WARNINGS
To ensure safe operation and service of the tester, follow these
instructions. Failure to observe these warnings can result in severe
injury or death. 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.
• Read, understand, and follow all instructions to ensure safe operation.
• Always turn on the gas detector in an area known to be free of combustible
gasses.
• Initial calibration should be performed in an area known to be free of
combustible gasses. Calibration in an area containing combustible gas will
result in incorrect calibration and lower than actual readings. This could
result in combustible gasses not being detected.
• The combustion gas leak detector is NOT intended as a personal protection
device (PPE).
• Do NOT replace batteries in an explosive atmosphere.
• The combustion gas leak detector is NOT insulated. Avoid contact with
areas where energized conductive elements may be present. Shut off
power to the area before starting measurements.
• Do NOT probe moving machinery that could catch any part of the meter
and cause harm to the operator and the meter.
• Always wear approved eye protection.

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 sour
ce 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.
