
Synoptic
This screen represents the physical measurement components of the instrument and displays the
measurement channels values of the operation parameters.
The [Start] key enables to start the cycles programmed in the « CONFIGURATION

mode » menu. The [Stop] key, which is displayed instead of the [Start] key after the cycle starting,
must be used to stop the current cycle.
(1) values of the first three channels, with the corresponding units. The [>>] key enables to display the
three following channels, according to the programming carried out in the «

Measure channels » menu.
(2) date and hour,
(3) sample air inlet,
(4) source holder assembly, (5) radioactive source: diagrammed into this position, the source is said
“out of gear”: it means that the analyzer is not into measurement mode,
(6) reel of filter ribbon, (7) number of measurement cycles which the analyzer can make, this (N) value
indicates the number of available sampling spots remaining.
(8) pressure panel block and Geiger Muller counter, (9) fluid circuit diagram, (10) critical orifice, (11)
control valve assembly, (12) P1 pressure upstream the critical orifice, (13) P2 pressure downstream
the critical orifice: when the analyzer starts up, P1 and P2 are at atmospheric pressure,
(14) atmospheric pressure, (15) ambient temperature, (16) internal temperature of the analyzer, (17)
relative atmospheric humidity, (18) temperature of the sampling tube (RST line).
