Contamination Check (page 5-
60)
for more information.
The Residual Contamination
Check is run under the following
circumstances:
- Following any door violation.
- If the Residual Contamination
Check before Background Check
option is set - see
Options (page
5-6) .
- If Residual Contamination
Check after Alarm option is set -
see
Options (page 5-6) .
The Residual Contamination
Check will verify that the current
background count rate does not
exceed the Background Count
Rate before the alarm, by a
statistically significant amount.
If no contamination is found, the
"Ready – OPEN DOOR TO
MONITOR ARTICLES"
message is displayed and the
SAM12 reverts to Background
mode.
However, if residual
contamination is detected or the
count rate from any detector
exceeds 95% of the Amplifier
“dead-time”, then an Instrument
Contaminated state exists. The
"INSTRUMENT
CONTAMINATED – DO NOT
USE" message is displayed (see
Instrument Contaminated (page
5-61)
for more information).
Note that if the Door Locked
options are ticked, the door(s) are
locked while the Instrument is
Contaminated.
See
Doors (page 5-13) for more
information regarding Lock Front
Door on Alarm.
