The new ESR2501C Capacitor ESR DCR Tester is a device used to test the Equivalent Series Resistance (ESR) and Direct Current Resistance (DCR) of capacitors. It can also measure capacitance in circuit and includes test leads with battery clips for easy connection. This portable tester is ideal for identifying faulty capacitors in electronic circuits quickly and accurately. It is a valuable tool for technicians and hobbyists working with electronic components, ensuring efficient troubleshooting and maintenance of electronic devices.
1. The measuring range is 0-25Ω, divided into two gears: 0-5Ω and 5-25Ω, automatically switched.
2. Résolution: 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 the electrolytic capacitor, and also measure the DCR (direct current resistance), which can be switched by the ON/OFF/ZERO button.
5. The synchronous detection is used for short circuit, so the tested value is the real ESR.
6. It can be measured in-circuit and off-circuit, the measuring current is 5mA, and the measuring frequency is ESR measuring industry standard frequency 100kHz.
7. Automatic zero point adjustment at power-on, automatic zero point adjustment is also done when ESR and DCR are switched. While the LCD displays the ESR value, it also displays the probe compensation value, which is convenient for the user to adjust the zero in time to ensure the highest accuracy.
8. The input terminal has overvoltage protection.
9. Manual and automatic shutdown functions, automatic shutdown is an intelligent way, and it will automatically shutdown if it is not used for about 5 minutes.
10. When the power supply voltage is too low, the LCD will prompt and it will automatically shut down after 10 seconds.
11. Use a 3.7V 14500 lithium rechargeable battery, which can be charged while using it. The charging power supply is DC5-6V, and there is a charging indicator on the left, which is red when charging, and green after charging. The charging time is 2-3 hours.
12. The maximum working current of the whole machine is about 60mA (3.7V).
13. Dimensions: 125x80x32mm.
14. Poids: à propos 200 g
15. Température de travail: 10-40℃
