3.3.2 MEASUREMENT
This screen is used to choose the measurement display mode—instantaneous, average, synoptic, or
graphic—to activate the real-time printout and to display possible alarms.
3.3.2.1 MEASUREMENT

Instantaneous
Definition of keys specific to this screen:
[Sample]
Selects the sample gas inlet. The gas is continuously sampled through the inlet dust filter.
Measurement mode, unit, and range are chosen in the «
CONFIGURATION »
menu and in
its corresponding submenus. This mode can be interrupted at any time by starting an
automatic cycle or by manually selecting another mode or another gas inlet (zero or span).
[Zero]
Selects the zero gas inlet. Allows manual control of the zero on the zero filter. The value of
the zero (possibly increased by a programmed offset) is displayed on the screen.
This operation allows checking the analyzer’s zero air response, estimating its stability over
time, and determining the necessity of a zero reference cycle.
[Span]
Selects the span gas inlet. Allows manual control of the span. The measured span gas
value (possibly increased by a programmed offset) is displayed on the screen.
This operation allows checking the stability and the drift of the span reading to determine
the necessity of launching an auto-calibration cycle or programming its repetition period.
