ii. "X100" (High Concentration Scale (100 To 10,000 PPM))-To
change to this scale, press the YELLOW "H/L Key". Any
value shown should be multiplied by 100.
6. TEST THE LSCG
a. In an area known free of combustible gas, test the LSCG to
confirm it is working properly.
i. Use a combustible gas (such as an unlit lighter), to confirm
the LSCG detects gas.
ii. If combustible gas is not detected with this simple test, do
NOT proceed with testing for combustible gas on the jobsite.
iii. If a defective LSCG is still under warranty, return it to the
place of purchase for replacement or refund.
7. SEARCH FOR GAS LEAK(S) ON THE JOBSITE
a. In a piping system, slowly trace the system with the end of the
LSCG. Stop at pipe joints (where leaks typically occur) to monitor
gas levels.
b. If using the default X10 Concentration setting, the LSCG will
alarm at 10PPM (or 100 PPM if using the X100 setting).
8. CLOSELY MONITOR DISPLAY READINGS OR ALARMS
a. As gas concentration levels change, so will:
i. PPM Display (Always ON)- 1,000 PPM (when using the LOW
Concentration Setting) Or 10,000 PPM (HIGH concentration
Setting) is the maximum concentration that can be displayed for
any gas the LSCG will detect.
ii. LEL Display (Always ON)- 20 % is the maximum concentration
the LSCG will display.
iii. Audible Alarm Frequency- When ON this alarm increases
in step with gas concentration.
iv. Vibration Alarm Frequency- When ON this alarm increases
in step with gas concentration.
9. WHEN GAS LEAK DETECTION IS COMPLETE
a. Press the ON/OFF key to turn LSCG OFF and store it in the
protective case provided.
1. LOWER EXPLOSIVE LIMIT (Defined)
The MINIMUM concentration of a combustible gas needed to support
