6. Priežiūra

6.1 Įkrovimas

The multimeter is equipped with a built-in USB rechargeable lithium battery. Recharge the device when the battery indicator shows low power. Use the provided USB cable for charging.

6.2 Valymas ir laikymas

Clean the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Store the multimeter in its protective bag in a cool, dry place away from direct sunlight and extreme temperatures when not in use.

7. Problemų sprendimas

• Ekrano įskaitomumas saulės šviesoje: The display may be difficult to read in direct sunlight. Adjust the angle of the device for better visibility.
• Temperatūros vienetas: The device displays temperature in Celsius only. There is no option to change this to Fahrenheit.
• Current Measurement Ports: The included manual may contain inaccuracies regarding the correct ports for current measurement. Always use the dedicated Amperage (A) port for current measurements, not the VΩHz port, to avoid damage to the device or inaccurate readings.
• Tęstinumo pyptelėjimas: The continuity test features an audible beeper. There is no function to disable this beeper.
• Tikslumas: Readings may show slight variations compared to higher-end or calibrated testers. For critical applications, verify readings with a known accurate device.
• Ekrano išjungimo režimas: The 'screen off' function only turns off the display backlight to save battery, the device remains operational.
