Fault symptom Causes / Solutions
CO2 too low • Air leaking into probe, tubing, water trap
or connectors.
CO2 reading (- - - -) • Meter was stored in a cold environment and
is not at normal working temperature.
Batteries not holding charge • Batteries exhausted.
Meter does not respond to flue gas • Particle filter blocked.
• Probe or tubing blocked.
• Pump not working or damaged with
contaminants.
Net temperature or Efficiency • Ambient temperature set wrong during
calculation incorrect. Automatic Calibration.
Flue temperature readings erratic • Temperature plug reversed in socket.
• Faulty connection or break in cable or plug.
T flue or T nett displays (- - - -) • Probe not connected or faulty
X-Air, EFF display • CO2 reading is too low.
