What is the meaning of the symbols on the multimeter?
Multi meter structure
1. A multimeter is mainly divided into two parts: the body and the pen. The pen is very simple, just two pens, a red pen and a black pen; The watch body includes a header or screen, a conversion knob, and a probe socket.
2. The top of the watch body is the display screen, which can show all the values we have measured.
3. Below the display screen are two buttons, namely the number retention button and the manual/automatic range button.
4. The middle part of the multimeter is the conversion knob, which is used to convert various gears. The characters on it represent the following meanings: starting from the OFF gear, they are AC voltage, DC voltage, DC voltage millivolts, Ω gear (resistance) and diode testing, capacitance, AC/DC ampere, AC/DC milliampere, and AC/DC microampere.
5. The bottom part of the multimeter body is the probe socket, with a total of four sockets from left to right, namely current ampere (note the current passing time requirement), current milliampere microampere (also note the current passing time requirement), COM (also known as common terminal), and voltage resistor diode; Insert black probes into the COM hole, and red probes into the other three holes.
6. Also, please note that the labeling method on each multimeter is different, but the meaning represented by the characters is consistent.
What do the symbols on a multimeter represent
1~
Expressing communication.
2. V-2.5KV 4000 Ω/V
The sensitivity for AC voltage and 2.5KV DC voltage is 4000 Ω/V.
3. A-V - Ω
Indicates measurable current, voltage, and resistance.
4. 45-65-1000Hz
The usage frequency range is below 1000 Hz, and the standard power frequency range is 45-65Hz.
5. 2000 Ω/V DC
The sensitivity of the DC gear is 2000 Ω/V, and the symbols on the clamp meter and rocker dial are similar to the above symbols.
