To exit from an entered-information screen and go back to Measuring Mode, press and
release POWER MODE until you get to the Measuring Mode screen.
NOTE:
Each screen displays for 20 seconds. If you do not press a button within 20 seconds,
the SC-04 automatically returns to Measuring Mode.
Peak Screen (PEAK)
The peak screen displays the highest concentration detected since the SC-04 was turned on.
The peak reading is stored until a higher level is detected, the peak reading is cleared, or the
SC-04 is turned off.
The lunch break feature enables the SC-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 pg.14).
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.
STEL Screen (STEL)
The STEL Screen displays the short term exposure limit (STEL) reading. The STEL reading
is the average reading
over the last 15 minutes
