Scale tab setting Description
X-Axis and Y-Axis
Scale
Set the reading value scale for each division for the function
selected.
The choices you see for this setting are directly related to what you
have chosen to plot on the X or Y-axis (on the Data tab). For
example, if you have chosen to plot Time on the X-axis, your
selections on for the X-axis on the Scale tab will be seconds.
For example, if you are sourcing current, you can specify that the
value of the divisions on one of the axes on the graph are set to 1
A intervals.
X-Axis and Y-Axis
Min Position
You can set the first visible value on the graph; the default setting
is 0. The choices you see for this setting are di
rectly related to what
you have chosen to plot on the X or Y-axis (on the Data tab). For

selections on for the X-axis on the Scale tab will be seconds.

readings are being made, Auto Scale is turned off.
Y-Axis Auto Scale
You can turn the Auto Scale function on or off for the Y-axis.
