SAFETY TIPS
One year limited warranty
Using this detector, read all safety information carefully.
“WARNING” is used to indicate conditions or actions that may pose physical hazards to the user.
“CAUTION” is used to indicate conditions or actions that may damage this instrument.
WARNING!
Charging or discharging batteries may give off an explosive gas. Keep away
from open flame and sources of ignition from the battery at all times.
INTRODUCTION
The CD100A Combustible Gas Leak Detector is capable of sensing many combustible, non-combustible and toxic gases that include but are not limited to the following:
| Acetone | Industrial Solvents |
|---|---|
| Alcohol | Jet Fuel |
| Ammonia | Lacquer Thinners |
| Benzene | Methane |
| Butane | Naphtha |
| Ethylene Oxide | Natural Gas |
| Gasoline-Petrol | Propane |
| Halon | Refrigerants |
| Hydrogen Sulfide | Toluene |
NOTE: This leak detector is factory calibrated for methane in air.
WARNING! This unit should not be used for detection of Carbon Monoxide.
Features include
- Fully adjustable steady tic rate accelerates as the sensor tip approaches a leak (the adjustment knob is located on the side of the unit)
- “Tip-Light” in sensor cover used to see around the area of leak in a dark environment
- Long 18” flexible gooseneck
- Audible and visual leak indicator
- Low battery indicator and separate battery compartment for easy replacement
- Power On light
- Solid state semiconductor sensor provides instantaneous detection
- Sensor cover to protect sensor
- Ruggedized protective rubber boot
- Socket for optional earphone

FUNCTIONS
- Senses leading combustible, non-combustible, and toxic gases
- Minimum detection: 50 ppm methane
FEATURES
- Long 18” gooseneck for hard to reach areas
- Tip-light in sensor cap illuminates the search area
- Sensor provides accurate detection
- Audio and visual tic rate, fully adjustable
- Headphone jack
- Low battery indication
- Sensor cover
- Protective boot
OPERATING INSTRUCTIONS
- Turn the instrument on by rotating the thumbwheel downward in a non-contaminated environment (fresh air).
- The green power LED will be illuminated when the unit is turned on. If the battery level is low, the red LED will be steady and the tic will not be adjustable. The battery will need replacing.
- Adjust to slow uniform tic rate with the use of the thumbwheel (approximately two tics per second). This sets the instrument to the background level. Start your testing by setting the instrument in fresh air. The red LED indicator will flash in correspondence with the tic rate. Allow about 10 seconds for the sensor to stabilize indicated by a steady tic rate. (It may require up to two minutes to stabilize).
- The unit responds to gas with a variable audible tic sound. The audible tic increases in volume when exposed to gases with 50 parts per million or more. When gas is detected, the tic rate will increase, rotate the thumbwheel back to the steady tic, resettingthe instrument to this new background level. Move the instrument into higher concentrations of gas (indicated by increase tic rate) until the leak is found.
- The “Tip-Light” is used to see around the area of the leak in a dark environment.
- When this instrument is used in noisy environments, look at the red LED, which flashes more rapidly as the tic rate increases. The optional earphone can be plugged into the side of the unit, if there is high background noise or the operator does not want to disturb other people. This also disables the speaker.
- If the tic rate becomes uncontrollable, it may be necessary to change the sensor.
- The detector will respond to some leak finding solution (soap), so use your detector first. If over exposed to some gases, the detector may take an extended period of time to return to normal.

SENSOR FILTER AND SENSOR REPLACEMENT’
The sensor is housed at the tip of the gooseneck assembly, and has a life of more than three years.
To remove the sensor:
- Turn the unit off.
- Pull off the top half of the sensor housing. (Pushing to one side aids removal)
- With care, move the “Tip-Light” LED to one side to gain access to the sensor (small silver can).
- Unplug the sensor and replace it with a new one.
- The sensor can be fitted in either one of two ways without affecting instrument operation.
- Realign the LED, ensuring it sits above the sensor.
- Replace the sensor cover by pushing it firmly in place.
BATTERY REPLACEMENT
- Turn off the power and remove the battery case cover.
- Remove and dispose of old 9V alkaline battery promptly in a manner consistent with disposal regulations. Always use a 9V alkaline battery. Ensure the polarity of the battery matches that shown in the compartment.
- Replace the battery case cover.

ELECTROMAGNETIC COMPATIBILITY
The European Council Directive 89/366/EEC requires that electronic equipment does not generate electromagnetic disturbances that exceed defined levels and has an adequate level of immunity to enable it to be operated as intended. The specific standards applicable to this product are detailed in the appendices.
Since there are many electrical products in use that pre-date this directive and may emit electromagnetic radiation in excess of the standards defined in the directive, it may be appropriate to check the analyzer prior to use. The following procedure should be adopted:
- Go through the normal start sequence in the location where the equipment is to be used.
- Switch on all localized electrical equipment that might cause interference.
- Check that all readings are as expected. (Generally, a low disturbance is acceptable.) If not, adjust the position of the instrument to minimize interference or switch off the offending equipment during the test. There has been no awareness of any field based situation where such interference has ever occurred since the writing of this manual (April 1998). This advice is only given to satisfy the requirements of the directive.
This product has been tested for compliance with the following generic standards, and it is certified to be compliant.
