1.2 Battery handling
•
When battery cells have to be replaced or before opening battery/fuse
compartment cover, disconnect any measuring accessory connected to the
instrument and power off the instrument, hazardous voltage inside!
•
Insert cells correctly, otherwise the instrument will not operate and the battery could
be discharged.
•
If the instrument is not used for a long period of time remove the battery from its
compartment.
•
Alkaline or rechargeable Ni-Cd or Ni-MH battery cells (size AA) can be used. The
operating hours are given for cells with a nominal capacity of 2100 mAh.
•
Do not recharge alkaline battery cells!
The battery is charged whenever the power supply adapter is connected to the instrument.
In-built protection circuits control the charging procedure and assure maximal battery
lifetime. Power supply socket polarity is shown in the figure below.
