7.7 How to Measure Depth, Time Between Locations
You can measure the depth to an object with the VRM. Also, you can measure the time
from the right edge to a location. For example, you can measure how many minutes
ago an echo appeared.
To measure the depth or the time to a location, operate the CursorPad to put the VRM
on the object to measure depth or time. Read the depth below the VRM and the time
at the top of the screen.
The VRM cannot be operated when the Gain adjustment window is active.
