Triplett GSM100 Combustible Gas Detector User Manual

Introduction

Thank you for selecting the Triplett GSM100 Combustible Gas Detector. The GSM100 Combustible Gas Detector is a gas leak locating tool that is used to identify the presence of and isolate the source location of combustible gases such as methane, propane, butane, ammonia, carbon monoxide and many others (please see back of manual for a more complete list). Even low levels of combustible gas can be detected in seconds.

The GSM100 detects gas concentrations through the use of an internal sensor. This sensor is heated during operation. As the heated sensor interacts with gases, the unit immediately indicates to the user that combustible gases are present. The GSM100 indicates the presence of combustible gases with visual, audio and vibration feedback mechanisms. There are five (5) threshold levels of measurement within two (Low and High) settings of sensitivity. When the tool senses the presence of a combustible gas, it will tell the operator by blinking the appropriate light(s), triggering the appropriate audible alert or providing the appropriate vibration alert.
The GSM100 comes equipped with an attached flexible 16″ probe hose.

Combustible Gas Detector Safety

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.

Charging and Installing Batteries

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.

In case of unnecessary danger, it is not allowed to charge or replace batteries in the concentration of combustible gas. Set up and operate the gas detector according to these procedures to reduce the risk of fire, explosions and serious injury and incorrect measurements.

The GSM100 has an internal rechargeable battery. If the battery is low, use the 5V/0.5A adapter to charge. Please remove the battery in case battery leakage before long-term storage or transportation.

In the concentration of combustible gas, it is not allowed to replace the batteries or use the adapter, in order to reduce the risk of explosion, fire or other serious injury. It is not allowed to operate when charging.

Pre-Operation Inspection

Warning

Before each use, inspect your GSM100 and correct any problems to reduce
the risk of injury or incorrect measurements.

Clean any oil, grease or dirt from equipment. This aids inspection.
Inspect the GSM100 for any broken, worn, missing, misaligned or binding parts, or any other condition which may prevent safe and normal operation.
Check that the warning labels are present, firmly attached and readable.
If any issues are found during the inspection, do not use the GSM100 until it has been properly serviced.
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 it has been properly serviced. Remove the gas source and allow several minutes for the sensor to stabilize prior to use.

Set-Up and 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.

Operation

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 all equipment has been 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 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) sensitivity lights are ON at the same time, this indicates that the batteries need to be charged. 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 ten minutes with no activity and Auto Power Off is enable, it will automatically shut OFF to conserve the batteries.
The Audible Alert and Vibration Alert retain the previous state the detector was last in and can be turned ON or OFF if desired. 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 Alert button to turn it ON and OFF. The gas detector will vibrate twice when turning the Vibration Alert ON and vibrate once when turning the Vibration Alert OFF.
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 1for information on methane concentration levels and gas detector feedback.
When the gas detector is turned ON it is in whatever sensitivity state it was last in. In the low sensitivity setting, the lowest concentration of methane detected is 100 ppm. Switch the sensitivity 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 Sensitivity (L) buttons. If locating a leak, use the gas detector to find areas of lower gas concentration and follow back to the source. In a piping system, trace the system, stopping at the joints to monitor the gas levels.
When gas detection is complete, turn the GSM100 OFF by pressing the ON/OFF button.
