Transfer Correction
Transfer Correction is an adjustment in the reference gain setting during calibration of
the instrument, and is typically added when the surface conditions between a
calibration block and test piece are different. The coupling conditions on the test
surface can often cause signal loss after calibrating a DAC curve, which results in
inaccurate comparisons of the test reflectors with the calibrated DAC curve. The
EPOCH 650 can be easily adjusted for this potential difference by adding transfer
correction to the calibrated base gain after completing the DAC curve setup.
To add transfer correction to a completed DAC curve
1.
Choose
Basic
.
2.
Press dB.
3.
Use the Up and Down arrow keys or the adjustment knob to bring the scanning
gain to the desired level for transfer correction.
4.
Press
Add
(P2 key) to add the scanning gain to the base gain and to apply the
transfer correction.
