The LT-9001 Series has two types of gains to receive
the light intensity. You can choose one from the
following two options.
• STANDARD : Measures the target
with the standard
gain.
• HI GAIN (High sensitivity) : Measures the target
with higher gain.
It is recommended to measure the target with the
[STANDARD] gain if there is no problem with the
measurement. With [HI GAIN], the gain of the noise
element is also increased and that may cause the
unstable measurement.

become unstable.
