How to use a dial multimeter to calculate voltage measurements
Pointer multimeter generally has 4-5 scales, respectively resistance scale, voltage scale, current scale, decibel scale, and there is a special scale for AC 1OV, which is readable at 1OV, voltage scale is divided into AC and DC scales, and part of the table also has AC current scale, and DC voltage scale, such as DC voltage scale (MF-10 type) has 1V2.5V10∨50∨100V250V500V, DC voltage scale has O-5O numbers. 100V250V500V, DC voltage scale has O-5O numbers, when the range switch is set to 50V for direct reading, range switch in 1V when the indicated value multiplied by 0.02 for the actual value, 10V multiplied by 0.2, 100V multiplied by 2, that is, the full scale for 1v, 10V and 100V. when the range switch is set to 2.5V, 250 when the indicated value multiplied by 0.05 and 5 for the actual value. Actual value. When the range switch is set to 500, multiply by 10. The same applies to AC voltage.
When you measure the voltage will choose a different gear to measure, when the meter pointer in a certain value to stabilise and not in the swing when you read out the numerical value multiplied by the multiplication of the gear you use is the actual value of the voltage measured by the multimeter.
