Battery level indicator
• Charging takes about 5 hours with the power turned off. If the instrument is charged with the power turned on, it may take longer
than 15 hours, but charging will be suspended after about 15 hours by the protection circuit. If battery charging does not complete
within 8 hours with the power turned off, stop immediately. The battery in the instrument may be malfunctioning. Contact your nearest
YOKOGAWA dealer.
Note
Over Discharge and Long Periods of Storage
• If you do not use the instrument for an extended period of time, the battery in the instrument may become over discharged. This
shortens the service life of the battery. To prevent over discharging, charge the instrument once a month.
• Charge the instrument prior to its first use or if it has not been used for an extended period of time.
