Abstract
Abstract @ A portable analyzer (10) is disclosed. The analyzer comprises in combination a housing (12), an optical system comprising a light source (10), a detector (16), and one or more means (18) for activating the optical system in generating a signal in response to a test element, means (45) for manually moving the test element (33) from a first position to a second position corresponding to a point of initiation of an operative condition of the optical system, means (46) biasing the moving means toward said first position for controlling movement of the test element from the second position to the first position, means (22, 24, 26) cooperative with said optical system, for processing the signal, and means (54). cooperative with the means for processing the signal, for displaying the processed signal.

Claim 1
Independent Claim
126 words
An analyzer (10) comprising in combination - a housing (12); an optical system comprising a light source (14), a detector (16), and one or more means (18) for activating said optical system and generating a signal in response to a test element (33a,b); means (45) for manually moving the test element from a first position to a second position corresponding to a point of initiation of an operative condition of said optical system; means (46) biasing said moving means (45) toward said first position for controlling movement of the test element from said second position to said first position; means (22,24,26), cooperative with said optical system, for processing said signal; and means (54), cooperative with said means for processing said signal, for displaying the processed signal.
Claim 2
Dependent Claim
126 words
An analyzer (10) comprising in combination - a housing (12); an optical system comprising a light source (14), a detector (16), and one or more means (18) for activating said optical system and generating a signal in response to a test element (33a,b); means (45) for manually moving the test element from a first position to a second position corresponding to a point of initiation of an operative condition of said optical system; means (46) biasing said moving means (45) toward said first position for controlling movement of the test element from said second position to said first position; means (22,24,26), cooperative with said optical system, for processing said signal; and means (54), cooperative with said means for processing said signal, for displaying the processed signal.
Claim 3
Dependent Claim
