Digits of the multimeter
The multimeter belongs to low frequency (<1MHZ), and it is mostly used for DC and precision measurement (higher precision than oscilloscope, but lower sampling rate). That is, the effective resolution. The multimeter with the same number of digits has different counter number ranges, and the resolution is also different).
For example, the same 5 and a half digits, the count is 240000, for example, the 2V gear, considering the over-range, in fact, the gear can be measured to 2.39999V, that is, each count corresponds to 0.00001V, that is, 10uV, that is to say, the count number is a full How many parts can the range be divided into? It is also 5 and a half digits. If it is 120000 count, the range is still 0~2.4V. Obviously, each part is 20uV, which means that the effective resolution can only reach 20uV, which is also 5 and a half digits. There are specific differences in the specifications of these two multimeters, so the more count digits, the more accurate.
