Power Down Mode
The instrument utilizes two power down modes to conserve battery life during nonuse times. The
power down mode is preset in the Configuration Mode.
Standby Mode - The instrument is ready to measure, however the display is not on. A button
press, measurement, power connection (if not connected), or USB connection will wake up the
instrument. Standby mode does not occur when the AC adapter is attached to the instrument.
Off Mode - The power button must be pressed and held for three seconds to wake up the
instrument before a measurement can be taken. Plugging in the AC adapter will also wake up the
instrument from power off mode. Off mode does not occur when the AC adapter is attached to the
instrument.
About the Battery Pack
General
The battery packs for your new instrument come in a low to medium charge state and should be
charged before use (up to 4 hours for full charge).
A charged battery pack may eventually lose partial charge if not used for an extended amount of
time. You should charge the battery from time to time and store in a cool environment when not
in use to maintain battery performance.
The battery pack can be charged in the instrument (see Connecting the AC Adapter) or by use of
the charging station. The charging station is useful for charging up to two battery packs.
Lifespan Expectations
Lithium-ion batteries typically decay to 80% capacity after 400 charge cycles (see chart below). A
charge cycle can be defined as several partial charges equaling 100%. Partial charge and
discharge cycles will help maintain the life of the battery. It is best to avoid full discharge and
charge cycles. After roughly 400 charge cycles are reached, the amount of measurements you
can expect to achieve from one full charge is reduced. At this point, you may wish to replace the
battery pack.
Disposal
Dispose of the battery pack in a designated disposal location for recycling.
