Charging
The new machine is not fully charged after it left the factory. A full charge
is recommended before first use. Connect one end of the USB charging cable
to the charger, and the other end of the micro USB to the USB charging port
of KN-201, then plug the charger into an AC110/220V socket. When orange
light shows up, indicates charging is in progress; and green light indicates
charging is complete. It takes about 3 hours to get fully charged when the
battery is completely discharged. It can be powered on continuously for 8
hours after a fully charge.
When charging in the power-on state, a plug symbol with the word C
appears on the upper right hand corner of the display screen. The C word will
be replaced with a simple plug symbol when fully charged. When the
equipment is turned off, tap on any key to wake up the display. If the screen
displays "Battery Charging", indicates that charging is in progress. When
showing "Full Charged", means the battery is fully charged and the charging
will automatically stop. This product supports charging and operating the
measurement work at the same time.
When the battery is completely discharged, "battery Empty" is
displayed and the equipment will shut down automatically. It is
recommended to plug in the charger to charge the battery before using the
equipment to avoid damaging the battery.
If the product is not frequently used, we recommend charging the
battery at least once a month, to avoid damaging the lithium battery due to
low battery voltage.
