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

Claim 2:
3. The luminometer of claim 2, further comprising:
a light emitting diode arranged such that the light detector measures photons emitted by the light emitting diode; and
wherein the luminometer controller is configured to:
apply a minimal voltage to the light emitting diode;
increase the minimal voltage to a minimum readable voltage, the minimum readable voltage being a minimum voltage applied to the light emitting diode to cause the light emitting diode to emit sufficient photons for the light detector to measure;
receive an LED photon count and an LED analog signal value each representing the photons emitted from the light emitting diode when the minimum readable voltage is applied to the light emitting diode; and
save the LED analog signal value as the low voltage value.
