3-1-2 [A1] Sampling period

Sets the time needed to perform one measurement (sampling time).
The CD2H uses automatic sensitivity compensation to ensure the optimal received light amount within a set
sampling period.
When using a high-speed setting (such as 133.3 μs), the response time becomes very fast, but the received
light amount is reduced. This may prevent measurement from being possible at long distances, for black
targets with minimal reflection, or for tilted targets. In such situations, set a longer sampling period or change
the setting to Auto.
The response time will be slower when set to a longer sampling period, but this will allow more time for
capturing light. Note that setting the sampling period longer than necessary will result in high saturation.
When set to Auto, the sampling period is always changed to the optimum value so that measurements can
be performed with the optimum received light amount.
Use the received light waveform mode to check the received light amount.
• Setting value: 133.3 μs / 150 μs / 200 μs / 300 μs / 500 μs / 1 ms / 2 ms / 5 ms / AUTO
• Auto: The sampling period is automatically adjusted to ensure the fastest sampling time according to the
received light amount from the target.
• Default value: 200 μs
