2.5 Loading, Removing, and Charging the Battery Pack
Loading the Battery Pack
1.
Align the battery pack terminal with the battery pack cover terminal, and place the battery pack
on the battery pack cover.
Gently push the battery pack so that the terminals become securely connected.
2.
Load the battery pack cover into the instrument by reversing the procedure for removing the
battery pack.
3.
Check that the battery pack cover is not loose, and then fasten the attachment screws with a
flat-bladed screwdriver.
Tightening torque: About 0.6 N•m
Note
Pressing the battery pack’s TEST button turns on the indicator that shows the battery level; this is not a
malfunction. The indicator will turn off after a while.
Over Discharge and Long Periods of Storage
• If you do not use the instrument for an extended period of time with the battery pack connected to the
instrument, the battery pack may become over discharged. This shortens the service life of the battery
pack. To avoid over discharging, if you will not use the instrument for one week or longer, charge the
battery pack, remove it from the instrument, and store the battery pack in a cool place (10°C to 30°C)
away from direct sunlight.
• When you store the battery pack for six months or longer, to replenish the power that is lost through self-
discharge, recharge the battery using the instrument once every six months.
• Avoid storing the battery pack for an extended period of time when it is fully charged (after it has just been
charged) or when it has no power left (when the instrument will not turn on). Storing the battery pack
under these conditions will degrade its performance and reduce its longevity. It is best to store the battery
back when it is 40% to 50% charged. This is equivalent to the state the battery is in after you turn off the
instrument and charge an empty battery for about 2.5 hours at room temperature.
• Charge the battery pack prior to its first use or if it has not been used for an extended period of time.
Charging the Battery
To charge the battery, connect the AC adapter or DC power cable to the instrument. For details, see
sections 2.6 and 2.7.
• The charge time is about 6 hours if the battery is charged with the power turned off.
• The charge time may exceed 15 hours if the battery is charged with the power turned on.
CAUTION
If battery charging does not complete within 6 hours with the power turned off, stop
immediately. The battery pack may be malfunctioning. Do not use the battery pack, and
contact your nearest YOKOGAWA dealer.
