How to measure frequency

  • The next two steps explain how to measure frequency with your multimeter.

  • The frequency functionality measures the dominant frequency in an AC circuit. If the circuit has complex AC signals or noisy signals, the multimeter may not measure the frequency accurately.

  • Plug the black lead into the COM port. Plug the red lead into the right port.

  • Switch the multimeter to the AC Hz mode:

  • Turn the function dial to the Volts mode.

  • Press the blue Select button to switch to AC volts.

  • Press the Hz button to toggle the frequency measurement mode.

如何测量频率

接下来的两个步骤说明如何使用你的万用表测量频率。

频率功能用于测量交流电路中的主导频率。如果电路中存在复杂的交流信号或噪声信号，万用表可能无法准确测量频率。

将黑色表笔插入 COM 端口，将红色表笔插入右侧端口。

将万用表切换到 AC Hz 模式：

将功能旋钮转到伏特模式。

按下蓝色 Select 按钮切换到交流电压模式。

按下 Hz 按钮以切换到频率测量模式。
