In automotive circuit board testing, the loss factor D value is a key indicator reflecting the performance of capacitors. A smaller D value indicates lower loss and better component performance, while a larger D value suggests higher loss, which may indicate aging, damage, or quality issues. Traditional digital or needle-type multimeters can only measure the capacitance in a static state and cannot test key parameters such as the D value (loss factor) and Q value (quality factor). This may lead to misjudgments, increasing repair time and costs.
The AUTOOL DM103 is a multifunctional portable LCR tweezer with a measurement accuracy of ±0.5%. It features a HD OLED color display and supports precise measurements of resistance, capacitance, inductance, and diode/continuity. It offers three testing frequencies: 100Hz, 1kHz, and 10kHz, with the option to choose between 0.3V or 0.6Vrms effective test levels. During measurement, it can synchronously display both primary and secondary parameters. The secondary parameters include RS, D, Q, Z, and X values, meeting various component testing needs.
