4. Орнотуу
4.1 Алгачкы заряддоо
Before first use, fully charge the AUTOOL DM103. Connect the provided USB-C cable to the device's charging port and plug the other end into a standard USB power adapter (not included) or a computer's USB port. The charging indicator on the screen will show the charging status. A full charge typically takes a few hours.
4.2 Күйгүзүү/өчүрүү
To power on the device, press and hold the power button (usually labeled 'MODE' or a dedicated power symbol) for a few seconds until the screen illuminates. To power off, press and hold the same button until the screen turns off. The device also features an adjustable auto-power-off function (5 minutes to 120 minutes) to conserve battery life.
5. Иштөө нускамалары
The AUTOOL DM103 offers six primary test modes for various component measurements.
