3. DISPLAYS AND KEY OPERATIONS
3.2.8 Automatic measurement with an edge specification
• If the edge specification is made, it is possible to automatically measure IC or connector
leads with respect to their pitch (even intervals), outside diameter, or gap. This is suitable
for inspecting the IC lead bend, etc.
Pitch
Laser
scanning
direction
Gap
Outside
diameter
• This function is only in effect if the necessary setups are made for edge specification in
the basic setup.
• In the function setup designate whether automatic measurement should be performed (for
pitch/outside diameter/gap measurement) or not (manual measurement). Also designate
both the start and finish edges.
• This is available in combination with automatic workpiece detection.
• If automatic measurement has also been selected, the following will take place.
a) In the ready state the first objective portion of the workpiece to be measured will be
displayed.
b) Automatic measurement will be involved in a single-run measurement or continuous-
run measurement.
If “Err-0” (insufficient number of edges to be measured) is detected, the measuring
operation is stopped for the single-run measurement, and the collected measured data is
cleared for continuous measurement to wait for a proper workpiece to be loaded.
c) If the measured data is found to be ±NG, the first source of the ±NG will be displayed
and the measuring operation is stopped. If GO results, the mean of all measurements is
displayed.
d) If the measured data falls within the range of GO, the elapsed measurement time was as
follows:
(Number of measurement edges) x (measurement interval) + (calculation time: 20 ms)
e) The W.P. LED shows the current portion of the workpiece being measured.
