Greenlee HRCG-300 Manual De Instrucciones página 6

Operation
1. Verify that the sensor and tip are unobstructed and that a filter is in place.
2. In a fresh air environment, press the POWER button. LEDs illuminate to indicate the relative battery
power. Allow 10 seconds for the unit to stabilize and zero out background vapors or gases. The
LEDs illuminate and the audible indicator beeps rapidly and briefly at the end of the warm-up.
During the warm-up period, the unit has zeroed out any concentrations of gases that were present
in the area.
3. Test the unit with the corresponding gas.
• If the unit does not function as expected, replace the batteries or filter.
• If the unit still does not function as expected, send the unit to Greenlee for repair.
4. Move the probe slowly toward the area where refrigerant or combustible gas may be present.
Notes
• Pressing the MUTE button silences the unit.
• When the battery is low, the LO BATT LED illuminates. The unit will function for approximately 20
more minutes.
• Middle LEDs illuminating steadily may indicate that the sensor is flooded with gas, or that the sensor
has failed. Flush the sensor with fresh air for one minute. If middle LEDs remain illuminated, the
sensor is depleted or faulty. Replace the sensor as instructed under Installing the Sensor in this
manual.
• Erratic indications, slow response times, and any other faulty results also indicate that the unit
needs repair.
• Do not expose the refrigerant sensor to a steady stream of highly concentrated refrigerant.
Sensor life is proportional to the amount of refrigerant that passes through it.
• Exposing the combustible gas sensor to a high concentration of combustible gas may
temporarily make the detector less responsive to lower gas levels. If this occurs, move the
detector to an area of fresh air for several minutes to purge the sensor of the gas.
Failure to observe these precautions can result in damage to the sensors.
