AINS POWER SUPPLY
The meter is provided with a pack of
4 x 1.2V-2200mA/h Ni-MH rechargeable batteries
, placed
in the battery compartment.
The battery symbol on the display constantly shows the battery charge status. To the extent
that batteries have discharged, the symbol "empties". When the charge decreases still further it
starts blinking.
In this case, batteries should be replaced as soon as possible.
If you continue to use it, the instrument can no longer ensure correct measurement and turns
off.
Data stored on memory will remain.
The battery symbol becomes
[

]
when the external power supply is connected and the
batteries charging process is ended.
