Charging The Battery; Saving Battery Life - Fluke 91 Series II User Manual

1 - 6

CHARGING THE BATTERY

TO AVOID ELECTRICAL SHOCK, USE ONLY A BATTERY
CHARGER THAT IS AUTHORIZED FOR USE WITH
SCOPEMETER TEST TOOL.
Use the following procedure to charge the battery pack and
power the instrument:
1. Connect the Power Adapter/Battery Charger to line
voltage.
2. Insert the Power Adapter/Battery Charger low voltage
plug into the Power Adapter connector of the
ScopeMeter test tool. The test tool can now be used
while the NiCad batteries charge slowly. If the test tool
is turned off, the batteries charge more quickly.
During operation, when the batteries are low, a blinking
battery symbol appears on the top right of the
display. When this occurs there is typically more than
30 minutes of operating time left.
WARNING
91/92/96/99/105
3. The Power Adapter/Battery Charger uses a trickle charge
for the batteries, so no damage can occur if you leave it
charging for long periods, e.g., through the weekend.
Typically a 21-hour recharge provides 5 hours (Fluke 91,
92, 96 and 99 : 4 hours) of use.

Saving Battery Life

When operated only on batteries, the test tool conserves
power by shutting itself down. If no new keys have been
pressed for 5 minutes or if the battery level is too low, the
test tool beeps and displays a message. This prompts you to
turn off the test tool or to continue. If no key is pressed
during the next 5 minutes, the test tool turns itself off
automatically.
When the is pressed ON, the last configuration prior to
the automatic shutdown will be restored.
Automatic power shutdown will not occur if Min Max is on
or if any key is pressed. Although recording will continue if
the batteries are low, memory retention is not jeopardized.
If the POWER ADAPTER is connected, there is no
automatic power shutdown.
