Cone Offset

CONE OFFSET - GENESIS

Turn kiln ON with toggle switch
Press MENU
Press # 3 - ADJUSTMENTS
Press # 1 - CONE OFFSETS
Press EDIT
Use the scroll to the right to select the cone you are offsetting.
Enter the degrees you would like to offset your cone. (if negative, make sure to put - symbol before the number)
Press BACK to return to the main menu screen

Tune your kiln using the Thermocouple Offset for your most critical firing (typically glaze firings).
Typically, bisque firings are not very critical.
CNOS (Cone Offset) - is used to fine-tune what the DynaTrol thinks the final cone temperature should be in EASY-FIRE programs. The final cone temperature can be raised or lowered to a maximum of 99°F (or 55°C). When entering the offset temperature, the following code is used: the left two digits designate whether to raise (00) or lower (90) the cone temperature; that is, “00” means plus (+), and “90” means minus (-). The right two digits are the number of degrees the cone temperature will be raised or lowered. This offset will remain programmed only for the specific cone number until you reprogram the cone offset differently

Examples:

Number	Meaning
0020	Raise the final cone temperature by 20°F
0040	Raise the final cone temperature by 40°F
9030	Lower the final cone temperature by 30°F
9005	Lower the final cone temperature by 5°F

NOTE: This option does not affect the VARY-FIRE (Ramp-Hold) mode but it will show up on the menu.

NOTE ABOUT PREPROGRAMMED CONE OFFSETS:

The Cone Offsets come preprogrammed. From cone 022 to cone 017 the cone offsets are set at 9020. All other cones are preset at 0000.
Note on Blue DynaTrols made before Oct 1 2004, the cone offset was 9030 for cones 022 to 017 and 9020 for other cones. (The offsets were changed when we switched to a more responsive thermocouple protection tube).
You can always change offsets.
The RESET option in Other menu will NOT reset these cone offset settings.
This is part of the compensation necessary for the mullite thermocouple protection tubes.

OTHER OTHER	CNOS	If CNOS does not show on the display, press the Other key until CNOS displays.
ENTER	Alternately flashing: CONE & #	Cone Offset has been selected; the word CONE and the last entered cone number will alternately flash on the display. Now enter the cone number which you want to adjust (in this example cone 07)
07	Alternately flashing: CONE & 07	The word CONE and the entered cone number (07) will alternately flash on the display. If you type a wrong number, press 0 three times, press ENTER, then type the correct number.
ENTER	Alternately flashing: °F0S & 0	°F0S and the previous offset setting alternately flash. Enter the new offset temperature using the rules above, in this example, 9020
9020	9020	The selected offset temperature is displayed. If you type a wrong number, press 0 four times, then type the correct number.
ENTER	IdLE flashes then the current temperature	IdLE indicates the offset temperature adjustment has been accepted. The current temperature then flashes in the display.
