the production mixture. Burn the test sample until it is clean
(free of coke, the solid binder residue).
NOTE
Using the Auto-Control with cutoff limit of 0.01% or
0.1 g will accomplish a clean burn test sample.
Use the time required to produce a clean test sample as the burn
time. This lists the minimum recommended burn times for
selected sample masses.
To program the burn time manually, press
(2) at the Burn
Parameter Menu shown on page 5-4. The oven requests the
burn time between 15 and 720 minutes. Use the numeric keys to
set the burn time. To move the cursor back one position, press
the
(BACK SPACE) key. When finished, press (ENTER). The
oven sets the new burn time, displays a brief confirmation
message, and returns to the Burn Parameter Menu.
NOTE
The oven will not store burn data for burn times
greater than 120 minutes. Burn data storage is
available only for burn times of 120 minutes or less.
Cutoff Limit
In the Auto-Control burn mode, the oven adjusts the burn time
according to the cutoff limit. The cutoff limit can be defined in
grams or as a percentage of the initial sample mass. When the
change in the sample mass is less than the cutoff limit for three
consecutive minutes, the oven completes the burn cycle.
