Register Number Select the number of the integer, double-length integer, or real num-
ber register to be traced. Any register number set in the Trace Data
Definition field under the Data Trace Definition Tab Page can be
selected. Register numbers cannot be selected, however, while in the
automatic update mode.
Scale Conversion
Value Input the scale conversion value for the trace data. Changing this
value adjusts the vertical amplitude of the graph. With automatic
updating, this value is continually displayed as the amplitude. (Refer
to Updating Display Data under 4.5.5 List Tab Page.) The default
setting is the value set for "SCALE" in the Trace Data Definition
field under the Data Trace Definition Tab Page. If 0 is set, the ampli-
tude will be the same as if 32767 is set.
