They are easier to read.
The black probe is negative.
the multitester and its parts
And analog multi-tester will have a meter, battery, and switch. The meter is the part that can show the conversion of analog to digital or simply act as an analog display. The battery is the power source and the switch is the part that allows you to select the specific function of the multi-tester.
