INSTRUCTIONS
1. Move the eL-320 to a fresh-air environment. Press the
button to turn the unit on.
2. The LED will flash rapidly for a period of time (see WARM-
UP TIME, below) to indicate warm-up and auto-calibration,
afterwards the unit will begin beeping and flashing green.
3. Unit turns on in the high sensitivity level, which is preferred
for most small leaks. To operate the unit in the low
sensitivity level, press the button twice (double-click like a
computer mouse). The LED will fade from green to red and
a sweeping sound effect of high to low pitch will be heard.
This low sensitivity mode is useful for pinpointing very large
gas leaks.
4. Double click again to change back to high sensitivity.
5. Move the probe towards a suspected gas leak at a rate of
less than 1 inches (25 mm) per second, no more than ¼
inch (5 mm) away from the suspected source.
6. If a leak exists, the sound will increase in rate and pitch and
the LED will start flashing rapidly.
7. Alarms caused by very large leaks may take a long time to
clear. If this is the case, switch to the low sensitivity mode
as detailed in (3) above.
8. To turn the eL-320 off, press and hold the button for 3
seconds.
