1.6 Changing or charging batteries
Mains adapter connection
If rechargeable batteries are used, you can charge them by connecting the delivered wall
adapter to the device and to an outlet. After 10 hours, the batteries will be charged completely.
The device should be switched off while the batteries are charged.
Caution:
-
pay attention to the polarity ( + / - ) when you place the batteries
-
only use 5 volts adapters (center terminal positive)
-
do not charge non-rechargeable batteries
-
used batteries should be handled as chemical waste
If you want to check if the batteries are being charged, then switch the device on. You will see
an animated picture of a battery that that is being filled. Then you can switch the device off
again. If you keep the meter on while the batteries are being charged, this will extend the
charging time, because a part of the charging current will be used to power the device.
When you change the batteries, then try to do that within one minute. After one minute, the
internal clock may lose the current time and date, and you will have to set these again.
Please be aware that most newly bought NiMH rechargeable batteries have to be charged
before the first use.
If you use ordinary (non-rechargeable) batteries, then Alkaline types are preferred.
The optional power adapter is suitable for mains voltages from at least 100 Volts up to 240
Volts AC.
