UltraRAE 3000 User’s Guide
After the instrument is turned on, it runs through the start-up menu. If
the UltraRAE 3000 is set for “Power On Zero,” then the message
“
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 51 for a more detailed
description of zero calibration.
Start zero calibration by pressing Start [Y/+]. 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, Calibration
Gas & Measurement Gas & Correction Factor, 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.
