During the RH Dwell stage, the air is circulated inside the chamber. Additional humidity
will not be added during this stage, so do
NOT
open the Main Door or the CA Chamber
Door.
After the RH Dwell stage is complete (or after the Humidity Stage is complete, if no RH
Dwell stage was selected), the program will move to the Fuming stage. The screen will
display the following information (see Fig. 6-15) during this stage:
When the Fuming stage begins, both the Main Door and the CA Chamber Door will
lock. They remain locked until the program is complete. This prevents opening the
doors once CA fumes are present. If a power outage occurs while the doors are locked,
they will remain locked. See
Section 10: Troubleshooting
for instructions to manually
override the Main Door Lock so that evidence can be removed to protect it from over-
fuming.
The Stage Time shown during the Fuming Stage is from the beginning of the stage, or
when the Hot Plate begins to heat, not when the Hot Plate reaches the desired
temperature. The Fuming Stage is dependent only upon the Stage Time entered in the
program parameters, and will end when the Stage Time is reached. The Hot Plate
temperature will increase until the program parameter set point is reached, and maintain
that temperature, within 10
O
F (5
O
C), until the Fume Stage is complete. If evidence
begins to over-process, before the Fuming stage is complete, you can press
[STOP]
or
[PURGE]
. Once the Fuming stage begins, pressing
[STOP]
will initiate a 5 minute
purge (same as pressing
[PURGE]
) to remove CA fumes from the chamber. Note
– if
you press
[STOP]
before the Fuming stage begins, the unit will stop without purging.
If evidence is not processed enough as the end of the Fuming stage nears, you can add
more time to the Fuming stage. However, you must add time before the Fuming stage
ends. Once the Purge stage begins, no more time can be added.
