3BUS 208 000 R1301 133Measurement Setup
Figure 6-12 on page 134 describes the standardize CLEAN/DIRTY mode selection
that takes place when a standardize is requested from either the Host, the Health
Reports (HP), or the Frame Control Panel (FCP). To summarize the three situations,
whenever DIRT standardizes occur and are accepted by the sensors; the OptiPak
sensor can be set up to basically ignore standardize requests, the Basis Weight sensor
will take into account the effect on beam absorption when dust accumulates on the
window, and the GT Caliper sensor will filter the sensor zero (SZERO) results for
GT Caliper to adjust for the effects caused by dust on the probes.
Standardize initiated from the Frame Control Panel (FCP) is either CLEAN or
DIRTY depending on the state of the instance variable localStdzMode in the object
fhi01. The default setting for this variable is DIRTY. This can be changed to be
CLEAN by changing the value from a "0" to a "1" (if this change is to be retained
after a system reset, the "fhi" graph needs to be saved with the gstore utility). A
reset is NOT needed to make the change active.
In any CLEAN standardize request, an automatic internal check sample for those
sensors so equipped, is executed.
Note: Three sensor categories require a "good" CLEAN standardize before
they can be made operational after a restart. These are the OptiPak
(FOB), Caliper sensor, and ALL Basis Weight sensors. After a
restart, and regardless of which kind of standardize is being
requested from the host, Frame Control Panel, or Health Reports,
a CLEAN standardize will be scheduled for these sensors until the
initial standardize is passed. The individual sensor manuals should
be consulted to see the effect of a CLEAN or DIRTY standardize
selection.
