2. Safety Information

Always observe the following safety precautions to prevent injury or damage to the devices.

2.1 General Safety

• Do not attempt to disassemble or modify the devices.
• Keep the devices away from water, dust, and extreme temperatures.
• Use only the specified battery type (AAA batteries for the gas detector).
• If the device is damaged, do not operate it. Contact customer support.

2.2 MESTEK CGD02A Combustible Gas Leak Detector Safety

• This device detects combustible gases. It is not designed to detect toxic gases like carbon monoxide (CO) unless specifically listed as a combustible gas.
• Do not rely solely on this device for personal safety in hazardous gas environments. Always follow local safety regulations and use appropriate personal protective equipment.
• Ensure proper ventilation when investigating gas leaks.

2.3 MESTEK IR02C Infrared Thermometer Safety

• Laser Safety: Do not stare directly into the laser beam or point it at people or animals. The laser is used for targeting only and does not measure temperature.
• Avoid using the thermometer near strong electromagnetic fields.

• K-type thermocouple contact measurement range: 14°F to 932°F (-10°C to 500°C).
• Adjustable emissivity (0.10 to 1.00).
• 13 laser pointers for precise targeting.
• Color LCD display with backlight.
• High/Low temperature set alarm function.
• Humidity and ambient temperature display.
• °C/°F conversion.

Components:

• IR02C Infrared Thermometer unit
• K-Type Thermocouple Probe
• Carrying Pouch
• AAA Batteries (2pcs, typically)
• User Manual

4. Setup

4.1 Battery Installation

Both devices require AAA batteries for operation. Locate the battery compartment on the back of each device. Open the compartment cover, insert the batteries according to the polarity indicators (+/-), and close the cover securely.

• CGD02A Gas Leak Detector: Requires 3 x AAA batteries.
• IR02C Infrared Thermometer: Typically requires 2 x AAA batteries.

5. Operating Instructions

5.1 MESTEK CGD02A Combustible Gas Leak Detector

5.1.1 Power On/Off and Calibration

1. Press and hold the Power button to turn the device on.
2. The device will perform an automatic calibration for approximately 30 seconds. Ensure the probe is in a clean air environment during this process.
3. Once calibration is complete, the device is ready for use.
4. To turn off, press and hold the Power button again.

5.1.2 Gas Detection Procedure

1. With the device powered on and calibrated, slowly move the flexible probe towards the suspected area of a gas leak.
2. Observe the LCD display for gas concentration readings (PPM or %LEL).
3. If a gas leak is detected, the device will emit an audible alarm and the screen will display visual warnings (e.g., 'HIGH' for concentrations above 10000 PPM or 20% LEL).
4. The flexible probe allows detection in hard-to-reach areas such as pipes, joints, and appliances.

5.1.3 Unit Switching and Automatic Power Off (APO)

• Press the °C/°F button to switch between Celsius and Fahrenheit for ambient temperature display.
• Press the PPM/%LEL button to toggle between Parts Per Million (PPM) and Percentage of Lower Explosive Limit (%LEL) for gas concentration readings.
• The device features a 10-minute automatic shutdown function to conserve battery life. This can typically be disabled by pressing the APO button, though specific instructions may vary.

5.2 MESTEK IR02C Infrared Thermometer

5.2.1 Power On/Off and Non-Contact Measurement

1. Press the Trigger to turn on the device.
2. Point the thermometer at the target object. The 13 laser pointers will indicate the measurement area.
3. Press and hold the Trigger to take a continuous reading. Release to hold the reading on the display.
4. The device will automatically power off after a period of inactivity to save battery.

5.2.2 K-Type Thermocouple Measurement

1. Insert the K-type thermocouple probe into the designated port on the side of the thermometer.
2. Place the tip of the K-type probe in direct contact with the object whose temperature you wish to measure.
3. The display will show the contact temperature reading.

5.2.3 Mode Selection and Settings

Use the MODE button to cycle through various settings and functions:

• Emissivity Adjustment: Adjust the emissivity (ε) value (0.10 to 1.00) to match the surface being measured for more accurate non-contact readings. Use the Up/Down arrows to change the value.
• High/Low Temperature Alarms: Set upper and lower temperature thresholds. If the measured temperature exceeds or falls below these limits, an alarm will sound.
• °C/°F Conversion: Switch between Celsius and Fahrenheit temperature units.
• Humidity Display: The device displays ambient humidity.
• Ambient Temperature: The device displays the surrounding air temperature.
