Error Codes
ERR.2
Signifies internal sensor failure due to temperature extremes.
Corrective Action for Error 2:
1. Allow the unit to stabilize at room temperature for at least 30 minutes.
2. To clear the error code, unplug the instrument. The error code will be cleared at the
next power-up.
ERR.3
Signifies a calibration fault.
Corrective Action for Error 3:
1. Verify the purge vent hose is not directed towards the instrument, and the air intake
port and the sample exhaust ports are not obstructed.
2. If the instrument is being used in small, closed areas, refrigerant vapors can build up
in the surrounding atmosphere. These vapors are drawn into the air intake port during
calibration and will cause a fault. Move the instrument to a location with fresh, ambient
air free of refrigerant vapors. Use the instrument in locations that provide adequate
ventilation to prevent the accumulation of refrigerant vapors.
3. To clear the error code, unplug the instrument. The error code will be cleared at the
next power-up.
