Item Type: ESR Tester <br>Material: ABS <br>Measuring Range: 0-25Ω, divided into 0-5Ω and 5-25Ω, automatically switching <br>Resolution: 0-5Ω: 0.01Ω, 5-25Ω: 0.1Ω <br>Measurement Accuracy: 0-5Ω: ±1.5%±0.01Ω, 5-25Ω: 1.5%±0.1Ω <br>Battery Specifications: 1 x 14500 (not included)1、Scope of Application: ESR capacitor meter can measure electrolytic capacitance as well as DcR (DC resistance), which is switched by ON OFF ZERO button. <br>2、Synchronous Detection of Short Circuits: ESR capacitance tester adopts synchronized detector short circuit, so the test value is the real ESR. <br>3、High Accuracy: ESR tester is capable of both on circuit and off circuit measurements, with a measurement current of 5mA and a measurement frequency of 100kHz, which is the industry standard for ESR measurements. <br>4、Automatic Zero Adjustment: Power on automatic zero adjustment, ESR and DCR switching also do automatic zero adjustment. LCD in the display of ESR value at the same time, but also the probe compensation value is displayed, so that users can adjust the zero to ensure the highest accuracy at the right time. <br>5、Smart Shutdown Function: The input terminal has over voltage protection, manual and automatic shutdown function, about 5 minutes of non use will automatically shut down. When the power supply voltage is too low, the LCD will prompt and it will shut down automatically after 10 seconds.<p>1 x ESR Tester<br>1 x Instruction Manual<br>2 x Clips<br>1 x Connectable Meter Pen<br>8 x Replacement Needles<br>1 x USB Cable</p>
