On or OFF. This alarm is parcularly useful in noisy surroundings
where the audible alarm might be dicult to hear. Vibraon frequency
increases as gas concentraons increase.
3. “PPM SPEEDOMETER” (ON THE DISPLAY)
At the top of the LCD display, there is an innovave analog “speedome-
ter type” display. If no gas is detected, only a “0” will appear at the
top LEFT of the speedometer. But, if gas is detected, the speedometer
will “sweep” to the right to reect the PPM level being detected. This
speedometer scale helps technicians (in their peripheral vision) to mo-
nitor the “rate of gas concentraon change” as they move closer to, or
further away from the source of a leak.
4. “PPM” NUMERICAL DATA ON THE DISPLAY
When the LSCG detects a combusble gas (having a Methane com-
ponent), it generates numerical “PPM” (“Parts Per Million”) values
of Methane on the LCD display. A key benet of this innovave digital
display is that it gives HVAC/R technicians specic, real me, combus-
ble gas concentraon values. Therefore, technicians don’t need to
remember what mulple LEDS represent as is commonly required
on compeve analog leak detectors.
5. “LEL %” NUMERICAL DATA ON THE DISPLAY
For any gas (with a Methane component) detected, the LSCG
will also show an “LEL” or “Lower Explosion Limit” value as a
percent volume. This reading lets technicians know if the gas
being detected is close to, or well away from the point at which
it might combust. More detailed information on LEL can be
found on pages 13-14.
