What are the difference of use of digital multimeter and pointer multimeter.?

1.Comparison of the use of digital multimeter and pointer multimeter.  

First, pointer multimeter.

In order to improve the detection accuracy, the other parameters are detected by adjusting the baffle switch to make the pointer indicate the detection data at 1 / 2 ~1 / 3 in order to reduce the detection error. When making the electric barrier, first select the detection baffle, then adjust the zero position of the pointer, and then multiply the test result by the range multiplier.

Second, digital multimeter.

In the detection process of digital multimeter, in order to improve the resolution, the selection of the baffle switch is to make the display full position. At the same time, the digital multimeter in the case of excess range, there will be a prompt on the display information, resistance reading and other quantities of the detection of the same direct reading.

2.The operating before and after the measurement.

First, before measurement.

In the use of digital multimeter, first turn on its power switch to the ON position, so that the display screen has a digital display.

Second, after measurement.

After the end of the digital multimeter measurement, the power supply should be switched off in time, that is, the power switch should be set to the OFF position. For a digital multimeter that has been used for a long time, the dry battery inside it should be removed.
