AUTO SCALE For the selected trace (data trace/memory trace of trace A/B), executes automatic
scale adjustment based on the trace data when the key is pressed. The trace is
magnified and displayed so that the graph contains the entire data, allowing you
to easily grasp the overall characteristics. You can select the data trace or the
memory trace with the SCALE FOR [ ] key in Table B-28, "Scale reference
(Scale Ref) menu (1-2/2)," on page 373.
SCALE/DIV For the selected trace (data trace/memory trace of trace A/B), sets a value for the
scale per division in the axis for measured value. This is one of the scale
configurations using REFERENCE POSITION, REFERENCE VALUE, and
SCALE/DIV.
REFERENCE POSITION For the selected trace (data trace/memory trace of trace A/B), sets the position of
the scale reference line. The position of the reference line is indicated by a value,
assuming that the lowest line of the graph is 0 and the highest line is 10. This is
one of the scale configurations using REFERENCE POSITION, REFERENCE
VALUE, and SCALE/DIV.
REFERENCE VALUE For the selected trace (data trace/memory trace of trace A/B), sets a reference
value (the value of the scale reference line). This is one of the scale
configurations using REFERENCE POSITION, REFERENCE VALUE, and
SCALE/DIV.
MKR ® REFERENCE
For the selected trace (data trace/memory trace of trace A/B), substitutes the
absolute value of the main marker into the reference value (the value of the scale
reference line) regardless of the value of the D marker. As a result, the marker
moves to the reference line position.
TOP VALUE Sets a value of the top line in the scale graph. This is one of the scale
configurations using TOP VALUE and BOTTOM VALUE.
BOTTOM VALUE Sets a value of the bottom line in the scale graph. This is one of the scale
configurations using TOP VALUE and BOTTOM VALUE.

SCALE FOR [ ] When both the data trace and the memory trace are displayed on the screen,
selects the kind of trace to which the scale configurations in Table B-27, "Scale
reference (Scale Ref) menu (1-1/2)," on page 373 are applied from the data trace
[DATA] or the memory trace [MEMO].
D&M COUPLE ON off When both the data trace and the memory trace are displayed on the screen,
selects performing the scale configurations in Table B-27, "Scale reference
(Scale Ref) menu (1-1/2)," on page 373 for both the data trace and the memory
trace together (couple on) or for each of them separately (couple off).
