6. If you do not want to modify the LEL correction factor,
press [Y/+] and go to Step 8. To modify this factor, press
[N/-] first. Then starting from the left-most digit, use the
[Y/+] or [N/-] to change the digit value and press [MODE]
momentarily to advance to the next digit. The flashing digit
will move on to next digit to its right. Repeat this process
until all 4 digits of the new factor are entered. Press and
hold [MODE] for 1 second to exit data entry mode. If there
is any change to the existing value, the display shows
“Save?” Press [Y/+] to accept the new value and exit the
gas selection submenu. Press the [N/-] to discard the
changes.
7. If the VOC sensor is installed, the display shows:

Otherwise, the message “No VOC installed” is displayed
and moves to the next submenu.
8. If you do not want to change the VOC measurement gas,
press [Y/+] to accept the current gas and go to Step 12.
9. If you want to modify the VOC 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.
10. The display shows “Save?” To confirm the new gas, press
[Y/+] to accept the change. Press [N/-] or [MODE] to
