1. A method of priming a fluid line comprising:
installing the fluid line in a receptacle of a fluid line state detector;
emitting light from at least one LED of the fluid line state detector a first plurality of times;
monitoring an output signal of a light sensor of the fluid line state detector and determining a maximum light intensity value based on the output signal during the first plurality of times;
determining a primed line threshold based on the maximum light intensity value;
pumping fluid through the fluid line;
emitting light from the at least one LED of the fluid line state detector a second plurality of times; and
determining that the fluid line is primed when the output signal of the light sensor indicates that the light intensity from the LED is in breach of the primed tube threshold.
