%LEL is chosen as the unit, any ppm or %volume data is converted and

graphed as %LEL. The user may change back and forth between the units

for the graph and still have all data shown. The CAT Range Select box is

where the user may select %LEL, ppm, or %volume as the units for the

graph.

• If installed, an IR HC or CH

channel can be graphed in %LEL or % volume

in order to accurately depict the full range of the sensor.

If the channel is configured as a %LEL only channel, then data will only be

recorded in %LEL and the range will be 0-100% LEL. Any gas

concentration above that level will not be recorded.

If the channel is configured as a %LEL/% volume autoranging channel,

then data will be recorded in %LEL and % volume where appropriate. It will

record data in %LEL up to 100% LEL and then it will start recording data in

% volume up to 100% volume. If %LEL is chosen as the graphing units, all

data collected for a %LEL only channel will be displayed. Any data

collected in an autoranging configuration that exceeds 100% LEL will not

be shown. In order to view data above 100% LEL, % volume must be

selected. When % volume is selected, all data will be shown in terms of %

volume.
