3.1 Power Supply
3.1.1 Battery
KEW6305 operates with either an AC power supply or batteries.
Capable of performing measurements in the event of AC power interruption, power to the instrument
is automatically restored by the batteries installed in the instrument. Dry-cell batteries (alkaline) and
rechargeable batteries (Ni-MH) can be both used.
* Dry-cell batteries (alkaline) are supplied as accessories.
DANGER
● Never open the Battery Cover during a measurement.
● Brand and type of the batteries to be used should be harmonized.
● Never touch the Power supply connector although it is insulated while the instrument is operating with
batteries.
WARNING
● Ensure that the Power cord, Voltage test leads and Clamp sensor are removed from the instrument,
and that the instrument is switched off when opening the Battery cover for battery replacement.
CAUTION
● Never mix new and old batteries.
● Install batteries in correct polarity as marked inside the Battery compartment area.
Batteries are not in the instrument at the time of purchase. Please insert the supplied batteries before
starting to use the instrument. Battery power is consumed even if the instrument is being off. Remove all
the batteries if the instrument is to be stored and will not be in use for a long period.
When the instrument is powered by an AC power supply, it doesn’t operate with batteries.
If an AC supply is interrupted and the batteries have not been inserted, the instrument goes off
and all data may lost.
