WARNINGS

To ensure the safe operation and service of the tester, follow these instructions. Failure to observe these warnings can result in severe 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 gases.
• Initial calibration should be performed in an area known to be free of refrigerant gases. Calibration in an area containing refrigerant gas will result in incorrect calibration and lower than actual readings. This could result in refrigerant gases not being detected.
• The refrigerant gas leak detector is NOT intended as a personal protection device (PPE).
• The refrigerant 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.

  Press to enable or disable the Auto Power-Off feature. When enabled, the button will illuminate blue, and the tester will automatically power off after 10 minutes of inactivity.

• LOW BUTTON 10
  Press to enter Low Sensitivity mode (200 to 3,000 ppm). White light will blink.

• HIGH BUTTON 11
  Press to enter High Sensitivity mode (100 to 1,000 ppm). Yellow light will blink.

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

• POWER BUTTON 13
  Press and hold for 3 seconds to turn tester on or off.

OPERATING INSTRUCTIONS

1. In an area where 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 (blue) 4 blinks. Once complete, all indicator lights 4 5 6 will blink for one second, then the HIGH indicator light 6 will illuminate and continue to flash, indicating it is ready to take a measurement.

2. Start measuring in the High sensitivity mode (100 to 1,000 ppm). To view higher values (200 to 3,000 ppm), press the LOW button 10 to enter Low sensitivity mode.

3. Point the sensor 3 towards the area to test. If all blue indicator lights are illuminated in High sensitivity mode, switch to Low sensitivity mode by pressing the LOW button 10 .
   NOTE: Changing from High to Low sensitivity mode may cause some of the indicator lights to turn off.

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 refrigerant gases can cause 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 the LOW alert 5 and HIGH alert 6 lights are illuminated at the same time, the batteries must be replaced.

1. Loosen screw and remove battery door 15 .

2. Remove battery cartridge 16 from battery compartment.
   Note orientation.

3.  Remove and recycle spent AAA batteries.

4. Install 4 new AAA batteries into cartridge, noting proper polarity.

5. Place battery cartridge back into the battery compartment, aligning the leads (fits only one way).

6. Replace battery door and tighten screw securely.

SENSOR SERVICING
When ALL lights on the tester 4 , 5, 6 , 7, 9 are illuminated, the sensor 3 has failed and the unit must be serviced. Contact Klein Tools at 1-800-553-4676 or customerservice@kleintools.com for further details. There are no user- serviceable parts inside tester.
