Auto dilution

If the dilution stage
auto-dilution
is selected, dilution (5x) is
activated automatically when the set switch-off threshold of the
sensor in slot 6 is reached.
• If the surrounding air contains interfering gases, push
the hose onto the dilution inlet and place in a clean
atmosphere.
• If gas from a gas cylinder is used, observe a max.
pressure of 30hPa
• Diluting also changes the resolution of the reading
display, e.g.:
Undiluted resolution 1ppm, with factor 10 resolution
10ppm.

Measurement range extension with fixed dilution factor (x5) for

sensors (x5). The measuring channels O

. 1x deactivates the
dilution (extension of measuring range).
It is possible to calibrate / adjust with test gas when dilution is
switched on to eliminate any measuring errors caused by dilution
(see Calibration / adjustment page 61).
