2. TYPICAL APPLICATION
2.1 Amplifier
The amplifier for each channel has had its level of amplification (gain) set at the time of manufacture
and is not user changeable.
Different sensors have different scaling / output voltage limits, This is due to the amount of gain that
we are able to apply, and these are evaluated at the time of ordering. Common scaling may be 1 volt = 10
of unit X, yet any desired range may be possible. e.g. 1.23 Volts = 567 unit X, depending on the application.
It is possible to have different channels providing different output ranges for a given sensor, but only
one range would be available at any one time. There is a maximum of four channels so one sensor may
have a maximum of four selectable ranges. For example, two sensors would have a maximum of two different
ranges for each sensor.
e.g.
Channel 1 (e.g. PAR Quantum) 1 volt = 100

Channel 2 (e.g. PAR Quantum) 1 volt = 20,000
