WARNINGS

To ensure safe operation and service of the tester, follow these instructions. Failure to observe these warnings can result in severe injury or death. High concentrations of combustible gasses 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.

• Read, understand, and follow all instructions to ensure safe operation.
• Always turn on the gas detector in an area known to be free of combustible gasses.
• Initial calibration should be performed in an area known to be free of combustible gasses. Calibration in an area containing combustible gas will result in incorrect calibration and lower than actual readings. This could result in combustible gasses not being detected.
• The combustion gas leak detector is NOT intended as a personal protection device (PPE).
• Do NOT replace batteries in an explosive atmosphere.
• The combustion gas leak detector is NOT insulated. Avoid contact with areas where energized conductive elements may be present. Shut off power to the area before starting measurements.
• Do NOT probe moving machinery that could catch any part of the meter and cause harm to the operator and the meter.
• Always wear approved eye protection.

FUNCTION BUTTONS

1. AUTO-ZERO BUTTON 7
   Press to set zero point in a known clean environment.

2. MUTE BUTTON 8
   Press to mute the audible alarm. Visual indicators will continue to function as normal.

3. AUTO POWER-OFF (APO) BUTTON 9
   Press to enable or disable the Auto Power-Off feature. When enabled, the tester will automatically power off after 10 minutes of inactivity.

4. LOW BUTTON 10
   Press to enter Low Sensitivity mode (1,000 to 10,000 ppm).

5. HIGH BUTTON 11
   Press to enter High Sensitivity mode (50 to 1,000 ppm).

6. HOLD BUTTON 12
   Press to lock the current measurement on the screen. Press again to return to taking active measurements.

7. POWER BUTTON 13
   Press to turn tester on and off.

OPERATING INSTRUCTIONS

1. In an area where combustible gas is known to be not present, press the power button 13 for 3 seconds. The tester will beep and start a 50-second zero-calibration process while the first indicator light blinks 4. Once complete, all indicator lights 4 will blink for one second, then the HIGH 6 indicator light will illuminate and continue to flash, indicating it is ready to take a measurement.

2. Start measuring in the High sensitivity mode (50 to 1,000 ppm). To view higher values (1,000 to 10,000 ppm), press the LOW button 10 to enter Low sensitivity mode.

3. Point sensor 3 towards the area to test. As all indicator lights are illuminated in High sensitivity mode, switch to Low sensitivity mode by pressing the LOW button 10 .
   NOTE: This may cause most of the indicator lights to turn off. In Low sensitivity mode, concentration levels are measured in larger intervals than in High sensitivity mode, meaning greater concentration levels are required to illuminate each indicator light.

4. As you get closer to the source of a leak, the concentration levels detected will increase, as indicated by increasing audible/visual alarms. Move the sensor head in the direction of increasing audible/visual alerts to the source of the leak.
   WARNING: High concentrations of combustible gasses 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.

MAINTENANCE

BATTERY REPLACEMENT
When both the LOW alert light 5 and HIGH alert light 6 are illuminated at the same time, the batteries must be replaced.
WARNING: Do NOT replace batteries in an explosive atmosphere.

1. Loosen the screw and remove battery door 15.
2. Remove battery cartridge 16 from the battery compartment. Note orientation.
3. Remove and recycle 4 spent AAA batteries.
4. Install 4 new AAA batteries into the cartridge, noting proper polarity.
5. Place the battery cartridge back into the battery compartment, aligning the leads (fits only one way).
6. Replace the battery door and tighten the screw securely.

SENSOR SERVICING
When ALL lights on testers 4, 5, 6, 7, and 8 are illuminated,  sensor 3 has failed and the unit must be serviced. Contact Klein Tools at 1-877-775-5346 or [email protected] for further details. There are no user-serviceable parts inside the tester.
