Item Type: Multimeter Material: ABS Product Model: for TY-360TRX Battery: 2 x 1.5V AA Batteries (Shipped Without Batteries) Steps: 1. Choose the right gear for the electric barrier. If the general capacity is less than 0.01uF, choose x10k gear. 1?10uF or so, choose X1k gear. Above 47uF, choose x100 block or x 10 block 2. After each test, short?circuit the capacitor with a wire, and then perform the following test after discharging. 3 Electrolytic capacitors have polarity, and the positive electrode has a higher potential than the negative electrode when in use. Since the black test lead is connected to the positive electrode of the battery in the meter, the black test lead is connected to the positive electrode of the electrolytic capacitor, and the red test lead is connected to the negative electrode of the capacitor. 4. A good capacitor performance is that the pointer deflects during detection, and then gradually returns to the mechanical 0 (that is, the resistance is infinite). 5. The deflection of the pointer is related to the electric capacity and the electric blocking position, and the deflection is large when the capacity is large. 6. Pay attention to laws and accumulate data in practice 7. The performance of a capacitor that loses capacity is that the detection pointer does not deflect, and no discharge is required. If the test pen is quickly exchanged, the pointer does not deflect. 8. The performance of the capacitor that has lost part of the capacity is that compared with the standard capacitor, the pointer deflection is not in place. You can use experience or refer to the standard capacitor of the same capacity to determine the maximum amplitude of the pointer swing 1High Definition Scale: The multimeter has high definition scale, clear writing, no ghosting, easy to read and easy to use. 2Multiple Measuring Ranges: Using sophisticated production technology, the multimeter has multiple measurement ranges and multiple measurement options. 3No Slipping: Made of high quality materials, the multimeter has a strong sense of pause between pulls and does not slip. 4Humanized Design: The multimeter adopts a humanized design, equipped with a back support frame, beautiful appearance, small and meticulous, and comfortable to hold. 5With fine workmanship, the multimeter is integrated with multiple protection circuit boards, which is safe and practical to use.Shipped Without Batteries1 x Multimeter 2 xMeter Pen
