Mode) enters manual ranging and cycles through
"units/Div" scaling factors of 1, 2, and 4 for the
vertical axis, effectively zooming in and out on the
waveform display. The scaling factors divide the
units/Div for the present range. "Wave Scale" is not
available in Meter Mode.

effect. (You can also press r to return to the
previous softkeys.)

Touch Hold

This key allows you to hold a known good reading on
the display. (No special softkeys accompany Touch
Hold.) Use the following procedure:
h
1. Press H (
appears at top of the display.)
4-6
2. Apply measurement connections until you hear a
beep. This sound signifies that a stable reading
has been made. The display continues to update
with valid readings (and beeps) as long as you
maintain the measurement connections.
3. In Meter, Combo, and Trend display modes, the
last valid primary numeric reading is held; the
waveform in Combo and Trend is not held. In
View Mode and COMPONENT Test, the last
valid waveform is held.
Press H again to exit Touch Hold (
disappears.)
Touch Hold and "Peak Hold" are mutually exclusive:
activating one cancels the other. Touch Hold cannot
be activated when Frequency, SET UP, or LOGIC is
selected. Pressing F or d cancels Touch Hold.
Selecting "rms", "Average", or "Full Auto" cancels
Touch Hold. P stops Touch Hold display updates;
Touch Hold then continues to run in the background.
In view mode, selecting Touch Hold cancels "Glitch
Capture" and "Single Shot".
