Observe the following to avoid damage to the instrument.
• Use the battery pack in an ambient temperature range of 0 to
40°C and charge it in an ambient temperature range of 5 to 30°C
to be on the safe side.
• If the battery packs fails to complete charging within the stipu-
lated time, disconnect the AC adapter from the pack to stop
charging.
• Consult your dealer or nearest service station should liquid
leaks, strange odor, heat, discoloration, deformation and other
abnormal conditions occur during use, charging or storage.
Should these conditions occur during use or charging, turn off
and disconnect the instrument immediately.
• Do not expose the instrument to water and do not use it in exces-
sively humid locations or locations exposed to rain.
• Do not expose the instrument to strong impacts and do not throw
it around.
• The battery pack is subject to self-discharge. Be sure to charge
the battery pack before initial use.
• When recharging a discharged battery pack in the LR8431-20,
allow it to charge for at least ten minutes with the LR8431-20
turned off to maximize battery longevity.
• The battery pack is a consumable. If the battery capacity remains
very low after correct recharging, the useful battery life is at an
end. It can be recharged up to about 500 times.
• To prevent battery pack deterioration when the battery will not be
used for 1 month or longer, remove it and store it in a dry location
with an ambient temperature range of between -10 to 30°C. Be
sure to discharge and charge it every two months. Long-term
storage when capacity has decreased will make charging impos-
sible and reduce performance.
• Remove the battery pack from instrument once a month and
check that appearance is normal.
• As long as battery charge remains, waveform data is retained in
internal memory while the Memory HiLogger is turned off, so the
battery continues to gradually discharge. When the battery
charge is depleted, stored waveform data is lost.
