Range and Accuracy Capacitor tester accuracy up to 1%. 0.01pF to 47,000nF (1%+2 digits, 0.2s to 1s); 47.00nF to 47,000uF (1% + 1 digit, 0.2s to 2s); 47.00uF to 470.00mF (1 to 3% + 1 digit, 0.2s to 30s) Stable Performance - More stable when reading (with auto-average function, pF can be read more stable and accurate). Reading 2200uF capacitance only takes ~0.2s. 5-Digit Display & Auto & Manual Modes Capacitor tester with 128 x 64 dot matrix LCD liquid crystal display that can display 5-digit readings. Auto and manual dual mode, providing more choices for measurement. New Version Test Leads - The auto-ranging capacitance meter comes with 2 test clips; The black pin is connected to the negative pole and the red test lead is connected to the positive pole. Suitable for DIY enthusiasts and professional engineers. Concealed Holder - Digital capacitor Equipped with a concealed holder, it is suitable for desktop testing and makes operation more convenient, suitable for professional engineers and DIY enthusiasts.
