The EPOCH 4PLUS automatically collects A
max
, T
1,
and T
2
and calculates a “k factor”
from the known reference height. These three collected values (A
max
, T
1,
and T
2
) are
displayed on the screen in their respective positions using “x” marks. The operator now
has the option of manually entering any of those data points that does not look accurate
([F1], [F2], or [F3]), accepting the calibration ([F4]), or clearing the entire calibration and
starting again ([F5]).
Once you are satisfied with the collected data, press [F4] to accept the calibration and to
begin inspecting.
9.17.4.2 Manual Mode
When the PEAK MEMORY function is not in use on the EPOCH 4PLUS, it is possible to
manually collect each calibration data point to calibrate the instrument for inspection.
This manual collection works only when the PEAK MEMORY function is OFF or after
data has been collected using the Envelope Mode (see above).
