/ 5
A fast rate (above diagram) can cause the temperature to
over-shoot the target temperature.
The simplest solution to temperature over-shoot is to
slow the rate, as in diagram above.
Another solution to temperature over-shoot: in
Ramp-Hold (select the ProG prompt), add a segment with
a slower rate, to begin approximately 40° - 60° below the tar
-
get temperature.

Firing Instructions
Note: Single Segment firing is all you will ever
need if you are enameling or firing silver clay.
1 From IdLE , press START.
2 Use the Up Arrow key (not the Down Arrow)to
select a firing rate (temperature rise per hour)
from 1 through 5:
SPd1 / (200°F or 111°C)
SPd2 / (500°F or 277°C)
SPd3 / (1000°F or 555°C)
SPd4 / (1500°F or 833°C)
SPd5 / (Full Power)
ProG (Selects Ramp-Hold mode: see next page.)
Then press START.
3 °F or °C and the target temperature from the
last firing will appear. Use the arrow keys to
change the target temperature. Then press
START.
4 HLd and the hold time from the last firing will
appear (e.g. 1 hour 10 minutes = 01.10). Use the
arrow keys to change the hold time. Then press
START.
5 Strt will appear. Press START to begin firing.
-On- will appear, the Run indicator light with be-
gin blinking, and the kiln will begin firing.
To stop a firing before completion, press
START/STOP. StOP will appear, alternating with kiln
temperature.
Note: Do not be concerned if your kiln makes a
clicking sound during firing. Kilns use relays to
power the elements. The relays click each time
their electrical contacts come together.
Note: The firing speed you select (see step 2) is
a pre-programmed speed. The kiln’s actual fir
-
ing speed may be less, depending on the kiln
model, available voltage, and density of load you
are firing.
When the kiln fires to completion, the controller will
beep for 30 seconds. The display will show the following:
I
Firing time
I
Present temperature

To return to IdLE , press START.
Rate
Each segment must include a rate, which is degrees of
temperature change per hour. Single Segment mode has
only one rate.
The kiln will fire at full power when the rate is
1799°F/999°C. Full power displays as FULL .
Note: To enter full power from 0000 , press the
Down Arrow key once.
Temperature Over-Shoot
When a kiln is heated too fast, it may over-shoot the target
temperature, especially in small kilns at lower temperatures.
To avoid this, add an extra segment to slow the firing. If you
experience over-shoot in Single Segment mode, either slow
the rate, or use Ramp-Hold to add a slow segment near the
target temperature.
