Easy to operate: The capacitor esr dcr tester features a user-friendly interface and control system, making it simple and convenient to operate. 4. Reliable results: The test in circuit capacitance meter provides reliable and consistent measurement results, ensuring accurate analysis of capacitor performance. 5. Versatile functionality: The test in circuit capacitance meter offers additional features such as capacitance measurement and temperature compensation, enhancing its versatility for various testing needs.<br><br>1. The measuring range is 0-25Ω, divided into 0-5Ω and 5-25Ω, and it switches automatically. 2. Resolution: 0-5Ω is 0.01Ω, 5-25Ω is 0.1Ω. 3. Measurement accuracy: 0-5Ω range ±1.5%±0.01Ω, 5-25Ω range ±1.5%±0.1Ω. 4. It can measure the ESR of electrolytic capacitors and DCR (DC resistance), which can be switched by ON/OFF/ZERO button. 5. Short circuit uses synchronous detection, so the detected value is the real ESR. 6. It can measure online and offline, the measuring current is 5mA, and the measuring frequency is the ESR measurement industry standard frequency of 100kHz. 7. Automatic zero adjustment when power on, and automatic zero adjustment when ESR and DCR are switched. The LCD displays the ESR value and the probe compensation value at the same time, which is convenient for users to adjust zero in time to ensure the highest accuracy. 8. The input end has overvoltage protection. 9. Manual and automatic shutdown functions. Automatic shutdown is an intelligent way. It will automatically shut down if not used for about 5 minutes. 10.When the power supply voltage is too low, the LCD screen will prompt and it will automatically shut down after 10 seconds. note:
