You have two options:
• Press [-] to exit without making a change.
• Press [+] to go back to change the value.
Meas. Gas (Advanced Mode)
PIDs can be calibrated to a reference gas, yet display the
concentration readings in equivalent units of the target gas.
Isobutylene is typically used as the calibration gas because it is
inexpensive, readily available, has immediate sensitivity, and has very
low toxicity. The RAEGuard PID can display concentrations of over
200 gases using the built-in library of correction factors. Refer to
RAE Systems Technical Note TN-106, available online at
www.raesystems.com, for further details.
Measurement gases are organized in two lists:
• Last Ten is a list of the last ten gases used by your instrument.
The list is built automatically and is only updated if the gas
selected from the Gas Library is not already in the Last Ten. This
ensures that there is no repetition.
• Gas Library is a library that consists of all the gases found in
RAE Systems’ Technical Note TN-106 (available online at
www.raesystems.com).
•
Press [-] to step between the two options.
•
Press [MODE] to go back to the menu level above it.
•
Press [+] to select your choice and advance to its submenu.
