The Analysis Graph screen gives information on the current analysis in progress, and allows the user to
monitor the progression of the analysis. This screen gives information on:
-
The current atmospheric pressure, measured in kPa (e.g. 101.5 kPa).
-
The microgram per liter un-calibrated (µgu) data from the analysis, for example TICµgu or TOCµgu
without any compensation for atmospheric pressure.
-
The height of the CO
2
peaks in each phase of the reaction (e.g. 956ppm CO2).
-
The current MFC flow in l/h (e.g. 10.0 l/h).
-
The temperature of the analyzer in °C (e.g. 26°C).
-
The CO
2
instantaneous value (e.g. 56ppm CO2i) and the CO
2
zero value (e.g. 12ppm CO2z) of the
reaction.
-
The elapsed time (e.g. 265s) since the start of the analysis.

If the Reagent Status screen has been activated, the estimated number of days left for each reagent type is
shown on the display.
If the reagents run low, a LOW REAGENTS fault is activated. This fault has to be cleared by resetting the
reagent level in the Install New Reagents menu.
Note that the LOW REAGENTS fault can be set as a warning (where the common fault relay will activate) or a
notification, in which case a special programmable relay is required to signal the LOW REAGENTS condition.
