Measuring range
In a multi-function digital multimeter, different functions have their corresponding maximum and minimum values that can be measured.
Measuring rate
The number of times a digital multimeter measures the measured electricity per second is called the measurement rate, and its unit is "times/s". It mainly depends on the conversion rate of the A/D converter. Some handheld digital multimeters use the measurement period to indicate the speed of measurement. The time required to complete a measurement process is called the measurement cycle.
There is a contradiction between the measurement rate and the accuracy index. Usually, the higher the accuracy is, the lower the measurement rate is, and it is difficult to balance the two. To solve this contradiction, you can set different display digits or set the measurement speed conversion switch in the same multimeter: add a fast measurement file, which is used for the A/D converter with a faster measurement rate; To increase the measurement rate, this method is relatively common and can meet the needs of different users for the measurement rate.
