Internal Lithium-Ion Battery
• The battery is not charged upon purchase and must therefore be charged.
• The battery will be charged from power supplied through the USB cable
regardless of whether the instrument is turned ON or OFF.
• Charging should be performed at between 5°C and 40°C.
• The internal lithium-ion battery takes about 3 hours to become fully charged.
There is no need to worry about overcharging.
• The lithium-ion battery will self-discharge. The battery will become unusable
due to over discharging if left for a long period. Charge the battery at least
once every 6 months.
Notes on Storage
• The instrument should be stored at a temperature of between 0°C and 45°C
and a relative humidity of between 0% and 85% with no condensation.
Do not store the instrument in areas subject to high temperatures, high
humidity, or sudden changes in temperature, or in areas where freezing or
condensation may occur, as these circumstances may cause a malfunction.
We recommended storing the instrument with a drying agent at a
temperature of around 20°C.
• Do not leave the instrument inside a vehicle, such as in the cabin or the
trunk. Otherwise, the temperature and/or humidity may exceed the
allowable range for storage during midsummer or midwinter, resulting in a
malfunction.
• Do not store the instrument in areas where dust, cigarette smoke, or
chemical gases are present. Doing so may cause deterioration in
performance or a malfunction.
• Dust inside the limiting aperture (measuring port) may prevent accurate
measurements from being performed. When the instrument is not in use,
attach the calibration cap, and store the instrument in the standard
accessory soft case.
• The white calibration plate and ambient light adapter may become
discolored if left exposed to light. Therefore, make sure to store the
components in a location away from direct exposure to light when not in use.
• If the instrument will not be used for a long period of time, an auxiliary
charge is recommended once a year to protect the battery from
overdischarge.
