Battery Care
With average use, the nickel metal hydride batteries in the 4391A will power the
unit for 12 hours before needing recharged. The 4391A will maintain rated accuracy
until all the decimal points light, indicating that recharging is required. To recharge,
connect AC power to the unit. To fully charge the batteries requires approximately
16 hours. To prolong the life of the batteries, it is recommended that you
periodically allow the batteries to discharge until the decimal points light before
recharging. If the batteries lose the ability to hold a charge they should be replaced.
See
Chapter 5, Maintenance, page 16
for important precautions regarding static
electricity when opening the housing.
WARNING
Use only Nickel Metal Hydride (NiMH) batteries that have a
minimum capacity of 4500 milliampere hours (mAh). Do not
install batteries that are not Nickel Metal Hydride. Do not
install NiMH batteries that have less than 4500 mAh capacity.
Failure to comply may result in damage to the batteries,
damage to the instrument, and injury to personnel from
battery chemicals.
CAUTION
Long-term storage of this instrument can affect battery
performance and reduce battery life. Do not store the
instrument for long periods of time without recharging the
batteries (refer to page 17). Failure to comply may result in
reduced battery charge and shortened battery life.
