16 Basic Operation
The instrument is programmed to give you the most commonly needed
information quickly.
Pressing [N/-] steps you from one screen to the next, and eventually return to
the main display. If you do not press a key within 60 seconds after entering a
display, the instrument reverts to its main display.
Note: While viewing any of these screens, you can shut off your instrument by
pressing [MODE].
After the instrument is turned on, it runs through the start-up menu.
Then the message “Please apply zero gas…” is displayed.
At this point, you can perform a zero air (fresh air) calibration. If the
ambient air is clean, you can use that. Otherwise, use a cylinder of
zero air. Refer to Zero Calibration on page 32 for a more detailed
description of zero calibration.
Start zero calibration by pressing Start. You see the message
“Zeroing…” followed by a 30-second countdown.
Note: You can press [MODE] to quit, bypassing the zero air
calibration.
When zero calibration is complete, you see the message:
Zeroing is done!
Reading = 0.0 ppm
The instrument is now sampling and collecting data.
Note: At the Average & Peak, Date & Time & Temperature, and PC
Communications screens, the instrument automatically goes to the main
display after 60 seconds if you do not push a key to make a selection.
