4.8.2 Change LEL/VOC Gas Selection
This function allows a choice of one of the pre-stored LEL or
VOC gases in the monitor and calculate its correction factor
relative to the LEL or VOC calibration gas. This factor will then
be used during gas measurements to show the equivalent
concentration of the selected LEL or VOC gas. The user can
also modify this relative correction factor to increase or
decrease the gas reading. This allows the user to create a
custom factor for a specific gas or mixture of gases.
1. “Change LEL/VOC Gas Selection?” is the first submenu
item. Press [Y/+]. If an LEL sensor is installed, the display
shows:
TOX1
VOC
TOX2
LEL Gas = ?

Otherwise, the message “No LEL installed” is displayed,
and skip to Step 8.
2. If you do not want to change the LEL measurement gas,
press [Y/+] to accept the current gas and skip to Step 6.
3. If you want to modify the LEL measurement gas, press
[N/-] first, then use [Y/+] or [N/-] to scroll through a list of
gas names until the desired gas name appears in the LCD
display, then press [MODE] to select the new gas name.
4. The display shows “Save new gas?” To confirm the new
gas, press [Y/+] to accept the change. Press the [N/-] or
[MODE] to discard the change and move to the next step.
