Installation manual CF8-D/W-IN General The CF8-D/W-IN is used to measure the carbon dioxide concentration inside incubators.
Figure 1. Terminals and jumpers on CF8-D/W-IN. The darker positions are default settings. The push button is for forcing a manual zero point calibration if the sensor does not enter the automatic zero calibration mode just by flowing zero gas.
Electrical connections The power supply has to be connected to G+ and G0. G0 is considered as system ground. The same ground reference has to be used for the CF8-D/W-IN unit and for any connected device! Unless different transformers are used, special precautions need to be taken.
