Battery Features
Your instrument is powered by a rechargeable custom Lithium Ion
battery pack with a normal operating range of 6.5 - 8.4 V.
It is equipped with an internal backup energy source to protect your
data and settings in case the battery pack is momentarily removed from
the instrument. The backup remains charged by the battery pack,
provided the battery is functioning correctly. Your instrument includes a
number of features that help ensure the battery pack is always
sufficiently charged.
The table outlines the battery behavior in its different states.
Battery state Behavior
Below 7 Volts Instrument automatically switches off the back
light to prevent further power drainage. It
displays a flashing battery icon to indicate the
battery needs to be recharged.
At 6.5 Volts Instrument automatically powers down.
Charge of 25% or less Instrument enters Complete Powerdown mode
when powered off (rather than Sleep mode).
