Setting Gain - Omron ZS-HL User Manual

■ Setting Custom Mode
If you cannot perform measurement in the provided measurement modes, use Custom
mode.
You can change additional lines and exposure time, so that a measurement can be per-
formed under conditions suitable for the surface status of the workpiece.
Set in the order of [LINE] → [EXPOSE] → [SKIP].
If you set an additional line, its exposure time is automatically determined. If the light amount is still
insufficient, set the exposure time. When [SKIP] is set to ON in this state, the effective line width is
doubled.

Setting GAIN

You can set the CMOS gain so that even workpieces having an extremely low amount of
reflected light or workpieces having a large tilt can be measured stably.
The measurement resolution sometimes drops when a large gain is set. Also, this function increases the
gain on the light receiving side. Therefore, please note that the Sensor Controller can be easily affected
by ambient light.

Setting
1, 2, 3, 4, 5
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 surface, or to
measure at a single pinpoint on the workpiece (reduce the number of addi-
tional lines).
Range: 1 to 200
(The maximum number of lines changes according to the exposure time setting.)
Usage Width of Line Beam p.8-20
Set this item when exposure is insufficient and the exposure time must be
lengthened to increase the amount of received light.
- For Single mode
Range: 0.2 ms to 20 ms
- For Multi-mode
Range: 0.5 ms to 20 ms
When the internal measurement time is longer than the exposure
time setting, the exposure time (= sampling cycle) sometimes is
greater than the setting.
Check the actual sampling cycle in [SYSTEM]-[INFO]-[CYCLE].
Set this item to extend the measurement line width without changing the mea-
suring time.
The effective line width is doubled when this setting is ON.
Range: ON, OFF
Adjusts the internal gain of the CMOS image sensor. (default value: 1)
