    Electrical Warnings: The BC 1060 is a 12 Volt DC powered system, and there are no hazardous live voltages located anywhere inside the instrument. It is equipped with an external desktop power supply module with a 100-240 VAC 50/60 Hz input range, and a 12 VDC, 8.5 A output. The BC 1060 instrument is housed in a weather-proof case for deployment outdoors.

  • Page 8: Site Selection And Positioning Criteria

    2 SITE SELECTION AND POSITIONING CRITERIA There are no special installation requirements for the BC 1060. It should simply be positioned in the area containing the air to be sampled based on local monitoring needs. 3 SETUP & DEPLOYMENT The BC 1060 is designed for easy setup and simple configuration for most applications. This section describes the basic assembly, setup, and start-up of the instrument.

  • Page 13: Filter Tape Installation, Loading, And Filter Material Notes

    The BC 1060 carbon monitor uses treated glass fiber filter tape rolls, available from Met One Instruments under part number 460211. It is essential that this tape be used in the BC 1060 in order to maintain proper instrument calibration and reproducibility. Since the filter tape advance frequency depends upon filter-loading, the frequency with which the tape needs to be replaced is variable.
