Figure 10.9 AsCal (Graph Mode)
After calibration method/calibration modeconfiguration, you will enter the AsCal running page (assuming you have
selected manual calibration).
You can switch to the graph viewing modeor data viewingmode by
pressing Data/Graph(as shown in Figure 10.9 and Figure 10.10).
In the graph mode, you can see a visual reading of the trend of errors. In
the data mode, you can see the detail data and errors.
On the top of the error graph chart, you can see the maximum tolerance
and set point values.
On the bottom of the error graph chart, is the input and output
information.
You can save the point data and continue to the next point until all points
are accepted by pressing Enter or Accept.
You can skip the current point (do not save the point data) and continue
to the next point by pressing Skip.
When all the set points are done, the AsCal calibration results will appear
automatically.
The calibrator calculates the maximum error, maximum hysteresis, zero
error and span error. Depending on the value of the maximum error, you
can decide whetherto adjust the UUT.
If you just make a calibration test, you can press Esc or Rejectto abort the
