17 Digital Voltmeter
The Digital Voltmeter (DVM) analysis feature provides 3-digit voltage and 5-digit 
frequency measurements using any analog channel. DVM measurements are 
asynchronous from the oscilloscope's acquisition system and are always 
acquiring.
The DVM display is a seven-segment readout like you would see on a digital 
voltmeter. It shows the selected mode as well as the units. Units are selected 
using the Units softkey in the Channel Probe menu.
After pressing the [Analyze] key, the DVM display also appears in the graticule 
along with a scale and the frequency counter value. The DVM scale is determined 
by the channel's vertical scale and reference level. The scale's blue triangle pointer 
shows the most recent measurement. The white bar above that shows the 
measurement extrema over the last 3 seconds.
