The fluorescence chamber temperature is measured with a thermistor. The
voltage across the thermistor is fed to the main processor for use in
calculating and displaying the reaction chamber temperature. The voltage
across the thermistor is also compared to a set-point voltage and used to
control that the reaction chamber heaters to maintain a constant
temperature.
The common electronics contain the core computational and power
routing hardware for the 43iQHL, and is replicated throughout other iQ
series products (
). It also contains the front panel display, the
USB ports, the Ethernet port, and the optional I/O interfaces (RS-485,
analog, and digital).
shows the PCBA interconnect structure for the 43iQHL,
including options. The modular design of the instrument is conveyed in
the architecture. Brief descriptions of the specific PCBAs follow.
