twice when turning the Vibration Alert ON and vibrate once
when turning the Vibration Alert OFF.
6. Enter the area to be monitored. Pay close attention to the gas
level indicators (see Table 1). As gas levels increase, more red
level lights will come on and the frequency of the Audible Alert
beeping and the Vibration Alert vibration will increase. See
Table 1 for information on methane concentration levels and
gas detector feedback.

* Gas Concentration levels may differ depending on the specific gas detected
When the gas detector is turned ON it is in whatever sensitiv-
ity state it was last in. In the low sensitivity setting, the lowest
concentration of methane detected is 400 ppm. Switch the sen-
sitivity to the high setting by pressing the high sensitivity button
(H). This will be indicated by the yellow light in the bottom right
of the display. In the high sensitivity setting, the gas detector is
ten times more sensitive, with the lowest concentration of
methane detected at 40 ppm. Sensitivity can be changed at
any time by pressing the High Sensitivity (H) or Low Sensitiv-
ity (L) buttons.
If locating a leak, use the gas detector to find areas of lower

system, trace the system, stopping at the joints to monitor the
gas levels.

by pressing the ON/OFF button.
Maintenance
Cleaning
Do not immerse the micro CD-100 in water. Wipe off dirt with a
damp soft cloth. Do not use aggressive cleaning agents or solu-
tions. Treat the instrument as you would a telescope or camera.

Sensor Calibration/Replacement

The micro CD-100 requires no calibration other than that done at
regular start up. If the sensor should fail, the sensor (Catalog Part
#31948) can be replaced by a RIDGID Independent Authorized
Service Center.

Storage

The RIDGID micro CD-100 Combustible Gas Detector must be
stored in a dry secure area between -10°C (14°F) and 60°C
(158°F).
Store the tool in a locked area out of the reach of children and peo-
ple unfamiliar with the micro CD-100.
Remove the batteries before any long period of storage or shipping
to avoid battery leakage.
