Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 4:
5. The luminometer of claim 2, further comprising:
a light emitting diode arranged such that the light detector measures photons emitted from the light emitting diode; and
wherein the luminometer controller is configured to:
determine a minimum readable signal that generates the low voltage value from the light detector when the minimum readable signal is applied to the light emitting diode;
determine a high signal that generates the predetermined value from the light detector when the minimum readable signal plus a buffer voltage is applied to the light emitting diode;
select a first voltage and a second voltage between the high voltage and the minimum readable voltage that divides the minimum readable voltage to the high voltage into four equal increments;
receive a plurality of calibration analog signal values and a plurality of calibration photon counts from the light detector based on applying each of the minimum readable voltage, the high voltage, the first voltage and the second voltage to the light emitting diode; and
perform a linear regression using the plurality of calibration analog signal values and the plurality of calibration photon counts to generate the linear function.
