Chapter 4: Display Mode
OX-04 Operator’s Manual
Peak Screen (PEAK)
The peak screen displays the lowest concentration detected since the OX-04 was turned on. The
peak reading is stored until a lower level is detected, the peak reading is cleared, or the OX-04 is
turned off.
The lunch break feature enables the OX-04 to save the peak reading when it is turned off so it can
continue with the same peak when it is turned on again (see page 16).
To clear the peak reading, do the following:
NOTE:
If
Password Protection
is set to
On
using the 04 Series Setup Program, the peak
reading cannot be cleared.
1. After entering Display Mode, press and release POWER MODE until
PEAK
appears.
2. Press and hold AIR until the screen prompts you to release it.
3. The peak reading is reset and the unit returns to the Peak Screen.
If you do not want to clear the peak reading, release AIR before the above screen sequence
occurs. The unit returns to the Peak Screen.
Changing the User ID (USER ID)
This screen only appears if
DISP.SET
in User Mode is set to
ON
(factory setting) and if
ID DISP
in Maintenance Mode is set to
ON
(factory setting is
OFF
).
Use this screen to select a user ID from the 128 user IDs that are stored in the OX-04’s memory.
Before a user ID is selected on a brand new instrument, the user ID is “----------”. The factory-
installed user IDs have a “U_ID_XXX” format.
The user ID provides a way to identify the OX-04 user during a data logging session.
