Extending Battery Operation Time
Charging the batteries when they are not completely empty reduces the battery
operating time for the Fluke 43B. To keep the batteries in optimal condition,
observe the following guidelines:
• Operate the Fluke 43B on batteries until the
symbol appears at the top of
the screen. This indicates that the batteries are very low and that they need to
be recharged.
• To extend battery operation time, you can refresh the batteries.
During a battery refresh, the batteries will be discharged and charged
completely. A complete refresh cycle takes about 16 hours and should be
done about four times a year.
