3.3 Use of external power
The instrument comes standard with a power adapter.
In addition to supplying power to the instrument, this power supply also charges the lithium battery
inside the instrument, so the power adapter cannot be replaced. It is recommended to use our
company's special power supply.
Figure 3-2 Connecting the external power adapter to the instrument.
Plug the power adapter into the AC adapter input jack on the instrument.
3.3.1 Battery charging function
If the battery is not fully charged, the instrument's charging circuit will automatically start to charge
the internal lithium battery after the power adapter is plugged in. The instrument's built-in indicator
of the power switch key will light up to indicate that charging is in progress. This indicator will
remain lit even after the instrument is turned off, until it goes out when the battery is fully charged.
