Up to three pitches can be excluded from measurement, based on the application,
as shown below.
If pitch (1) and pitch (13) are included in the measurement of connector lead
pitches as shown on the right, the maximum value becomes larger than the actual
value. The masking function is useful to cancel these unnecessary part in such a
case.
■ Setting Procedure
1. Select the OPTIONS screen. Press the [OPTIONS] button.
2. Set the masking function.
Press the button corresponding to the output for which the masking function is
to be set.
3. Press the [MASKING] button.
Enter the pitch number to be canceled using the numeric keys, and press
[ENTER]. Press [ESCAPE] to complete the entry. Press [CANCEL] to cancel
the entry. The value returns to the previous value.
Note 1: Pitch number is counted from Pitch 1 in the scanning direction (from the top of the scanning
head to the bottom).
Note 2: When the total number of pitches changes (i.e. due to lead breakage), the control I/O board’s
HI3 output is turned ON which indicates an "Error with No. of Pitches”. (Except for the self-timing mode)
