ERROR CODES AND CORRECTIVE ACTIONS
The instrument is supplied with self-diagnostic software to aid in
determining problems. The software will supply error messages that
direct the user toward specic corrective actions in the event of system
failure. Should corrective measures not correct the problem, the user is
advised to contact Robinair at 1-800-822-5561 for assistance.
SAMPLE FAULT: Signies unstable infrared readings due to
inconsistent sample gas supply or interference from strong electrical
elds.
Corrective Actions:
1. If the error code occurs during a sample cycle, verify the sample
hose is receiving sample gas from the source connection of at least
5 psig. Verify the instrument sample exhaust port and air intake
port are not clogged or restricted.
2. If the error code occurs during a calibration cycle, verify the air
intake port and sample exhaust port of the instrument are not
clogged or obstructed.
3. Keep the unit away from sources of strong electrical elds, such as
large compressors, running vehicles, etc. Move the instrument 3–5
feet away from the electrical eld source, and try again.
4. If the instrument is being used outside of the operating temperature
range of 39–122°F (4–50°C), allow the instrument to warm or cool
to the operating temperature range, and try again. The instrument
may require additional warm-up time after “power up” before use.
5. To clear the error code, power down the instrument. The error code
automatically clears.
