Dilutable gases and the actual values (2):
This show the
dilutable gases and the calculated undiluted actual gas
concentration value (C
pure
).
d. To fine calibrate the dilution-unit select the dilutable gas and
impinge the analyser with the calibration gas. Wait until the gas
concentration will not change anymore. Shift with the right/left
arrow keys the dilution factor, until the actual value has the gas
concentration of the calibration gas cylinder.

Threshold: The operator can change the threshold. If the value is above this
threshold, the dilution will turn on.

Setting the dilution cycle
In the default setting the dilution is set automatically. This means, the first cycle will
be measured dilute. If the gas concentration is under the threshold, the next cycle
will be measured undiluted. If the sample gas concentration will reach the
threshold again, the dilution will be activated. During the activation, the
measurement value will be hold for 90 sec. At the display, the dilute measurement
-values will turn on
again.
