OPERATING INSTRUCTIONS
1. In an area where combustible gas is known to be not present,
press the power button
13
for 3 seconds. The tester will beep and
start a 50-second zero-calibration process while the first indicator
light blinks
4
. Once complete, all indicator lights
4
will blink for
one second, then the HIGH
6
indicator light will illuminate and
continue to flash, indicating it is ready to take a measurement.
2. Start measuring in the High sensitivity mode (50 to 1,000 ppm).
To view higher values (1,000 to 10,000 ppm), press the LOW
button
10
to enter Low sensitivity mode.
3. Point the sensor
3
towards the area to test. As all indicator
lights are illuminated in High sensitivity mode, switch to Low
sensitivity mode by pressing the LOW button
10
. NOTE: This may
cause most of the indicator lights to turn off. In Low sensitivity
mode, concentration levels are measured in larger intervals than
in High sensitivity mode, meaning greater concentration levels are
required to illuminate each indicator light.
4. As you get closer to the source of a leak, the concentration levels
detected will increase, as indicated by increasing audible/visual
alarms. Move the sensor head in the direction of increasing
audible/visual alerts to the source of the leak.
WARNING: High concentrations of combustible gasses can
cause explosions, res, asphyxia, and other hazards that
could cause serious personal injury or death. Know the
characteristics of the gas you are working with and use proper
precautions to avoid hazardous conditions.
