micro CD-100 Combustible Gas Detector
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 it has been properly
serviced. Remove the gas source and allow several minutes
for the sensor to stabilize prior to use.
Figure 6 – Warning Labels
Set-Up and Operation
High concentrations of combustible gases can cause explo-
sions, fires, asphyxia and other hazards that could cause se-
rious 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 com-
bustible gases not being detected.

WARNING
Set up and Operate the gas detector according to these proce-
dures to reduce the risk of fire, explosions and serious injury
and incorrect measurements.
1. Check for an appropriate work area as indicated in the General
Safety Section .
2. Determine the application and confirm that you have the cor-
rect equipment. See the Specifications section for information
on sensitivity, gases detected and other information.
3. Make sure that all equipment has been properly inspected.
4. In an area where combustible gases are known to not be pres-
ent, 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 come on to indicate that
the unit is ON. 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, all level 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. If the high (yellow) and low (white) sen-
sitivity lights are ON at the same time, this indicates that the
batteries need to be replaced. If all display lights are ON, this
indicates that the sensor has failed and that the unit needs to
be serviced.
If the gas detector is left ON for more than five minutes with no
activity, it will automatically shut OFF to conserve the batter-
ies.
5. The Audible Alert and Vibration Alert retain the previous state
the detector was last in and can be turned ON or OFF if de-
sired. Press and release the Audible Alert button to turn it ON
and OFF. The gas detector will beep once when the Audible
Alert is turned ON and OFF. Press and release the Vibration
