How to repair the detachment of the multimeter wire and probe
1. The red and black pen of the multimeter is on the plug, which can be easily pulled out. A metal male socket is connected to a leather wire, and because the connection point of this wire post is easy to break, I tell you that my pen wire is much shorter and has been repaired multiple times, wasting 1 centimeter each time. I have removed and repaired the wire of both types of watches (electronic and pointer), and the wire joint of the pointer watch is easier to repair. Just unscrew the threaded red plastic upper sleeve, Clamp the metal pile onto a vise, melt the solder wire with a soldering iron, and then peel off half a centimeter of the leather wire to expose the copper wire. Melt it with tin, and it is best to put an insulated wax tube on the wire, so that the outer sleeve is not easily broken after welding.
2. The wire stakes of a digital meter are not very easy to weld. The plastic sleeve is large and hard. You need to pull it out first, thread the wire in, weld it on the outside, and then return it to its original position. If you don't even have welding skills, it's difficult to do it!
The red pen pile head above is a plastic sleeve that has been repaired and then ironed with a soldering iron to secure the crack.
Those who can own and use a multimeter will have a certain understanding and contact with radio and electrical appliances for maintenance. They will inevitably use an electric soldering iron, which can be disassembled using soldering tin.
primary uses
A multimeter can not only be used to measure the resistance of the object being measured,
AC and DC voltage can also be measured for DC voltage. Some multimeters can even measure the main parameters of transistors and the capacitance of capacitors. Fully mastering the use of a multimeter is one of the most basic skills in electronic technology. Common multimeter types include pointer type multimeter and digital multimeter.
A pointer type multimeter is a multifunctional measuring instrument with a meter head as the core component, and the measured value is read by the pointer of the meter head. The measured values of a digital multimeter are directly displayed in digital form on the LCD screen, making it easy to read. Some also have voice prompts. A multimeter is a common meter that integrates a voltmeter, ammeter, and ohmmeter.
The DC current range of a multimeter is a multi range DC voltmeter. The parallel connection of the meter head with a closed circuit voltage divider resistor can expand its voltage range. The DC voltage range of a multimeter is a multi range DC voltmeter. The voltage range can be expanded by connecting the meter head in series with a voltage divider resistor. The corresponding range varies depending on the voltage divider resistance. The head of a multimeter is a magnetoelectric measurement system, which can only measure AC power through DC, using a diode to convert AC into DC.
