Example:
If your porcelain appears to be overfired by 25°,
you would enter a negative (-25) twenty-five degree value to
lower the effective firing temperature of ALL the Low Fusing
program.

The display will show the current Low Fusing porcelain
calibration offset. For new furnaces this should be “0”. If
the Selector Knob is rotated clockwise note that the “0”
value changes to a positive value, and if rotated counter-
clockwise it changes to a negative value. If you need to
raise ALL your Low Fusing program firing temperatures by
the same amount you can dial in a positive value then press
the
Next
button to accept the offset value. Conversely,
if you want to lower ALL your Low Fusing program firing
temperatures by the same amount, dial in a negative value
and press the
Next
button to accept the offset value.
