Read oil temperature.
Insert the fry vat probe of the
pyrometer into the hot oil to
within 1 inch (2.5 cm) of the
probe’s tip. The tip should
be approximately 3 inches
(7.6 cm) below the surface of
the oil. Allow the temperature
reading to stabilize.

Display temperature on fryer.
Press the temperature display
switch for the vat where you
took the pyrometer reading.
The display will show the
temperature for the vat.

Compare temperature
readings.
Compare the temperature
reading on the pyrometer with
the corresponding tempera-
ture on the display.
If the two temperatures are
less than 5°F (3°C) apart (ei-
ther plus or minus), you do
not need to adjust the tem-
perature setting.
If the two temperatures are
more than 5°F (3°C) apart
(either plus or minus), call a
service technician to report
the problem.

Repeat for other side of split-
vat.
If the vat you tested was a full
vat, skip this step and go to
step 9.
If the vat you tested was one
side of a split-vat, repeat steps
5 through 7 on the other side
of the split-vat.

End calibration check.
When you have finished steps
5 through 7 for the vat (in-
cluding both sides of a split-
vat), press the on/off button to
end the calibration check for
the vat.
