The second-line resistance is 32 kilohms, the third-line 100 kilohms
Dimensions: 30*11.5*9MM
Installation opening: 23*10MM
Line length: 15CM
The second line does not require external power supply and has no working voltage
2-wire detection voltage: 2.5-32V (with reverse connection protection function)
Will it burn if I connect the wrong cable? Answer: No, it is protected against reverse connection
0.28 How much is this A? Answer: This has nothing to do with current. Voltmeter has nothing to do with current and power.
·Feature description
1. The wiring of this voltmeter is simple. Two wires are conventionally used. Red connects positive and black connects negative. There is reverse connection protection inside, and it will not burn if connected reversely.
2. No external power supply is required for normal operation, and it can work directly with measuring voltage. The measuring voltage range is 2.4-30V.
3. Wide voltage operation, the red minimum measurement voltage is 2.4V, and the maximum safe bearing voltage can reach 40V. If it exceeds 40V, it may be damaged.
4. When measuring voltage below 10V, two digits after the decimal point, when measuring voltage above 10V, one digit after the decimal point.
5. For other requirements or test ranges [three-wire 0-100V, please take other product links].

Measuring accuracy, this voltmeter will automatically move the position of the decimal point according to the measured voltage.
When measuring voltage below 10V, two digits will be displayed after the decimal point,
When measuring voltage greater than 10V, one digit after the decimal point is displayed.
It can not only take care of the battery user's need for measurement accuracy, but also take care of the need for measuring higher voltages.
This voltmeter can be used to measure the voltage of 18650 batteries, mobile phone lithium batteries, Ni-MH battery packs and other battery packs.
As well as the battery voltage of motorcycles and automobiles, it can also be used for other voltage measurement purposes
