Following the Set-Up and Operation instructions, turn ON and calibrate the
gas detector. Once calibration is complete use a combustible gas source
(such as an unlit lighter), to confirm that the gas detector senses the gas. If
the gas detector does not sense the gas, do not use the unit until ithas been
properly serviced. Remove the gas source and allow several minutes for the
sensor to stabilize prior to use.
7-Set-Upand Operation
Warning
High concentrations of combustible gases can cause explosions, fires, 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.
Always turn on and calibrate the gas detector in an area known to be free of
combustible gases. Calibration in an area containing combustible gas will result
in incorrect calibration and lower than actual readings. This could result in
combustible gases not being detected.
Set up and Operate the gas detector according to these procedures to reduce
the risk of fire, explosions and serious injury and incorrect measurements.
7-1.0peration
Check for an appropriate work area as indicated in the General Safety Section.
Determine the application and confirm that you have the correct equipment. See
the Specifications section for information on sensitivity, gases detected and
other information.
Make sure that allequipment hasbeen properly inspected.
In an area where combustible gases are known to not be present, turn on the
gas detector by pressing and releasing the ON/OFF button for one second. The
gas detector will vibrate, beep, and the first level red light will illuminate to
indicate that the unit isON. The gas detector then starts an approximately 50
second sensor heat up and calibration, during which the first level red light is
blinking.
Once the calibration is complete, for one second, alllevel lights will flash, and if
the audible and vibration alerts are ON, the unit will beep and vibrate. Then
either the high (yellow) or low (white) light will be ON. Ifthe high (yellow) and low
(white) sensitivity lights are ON at the same time, this indicates that the batteries
need to be charged. Ifalldisplay lights are ON, this indicates that the sensor has
failed and that the unit needs to be serviced.
