4. Configuració

4.1 Càrrega inicial

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 Encès/Apagat

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. Instruccions de funcionament

The AUTOOL DM103 offers six primary test modes for various component measurements.

Figura 7: Six Test Modes. This diagram outlines the different measurement capabilities of the device.

5.1 General Measurement Procedure

1. Power on the DM103.
2. Select the desired test mode using the 'MODE' button.
3. Carefully grip the component with the gold-plated tweezers. Ensure good contact with both leads of the component.
4. Read the measurement results displayed on the OLED screen.
5. To freeze the display, press the 'HOLD' button. Press again to release.

5.2 Modes de prova

• Mode automàtic: Automatically recognizes L/C/R and determines the condition of components. This is the default and most convenient mode for general testing.
• Inductance Mode: Measures inductance from 1µH to 60H, suitable for high-frequency, low-power to low-frequency, high-power scenarios.
• Capacitance Mode: Measures capacitance from 1pF to 20mF, suitable for all scenarios from high-frequency signals to power filtering.
• Mode de resistència: Measures resistance from 10mΩ to 10MΩ, providing precise measurements for various resistors.
• Diode Mode: Automatically detects diode polarity and measures forward voltage gota.
• Continuity Mode: Automatically beeps to indicate the circuit's continuity status, enabling quick fault diagnosis.

6. Manteniment

6.1 Neteja

Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the gold-plated contacts are clean for accurate measurements.

6.2 Emmagatzematge

Store the DM103 in its protective carrying case when not in use. Keep it in a cool, dry place, away from direct sunlight and extreme temperatures. The recommended storage environment is Temperature -20°C to 60°C, Humidity <80%.

6.3 Cura de la bateria

To prolong battery life, avoid fully discharging the battery frequently. If storing for extended periods, charge the device to approximately 50% every few months.

7. Solució De Problemes

• El dispositiu no s'encén: Ensure the battery is charged. Connect to a USB-C charger and try again.
• Lectures inexactes:
  • Ensure the component is fully discharged and powered off.
  • Check for good contact between the tweezers and the component leads.
  • Clean the gold-plated contacts if dirty.
  • Ensure the correct test mode is selected, or use Automatic Mode.
• Screen is dim or unresponsive: Adjust backlight brightness in settings. If unresponsive, try restarting the device.
