ترجمه متن پشتش شاید بدرد کسی بخوره manual Range of use: 12-250VAC/12-250V.DC/0-10MS2 Instructions for use: 1. AC power test: Touch the direct test button with your hand and measure the charged body with a pen. If there is a digital display, it is the live wire, otherwise it is the neutral wire. 2. Estimate the zero live wire and breakpoint outside the line: touch the detection button by hand, measure the insulation layer of the charged body with a pen, if there is a symbol, it will be displayed as the live wire, otherwise it will be the neutral wire; move along the line and the symbol disappears to the position of the breakpoint of the wire. 3. To test whether the electrical equipment is on or off (it cannot be measured with power on); touch one end of the device under test and measure the other end. If the light is on, the device is on, otherwise it is off. 4. Measure the battery capacity: touch the positive pole of the battery with your hand, and measure the positive pole with the tip of the pen. 5. Test electronic components: 1. Measure small capacitors: touch one pole with your hand, measure the other pole to flash for a while, which means the capacitor is normal, and measure the position of the reverse position as above. open circuit. 2. Diode measurement: touch one pole with your hand, and measure the light of the other pole. If you touch the pole with your hand, it will be the positive pole, otherwise it will be the negative pole. If both directions are on or not on, it means short circuit or open circuit. 3. Test the triode: Touch one pole with your hand in turn, measure the other two poles respectively, until it is fully lit, the hand touches the very base, and the triode is NPN type. Measure one pole, touch the other two poles, the light is measured as the base pole, the triode is PNP type. Note: If the self-test fails, open the back cover to check whether the contact is good. The main function ▲Contact electric test, intuitive display.
