Segments
A“Segment”firestoatargettemperature.Itincludesarate
and, if needed, a hold. Every time you need to change firing
speed or hold a temperature, add another segment. You have
up to eight segments available in a User Program. You don’t
have to use all eight segments—only the number needed per
firing. Often one segment is all you will need.
For complex firings, Ramp-Hold can be fired in 16 seg

Maximum rate is 9999. When you enter 9999, the controller
will heat as fast as your furnace or kiln is capable.

firing adage: “When in doubt, slow it down.”

Wearing firing safety glasses, watch the pyrometric cones
on the shelf near the end of the firing. When the shelf cone
bends, note the hold time. The next time you fire the same
