display, the dot disappears.
Right-Hand Dot: °C
When temperature
is displayed in °C, a dot

Thermocouple Inspection
The small rod protruding into the firing chamber is the
temperature sensor, or thermocouple.
CAUTION: Bumping the thermocouple can push it
out of the firing chamber. This could cause an overfire!
The controller does not contain an alarm to detect this
type of failure. Bumping the thermocouple could also
cause inaccurate readings.
I
A 1/8” diameter thermocouple should extend into the
firing chamber ½” - 5/8”.
I
A ¼”diameter thermocoupleshould extendinto the fir
-
ing chamber 1” or more.
I
Keep shelves, posts and ware 1” - 1 ½” away from the
thermocouple.

Scroll Numbers
During programming, hold an arrow key down several
seconds, and numbers will begin to scroll rapidly. Ordi
-
narily, you would press to raise a number and
to lower it. But sometimes it is faster to press
the opposite key. This is because the numbers scroll below
0000 to the highest number, and vice versa. Examples:
I
To program a 99.59 hour Hold when the display shows
00.00, press the once.
I
To program a FULL rate when the display shows 0000,
press the once.
I
To program a temperature of 200°F when the display
shows 1800°F, press the . That is faster than
pressing the .
Program Review &
Repeat Firing
Program Review lets you check that the information
programmed into the controller is correct. It is a good habit
to use Program Review before every firing. Program Re-
view shows the values for the program in active memory,
which is either—
The program that was fired last.
The program that was selected since the last firing.
I
Press the
key. The rate, temperature, hold, etc. will display
one after the other. Firing will continue.

Delay is a count-down timer. The kiln begins firing when
the timerruns out of time. Use Delay to fit a firing into your
schedule.
CAUTION: For safety,donot leave thekiln alone dur
