Data display (3 digit numeric display)
Measured value, warm-up time countdown, cal request, idling operation, ect.
Bar graph indicator (0 to 200% in 20 segments)
Measured value, cal gas pressure – if equipped with auto cal function (indicated during warm-up and during
calibration), sensor sensitivity (at cal completion), etc.
Malfunction alarm display
“AIR FLOW” (measured gas intake flow), “CAL FAIL” (EE Prom failure, calibration gas pressure low, unable to
calibrate)
