Difference: The difference between
measured value and correction value
13
Measured value: The difference between the
perfect PCB top surface and the measured
PCB top surface
(If the measured PCB top surface is
higher
than perfect one, it displayed as positive
value)
Correction value: The same coordinate value
of the correction curve calculated from
the measurement result
●If the difference exceeds 0.3 mm, it
results in error, the background in the
frame turns in yellow.
For obtaining the applicable correction
curve, review the measurement
points. Also, if the measured value or
correction value is -4.5 mm or less,
or +2 mm or over,, it results in error.
