How to use a desktop multimeter
The use of desktop multimeters is relatively different than that of mobile multimeters, but the basic principles are the same. The use of the desktop multimeter is also very simple. First of all, the desktop multimeter has a red contact derived from a red test pen, and a black contact derived from a black test pen, which has the same meaning as the general multimeter. The red test pen represents the positive pole. The black test pen represents the negative pole.
Then, before using the desktop multimeter, the mechanical zero adjustment is the first step, and it is also a step that cannot be omitted. After that, according to the measured power consumption parameters of the device, if we measure the DC voltage here, the knob of the desktop multimeter at this time is turned to the DC voltage column, and the voltage or resistance or AC voltage cannot be wrongly entered. Column, and finally contact according to the red and black test pens.
