3.2.3 Function setup
• Use this procedure to set up the conditions necessary for measurement.
For each program number register measurement conditions including the segment (part
feature to be measured), measurement interval (measurement time), and GO/NG judgment
criteria that are the best suited for the objective workpiece.
• To enter the function setup mode press the
SET
key in the ready state. Each of the
LIMIT
,
SHIFT
+
MASTER
/
OFFSET
, and
REF
keys allows the individual setup item to be
established, and the
key enters the setup operation for items which are most
frequently accessed for set up.
• For more information refer to Section 4.5, “Setting Up the Functions”.
3.2.4 Setups according to the property of each workpiece
For measuring workpieces that transmit light or have a dimension smaller than the diameter
of the scanning beam it is critical to make setups that take into account the properties of the
workpiece.
3.2.4.1 Transparent object (Workpiece that transmits light)
a) Round bar
• Workpieces such as fiber optics and glass tubes are more or less transparent, while
workpieces made of steel are not. This requires different segment settings.
The segment settings for an opaque object and a transparent object are as follows:
• Setup for measurement of transparent or opaque object is possible in the basic setup.
Segment 2
Segment 4
Segment 1Segment 1
Segment 3 Segment 2
Segment 5 Segment 3
Transparetnt
Workpiece
For transparent mode
Laser scan direction
Photo-electric signal
For opaque mode
Binary voltage (SHL)
b) Plate (Sheet)
• If the workpiece being measured is a transparent plate (sheet) with edges that are not
chamfered or beveled, measurement may be aborted because there is not a sharp
contrast in the amount of light at the transition from the highlighted portion to the
shaded portion.
3.2.5 Latch (holding) of the displayed value
• In a single-run measurement, etc., GO/NG judgment and analog output will be continued
while the measured data is latched (held) on the display for the specified period of time.
After the set period elapses, system operation returns to the ready state.
• Set up the display latch timer in the basic setup.
• While the display is being latched, inputs from the I/O interface or RS-232C/GP-IB are still valid.
