Today I will introduce to you how to measure DC voltage, AC voltage and resistance with digital f15b.

First, let me introduce to you how to use f15b to measure a 9v battery.

The first step: Insert the test leads correctly. This was introduced to you last time and will not be repeated here.

Step 2: Turn the multimeter's rotary switch to the DC voltage position.

Step 3: Use the other end of the test lead to match the positive and negative poles of the 9v battery.

Step 4: The reading of the digital multimeter is the DC voltage of the 9v battery.

Next, I will introduce to you how to measure AC voltage.

Step 1: Insert the test leads correctly.

Step 2: Rotate the rotary switch to the AC voltage position.

Step 3: As shown in the picture: insert the test leads.

Step 4: The reading of the multimeter is the AC voltage.

Finally, I will introduce to you how to use a multimeter to measure resistance.

The first step: The steps are the same as measuring DC and AC voltage, except that the rotary switch must be rotated to the corresponding resistance position. Take a look at the picture below, I believe you have learned it.
