1.5 Battery handling
 When replacing battery cells or before opening battery/fuse compartment cover,
disconnect any test leads/accessory connected to the instrument and switch off the
instrument. Hazardous voltage can exist inside the instrument!
 Insert all cells correctly! If this is not performed correctly, the instrument will not
operate and the battery could be discharged.
 If the instrument is not used for a long period of time, remove all of the battery from
the battery compartment to protect the instrument from leakage.
 Alkaline or rechargeable 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 will begin charging as soon as the
power supply adapter is connected to the instrument. The in-built protection circuits
control the charging procedure.
