UltraRAE 3000 User’s Guide
At the Span Calibration menu, you perform a Span calibration. You
may also go back to the Zero calibration menu or to the initial
Calibration menu if you want to exit calibration.
•
Press [Y/+] to enter Span calibration.
•
Press [N/-] to skip Span calibration and return to Zero
calibration.
•
Press [MODE] to exit Span calibration and return to the top
calibration menu.
If you have pressed [Y/+] to enter Span calibration, then you will see
the name of your Span gas (the default is isobutylene) and the span
value in parts per million (ppm).
IMPORTANT!
If you are using the UltraRAE 3000 to test for benzene, it is
recommended that you calibrate with 5 ppm benzene calibration gas
from RAE Systems.
You will also see this message that prompts you:
1. Turn on your span calibration gas.
2. Press [Y/+] to initiate calibration.
Note:
You may press [MODE] if you decide that you do not
want to initiate calibration. This will abort the span
calibration and take you directly to the Calibration menu for
Zero calibration.
3. Span calibration starts and displays this message:
