3.7 Description of the parameters, and their limitations.
As a useful guide, we have listed for you in Table below, the parameters, their functions
and their limits. The comments will draw your attention to other relevant details.
The starting temperature of the program. When it is reached the
cycle will begin.
One of the parameters, which have to be included in order for a
program to run.
The time required to raise the platform from lowest position until
the muffle is closed.
During UP TIME the platform rises in four progressive stages.
The final stage of the UP TIME during which the muffle is closed
and the temperature does not rise for the defined duration.
1. Vacuum pump will start pumping out the air before the DRY TIME
countdown begins.
2. If DRY TIME without vacuum required , VACUUM START temperature
value should be 5C higher than START TEMP.
The rate in C or F at which the temperature rises from START
TEMP to HIGH TEMP and from HIGH TEMP to FINAL TEMP.
One of the parameters which have to be included in order for a
program to run..
The temperature to be reached at the end of the HEAT RATE or
intermediate temperature when the value of the FINAL TEMP is
higher
100C to 1100C in normal
1. Must not be less than “VACUUM OFF” temperature. (When a vacuum
is included in the program).
2. One of the parameters which have to be included in order for a
program to run.
The duration of time that the furnace will remain at the HIGH
TEMP before the firing chamber is opened or before the
temperature will continue it’s rise to FINAL TEMP (if defined) .
0 to 30 minutes (specified in minutes and seconds).
0 to 4:30 H in the HT Programs
1. Intermediate delay when FINAL TEMP is higher than HIGH TEMP.
