4.8.2 Change LEL/VOC Gas Selection
This function allows the user to choose 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
Gamma
LEL Gas =?
Methane
LEL
OXY
Otherwise, the message “No LEL installed” will be
displayed and skip to Step 8.
2. If the user does not want to change the LEL measurement
gas, press [Y/+] to accept the current gas and skip to Step
6.
3. If the user wants 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.
