%volume units depending on the instrument setting. However, when
viewing alarm trend data, the data for the catalytic LEL channel can only be
viewed in one set of units. Use the CAT Range Select box to select the
desired units. If %LEL is chosen as a unit, any ppm or %volume data is
converted and shown in the table as %LEL. The user may change back
and forth between the units for the table and still have all data shown.
• If installed, an infrared methane or hydrocarbon channel records data in
%LEL and/or % volume units depending on whether the channel is
configured as a % LEL channel or a %LEL/% volume autoranging channel.
When viewing the alarm trend data in table format, the units are displayed
as the unit the reading was recorded in. In the following figure, the first
channel is a catalytic LEL channel and the fifth channel is an IR
