Storage considerations
After the first charge, it is recommended that you fully
charge the battery periodically, even when it is not in use.
This is because the Ni- MH rechargeable battery pack may
drain with time.
Charging the battery
CAUTION
To avoid instrument damage from battery leakage:
• Always remove dead batteries immediately.
• It is recommended that the battery is removed and stored separately if
the multimeter is to be unused for long periods of time.
NOTE
The performance of the rechargeable battery may degrade with time.
WARNING
Never discharge the battery by shorting it or by reverse polarity in any
subjects. Make sure the battery is the rechargeable type before
charging it. Never rotate the rotary switch when the battery is being
charged as DC at 24 V is being applied to the charging terminals.
NOTE
For the battery charger, the mains supply voltage should not fluctuate by
plus or minus 10%.
