10. Consells d'usuari

• For accurate current measurements, ensure only one conductor passes through the clamp jaw. Measuring multiple conductors will result in a zero reading if currents are balanced.
• When measuring resistance or capacitance, always ensure the circuit or component is completely de-energized and discharged to prevent damage to the meter or inaccurate readings.
• The True RMS feature provides accurate readings for non-sinusoidal AC waveforms, which is common in modern electronics.
• Utilize the backlight function in dimly lit areas for better visibility of the display.
