Changing the Response, tweaking and testing the results. Response tweaking works by the
user seeing how long it takes to rise from 0 to the expected power and if there is overshoot or
undershoot. See steps
, and
Accepting the results. The graph is drawn with two dotted lines; one at 100% of the expected
measurement at one at 90%. 100% is drawn at about 75% of the full height of the graph to
allow the user to see the overshoot, if there is any.
The following procedure guides you through the specific steps.
To set calibration per Response factor:

. Scaling begins. The graph is scaled to the power level
expected when the reading stabilizes. At this point, the measurement parameters cannot be
changed anymore. Response tweaking works by the user seeing how long it takes to rise from
0 to the expected power and if there is overshoot or undershoot.
The screen displays Scaling in progress.
