Assignee: BECKMAN COULTER, INC.
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 3:
4. 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;
a light sensor configured to sense light output of the light emitting diode and to generate an LED analog output signal value representing photons emitted from the light emitting diode; and
wherein the luminometer controller is configured to:
apply a minimum readable voltage to the light emitting diode;
increase the minimum readable voltage by a buffer voltage until the LED analog output signal value representing the photons emitted from the light emitting diode when the minimum readable voltage plus the buffer voltage is applied to the light emitting diode is greater than the low voltage value plus a buffer voltage value, wherein the buffer voltage value represents the photons emitted from the light emitting diode when the buffer voltage is applied to the light emitting diode; and
save the LED analog output signal value as the predetermined value.
