Figure 20 Channel Detail Screen
a) Select “Channel Description”. The keyboard will appear, allowing the input of the Channel Tag
Name, or a brief description of the sensor, up to 20 characters maximum. The “Channel Description”
here must match the “Channel Description” entered at the Main 880.
b) Select “Gas Type”, and input the gas type of the sensor. (i.e., H2S, LEL, CO2, etc.) Up to 10
characters maximum. The “Gas Type” entered here must match the “Gas Type” entered at the Main
880.
c) The Range of the sensor is transferred by the Main 880 and should not be changed in the Remote
Display. However, the decimal point must be set for the range to be correctly displayed. Therefore
ranges of 10 for a unit of 10ppm or 10% will be displayed as 100, likewise entries of 5 for 5ppm or
5% will be displayed as 500. To correctly place the decimal point in the entry, select the “Decimal
Place” box and enter the decimal point placement. (i.e., a “Range” entry of 100 with a “Decimal
Place” of 1 provides a range of 10.0, 10ppm or 10%. Likewise, a “Range” entry of 500 with a
“Decimal Place” of 2 provides a range of 5.00, 5ppm or 5%.)
7) Proceed through all channels, setting each channel’s “Channel Description” and “Gas Type” to that setup
in the Main 880. When all channels have been correctly set-up the unit should be ready for normal
operation.
5.0 System Operation

screens and accessing data fields is accomplished by touching the wand to the appropriate area, box, button, or
key on the screen. The provided “wand” should be the only instrument used to activate the screen as other
instruments may cause damage to the screen.
5.1 Main Screen
The main screen is the default screen of the unit (Figure 21). The screen displays the first 8 channels, channel
