[Wide use]: This meter can test resistance, capacitance, battery, diode, Zener and continuity. [Easy to carry]: The capacitance tester is a small hand-held battery-powered SMD (surface mount device) measuring tool, equipped with a carrying case, which is easy to carry. [Zener test]: The open circuit voltage is higher than DC 20V [High Quality]: The capacitance tester is brand new and high quality. [Auto-off]: Large LCD display, if you don't press the button during this period, it will automatically turn off after 15 minutes. Resistance: 400 ohm~40M ohm Capacitance: 4nF~200uF Display: 4000counts Range selection: automatic Specification: Resistance: 400 ohm/6K ohm/40K/400K ohm +/- 2.0%rdg; 4M ohm/40M ohm +/- 2.5%rdg Capacitance: 4nF/40nF/400nF/4F +/- 2.5%rdg; 200F +/- 3.0%rdg Diode test: open circuit voltage: 1.5V, test current: 2mA Continuity check: When the resistance is less than about 30 ohm, the buzzer will sound.
