System Method of Calibration -
Recommended
This method of calibration requires an NIST calibrated
thermometer with a resolution of 0.1°C or better.
1. Select an independent temperature probe to be
placed in the load, along with the unit temperature
probe before continuing with calibration. Select the
load to be calibrated, and place on top of the hot-
plate. Place a stir bar in the mixture if stirring is
desired and available on the unit being calibrated.
Make sure to have probe plugged into the unit and
placed in the load. Also ensure that the OTP adjust-
ment on the front edge of the unit is set high enough
to allow the load to achieve the calibration tempera-
ture.

not turned on yet (displays should be blank, unless
the Hot Top Warning System is indicating a hot sur-
face), enter the Service Menu by pressing and hold-
ing the POWER key. After about 3 seconds a single
beep will be heard and you may remove your finger
from the POWER key. The display will change to
OSP.
3. Rotate the center knob dial one position clockwise
and the display will read CAL. This is the calibration
menu. Press the “Heat” key under the HEAT dis-
play. The display will now read OiL. Rotate the
center knob one position and the display will read
SyS. Press the “Heat” key again to accept, and the

point. The speed may be adjusted by using the
center knob. The adjustable range is 50 – 999,
and also OFF (zero). When the adjustment is
completed, press the “Stir” key under the STIR
display to approve the selection.
6. The HEAT display will now show the tempera-
ture that is currently measured at the probe. If
the display shows “---” then the probe is not
connected to the unit and must be connected
before continuing. The unit will begin heating to
the setpoint. The HEAT and STIR displays will
flash until the temperature is within ±2°C of the
chosen setpoint.
7. Once the temperature is within ±2°C of the set
point, a beep will sound and the “Heat” key
under the HEAT display will begin flashing to let
the user know that the display is ready to be
adjusted using the center knob. Although it may
be desirable to wait longer to allow the tempera-
ture of the unit and fluid to stabilize further.
8. Adjust the HEAT display using the center knob
to make it match the independent probe. When
this is complete, press the “Heat” key under the
HEAT display. The unit will turn OFF automati-
cally. Calibration of the probe system is now
complete.

Errors E11 and E12 are stirring errors. Error Handler will lock out stirring functions if stirring error is detected.
To avoid boil over, the unit will cease heating (the user can restart heating if desired). Pressing the POWER
button or unplugging the unit will clear Error E12. Unplugging the unit will clear Error E11.
Error E21 is a data flash memory error and can be corrected by following the steps below:
• Press any key to clear the error, this re-initializes data flash memory.
• At the ‘SEL’ menu, press the “Heat” or “Stir” key.
• Using the encoder knob, select your unit’s model type (if your unit model number starts with SP,
select ‘ SP’, etc) and press either the “Heat” or “Stir” key.
• Using the encoder knob, select your unit’s top size (either 7 or 10 inch) and press either the “Heat”
or “Stir” key.
• Press the POWER key to exit the special functions menu.
• Note that it may be necessary to recalibrate the unit and/or re-enter custom settings as the unit has
been reset to factory default.
• The unit can now be started normally using the POWER key.
