Setting the Sensing Conditions

Setting the Sensing Conditions
Set the conditions to be used for detecting workpieces by the sensor.

Setting the Measurement Mode

Set the measurement mode.
Select the measurement mode based on the items (e.g. speed, precision, or sensitivity)
that you want to give priority to in measurement.

• In the HI-SPEED mode, the measurement cycle changes according the actual settings. (When only
the average count is set, the measurement cycle becomes the maximum speed (approx. 110 µs.)
Check the actual measurement cycle at [INFO]-[CYCLE] under the top menu.
• Set in order [EXPOSE]→[LINE]→[SKIP].When the exposure time is changed, the maximum possible
number of lines for that exposure time is automatically set.After this, change the LINE setting as
desired. When SKIP is set to ON in this state, the effective line width is doubled.

User's Manual
Setting
This is the standard measurement mode. (measurement cycle: approx. 500
µs) (default)
Select this mode to measure workpieces with sensitivity set high. (measure-
ment cycle: approx. 2 ms)
Select this mode to measure workpieces at high speed. (measurement
cycle: max. speed approx. 110 µs)
Select this mode to measure workpieces with sensitivity set high. In this
measurement mode, sensitivity to received light is much better than the
HIGH PRECISION mode as the sampling time is longer. (measurement
cycle: approx. 4 ms)
Set this item when exposure is insufficient and the exposure time must be
lengthened to increase the amount of received light.
Range: 0.2 ms to 20 ms
Set this item to extend the measurement line width without changing the
measuring time.
The effective line width is doubled when this setting is ON.
Range: ON, OFF
Set this item to make it mode difficult (increase the number of additional
lines) for measurement to be influenced by the state of the workpiece sur-
face, or to measure at a single pinpoint on the workpiece (reduce the num-
ber of additional lines).
Range: 1 to 200
(The maximum number of lines changes according to the exposure time setting.)
Description
When the internal measurement time is longer than the exposure
time setting, the exposure time (= measurement cycle) sometimes
is greater than the setting. Check the actual measurement cycle at
[SYSTEM]-[INFO]-[CYCLE].
