Updating the Alarm Point Settings
This menu item allows you to update one or more alarm points (the
reading at which the GX-2003 recognizes the alarm condition).
1. From the main menu, place the cursor next to the ALARM
POINTS menu item. Press and release the POWER ENTER
button. All detection channels are displayed.
2. Move the cursor next to the channel of the alarm point you want to
update. Press and release the POWER ENTER button. The
channel’s set alarm screen displays for low alarm (in this example
for the combustible gas channel).
NOTE: The GX-2003 displays the set alarm screens for each channel
in the following sequence: low alarm, high alarm, STEL alarm
(toxics only), and TWA alarm (toxics only).
If this is the alarm you want to update, continue with step 3. If not,
continue pressing the POWER ENTER button until the correct set
alarm screen displays, then continue with step 3.
3. Use the ▲ AIR and (SHIFT) ▼ buttons to set the alarm point to the
desired setting. Keep the following in mind:
• The low alarm cannot be set higher than the high alarm and the
high alarm cannot be set lower than the low alarm.
• Any alarm setting can be turned off by adjusting it to its lowest
setting. The setting will be displayed as OFF. To turn off a high
alarm, the low alarm must also be turned off.
• The oxygen low alarm is a decreasing alarm. All all other gas
alarms are increasing alarms.
NOTE: If you want to exit this screen without saving any change to
the alarm point, press the DISPLAY (ADJ) button.
