FIELD: measuring equipment.
SUBSTANCE: hand-held test meter for use with an electrochemical-based analytical test strip in the determination of an analyte in a bodily fluid sample, including housing (110), micro-controller (112) disposed in the housing, operating range test strip simulation circuit block ("ORTSSCB", 114) disposed in the housing and strip port connector ("SPC", 106) configured to operationally receive an electrochemical-based analytical test strip. ORTSSCB is in electrical communication with the SPC. In addition, the ORTSSCB is configured to simulate an electrochemical-based analytical test strip inserted into the SPC and an operating range of bodily fluid samples applied to the electrochemical-based analytical test strip by sequentially presenting a plurality of electrical loads. Each of the plurality of electrical loads is configured as a first resistor in series with a parallel configuration of a second resistor and a first capacitor. Moreover, the SPC is configured in electrical communication with the micro-controller. Such hand-held test meters are beneficial in that the operating range test strip simulation circuit block can be employed to easily and repeatedly test operation of the hand-held test meter without the need for an actual electrochemical-based analytical test strip, as well as a plurality of control solutions that mimic bodily fluid samples across the entire operating range of the hand-held test meter.
EFFECT: hand-held test meter with an operating range test strip simulation circuit block is proposed.
