ESR02 Pro Digital Transistor Tester, Multi-Function ESR Meter & Capacitor Tester for Resistor Inductor Diode Triode Component Tester, Automatic SMD Detection, Backlit LCD Display

Important NotesSAFETY FIRST: Always fully discharge capacitors before testing. Failure to do so may cause permanent damage to the transistor tester’s internal circuitry.POWER MANAGEMENT: The device is powered by a 9V battery (not included). When the battery power drops below 6V, please replace it with a new one to ensure accurate measurements. The Transistor tester esr meter can also be powered by a DC 9V-12V adapter (not included).SpecificationsModel: ESR02 ProResistor Range: 0Ω - 50MΩ (Resolution: 0.01Ω)Capacitor Range: 25pF - 100mF (Resolution: 1pF)Inductor Range: 0.01mH - 20H (Resolution: 0.01mH)Capacitor ESR Resolution: 0.01ΩDisplay: Backlit LCD ScreenPower Supply: 1 x 9V 6LR61 Battery (not included)Dimensions: 14 x 8 x 4.5 cm / 5.5 x 3.1 x 1.8 inchesWeight: Approx. 214g / 7.5ozWhat’s in the Box?1 x ESR02 Pro Transistor Tester1 x Pair of Test Clip Leads for SMD Components1 x User Manual
