Updating the Alarm Point Settings
The ALARM--P menu item allows you to update one or more
warning, alarm, STEL, and TWA (for CO) settings (the reading at
which the Gas Tracer recognizes these conditions).
For the combustible gas channel, it is not possible to adjust either the
Warning or Alarm settings to be higher than 60 %LEL. In addition, the
Warning setting cannot be adjusted higher than the Alarm setting for
all channels.
NOTE: It is not necessary to adjust every setting for every channel
when you enter this menu item. All settings are shown here
for example.
