI-3702 Clamp-
on Induced Current
Meter contains a
nickel-cadmium (NiCd)
battery, and uses
the Series H-491198-36
Battery Charger.
Before operating the
Series H-491198-36
Battery Charger, see
Safety Information on
page 6.
Never attempt to
recharge a non-
rechargeable battery.
APPENDIX A: SERIES H-491198-36 BATTERY
CHARGER
Introduction
The Series H-491198-36 Battery
Charger is a dual power source
battery charger. It charges 3.6
Volt 1400 mAH NiCd batteries and
is powered by 120-240 VAC line
power or 12.5 VDC. The H-491198-36
charger uses a -(dV)/(dT) negative
delta V technique to determine
when the battery is fully charged,
which is typically one hour. With
this technique, the charge state of
the battery has no effect other than
shortening the charge time.
Housed in a rugged enclosure, power enters the battery charger through a
power entry module, which contains the fuses, or an optional cigarette lighter
plug adapter. The front face of the battery charger displays LEDs that provide
the operating status. The battery charger connects to the device being charged
through a short cord terminated with a power jack.
An integrated circuit within the battery charger monitors the battery voltage and
controls the charging functions according to the charge state of the battery.
Charging the Battery
For the steps to charge a battery, see page 15.
Charging Indicators
The following LEDs are located on the front of the battery charger:
• POWER ON (green)—Indicates the battery charger is connected to the AC
power source.
• NO BATTERY (amber)—Indicates the battery charger does not detect
a battery.
• PENDING (amber)—Indicates the battery charger detects a battery.
Before fast charging can begin, the battery voltage must fall within
predetermined acceptable limits. A pulse-trickle charge is provided to bring
a depleted battery to a valid charge prior to fast charge.
• CHARGING (amber)—Indicates the voltage pre-qualification condition has
been met, and fast charge has started.
• COMPLETE (green)—Indicates a fast charging peak voltage is detected. The
Field Probe can remain connected to the battery charger indefinitely while
in this maintenance mode.
