The AUTOOL Digital LCR Tweezer, No. DM103, is a multifunctional portable LCR tweezer with a measurement accuracy of + or - 0.5 percent. 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.
