Fluke 105B - Using Zoom to Increase or Decrease Time Resolution

Using in Scope Mode 5 - 9
Using "Zoom" to Increase or Decrease Time Resolution
Zoom displays a waveform with increased time resolution,
giving up to 1000x magnification. Use the following
procedure to Zoom in a waveform:
1. Press
2. Use the and keys to highlight "scope
zoom".
3. Press to select. appears in the right
bottom of the display.
4. Press to enlarge the waveform (speed up the
time base) or press to shrink the waveform (slow
down the time base).
The ScopeMeter test tool zooms in and out one step at a
time and, if necessary, the trigger delay is recalculated.
The focal point for this activity is waveform activity at the
fourth time division. The zoom feature is useful as a quick
examination of a live waveform. Zoom cannot be used on
saved waveforms recalled from memory or when the
waveform is frozen (HOLD).
