Cause
The readings are excessively
high.
Calibration with the ambient
air failed.
The device is operating out-
side the recommended tem-
perature range.
The refrigerant sample has a
very high content of air or the
amount of refrigerant was too
low for testing.
Troubleshooting
Remedy
Keep possible electrical
sources of interference, such
as mobile phones or welding
equipment, away from the
device.
Ensure the device is ade-
quately ventilated.
Leave any leaking refriger-
ant to drain off.
Only use the device in tem-
perature-controlled rooms
(10 °C – 45 °C).
Ensure sufficient ventilation.
Make sure that there is
enough refrigerant pressure.
Make sure that all the hoses
are connected, not kinked
and free of oil.
