(1) One side of transformer secondary is connected to signal common. Dedicated transformer is recommended. No mains circuit connection allowed. In addition, it is required to use an isolated power supply that is certified by a national or international standard (i.e. UL). Use of a Class 2 LPS power supply or greater is required.
(2) Carbon Monoxide full scale is 1000ppm.
(3) Nitrogen Dioxide full scale is 30ppm
(4) Accuracy of CO2 reading may be reduced at temperatures below 14ºF (-10oC).
