Setting the Measurement Sensitivity (Gain Switching)

This section describes how to set the measurement gain according to the surface condition of
the sensing object.
Setting the measurement gain to AUTO will automatically adjust the sensitivity to the optimum
level for the object.
If the amount of reflective sensor light on the object does not change excessively, stable
measurements can be carried out by fixing the measurement gain to an appropriate one.
Five measurement gains are available: [AUTO] for automatic adjustment, and [BLACK],
[WHITE], [METAL] and [MIROR], which are fixed measurement gains. In the case of fixed
measurement gains, the measurement sensitivity increases in the order [MIROR], [METAL],
[WHITE], [BLACK], [MIROR] with the lowest measurement sensitivity and [BLACK] with the
highest measurement sensitivity.
For [AUTO] measurement gain
When the received light
amount is not sufficient
For fixed measurement gains (other than [AUTO])
When the received light
amount is not sufficient
AUTO can be set only when the Sensor Head is the Reflective type and the intensity mode is disabled.
