Digital Voltmeter (DVM) and Frequency
Counter
This series oscilloscope provides a built-in digital voltmeter (DVM) and frequency
counter, which enable you to perform an accurate measurement, improving user
experience in counter and frequency measurement.
10.1 Digital Voltmeter (DVM)
The built-in DVM of this oscilloscope provides 3-digit voltage measurements on any
analog channel. DVM measurements are asynchronous from the oscilloscope's
acquisition system and are always acquiring.
Press > Analyze > DVM to open the DVM setting menu, or enable the touch
screen and then tap the function navigation icon at the lower-left corner of the
screen to open the function navigation. Then, tap the "DVM" icon to open the DVM
setting menu. You can also press > Add, then in the displayed measurement
category area, rotate the multifunction knob to select "Analyze", and then select
"DVM" to open the DVM setting menu.
10.1.1 To Enable or Disable DVM Measurement
In the "DVM" setting menu, press the DVM continuously to enable or disable DVM
measurement. When enabled, the following figure is displayed. The DVM display also
has a scale that is determined by the channel's vertical scale and vertical offset. The
scale range is the range of the screen. The scale's yellow triangle pointer shows the
most recent measurement result. The specific value above the pointer shows the
measurement extrema over the last 3 seconds.
