UltraRAE 3000 User’s Guide
During the Span calibration process, there is a 30-second countdown
and the instrument performs the Span calibration automatically. It
requires no actions on your part.
Note:
If you want to abort the Span calibration process, press [N/-] at
any time during the process. You will see a confirmation message that
says “Span is aborted!” and then the Zero calibration menu appears.
You can then proceed to perform a Zero calibration, perform a Span
calibration, or exit to the topmost Calibration menu.
When Span calibration is complete, you see a message similar to this
(the value is an example only):
Span 1 is done!
Reading = 100.0 ppm
The instrument then exits Span calibration and shows the Zero
calibration menu on its display.
Note:
The reading should be very close to the span gas value.
