Note: The target photodiode DC level will depend on the application and site
characteristics. For example, dust levels and amount of beam
divergence for long path length applications.
The maximum DC gain level will depend on the gas measurement and
pathlength. These limits are set as part of the measurement
parameters.
Too high photodiode DC level will cause an XXXX error status and
incorrect readings
