HC Range Screen
This screen displays only if your GX-2003 is equipped with both the catalytic
% LEL combustible sensor and the TC % volume combustible sensor. It
allows you to select the display units for the combustible channel as
% LEL/% volume autoranging or % volume. If autoranging is
selected, the CH4 reading will be displayed in % LEL up to 100% LEL,
which is equivalent to 5% volume for methane (CH
4
). Above 100%
LEL, it will be displayed in %volume. If % volume is selected, the CH
4
reading will be displayed in % volume only.
CAUTION: If the combustible channel is set for % volume only, then there
are no gas alarms for any detection channel.
To update the HC range setting:
1. After entering Display Mode and arriving at the HC range screen,
press and release the ▲AIR button. The current setting will flash at
the bottom of the LCD.
2. Use the ▲AIR or (SHIFT)▼button to change the setting.
3. Press the POWER ENTER button to save the change and advance
to the next screen.
