Feature:1. Smart Shutdown: This meter has a smart shutdown function, which will automatically shut down after about 5 minutes of your non operation, which will greatly extend the battery life.2. DC Measurement: This meter can do DC measurement, so it can be used to determine the short circuit fault of electrolytic capacitors.3. Automatic Adjustment: Our meter can do automatic 0 adjustment at power on, and also do automatic 0 adjustment when switching between ESR and DCR. the LCD displays the ESR value and also the probe compensation value, so it is easy for users to adjust the 0 at the right time.4. Easy to Carry: Our meter is light weight and easy to carry, so you can carry it with you at any moment when you need to measure.5. High Accuracy: Our meter is made of ABS material with exquisite craftsmanship and high accuracy, which can achieve long term use.Specification:Item Type: ESR Capacitor TesterModel: ESR 2501CMaterial: ABSBattery Type: 14500 3.7V lithium battery x 1, shipping without batteryUse: Capacitance testingMeasurement Range: 0 to 25, divided into two grades 0 to 5 and 5 to 25, automatic switching.Resolution: 0 to 5 is 0.01, 5 to 25 is 0.1.Measurement Accuracy: 0 to 5, 1.5%+0.01. 5 to 25, 1.5%0.1..Package List:1 x Capacitor Tester(Shipping Without Battery)2 x Meter Pen(Red, Black)2 x Clips(Red, Black)4 x Gold Probe4 x Silver Probe1 x USB Power Cable
