This method can be used for calibrating the top plate surface.
To set a Single Point Calibration (SPC) adjustment:
a. Turn the heat knob clockwise until the display reaches the desired heat setting,
and let the unit stabilize to the user input temperature. The heater temperature
has stabilized when the temperature display is no longer blinking and the unit
will beep five times.
b. Wait ten minutes for the surface temperature to stabilize. Measure the top plate
with a traceable surface temperature measuring device.
c. Press and hold the Last Temperature button. The display will start to scroll
through the available SPC options (“UP”, “dn”, “SEt” and “dEL”) as long as
the Last Temperature button is held down. Once you select “UP” or “dn” mode
and release the Last Temperature button the unit will beep two times and the
display will begin to blink quickly. This lets you know you are programming in
SPC mode.
NOTE:
There is a thirty second time out (Last Temperature button must be pressed at
least once in thirty seconds, or unit will exit SPC mode).
Do not touch the heat knob
while in SPC mode.
If the heat knob is adjusted during this procedure you will exit
SPC mode.
d. Once the desired option is displayed, release the Last Temperature button.
Please see the explanation below for each option.
e. Selecting the “SEt” option saves the Single Point Calibration adjustment for that
temperature set point and allows you to exit this SPC mode (see Section c).
When the “Set” option is selected “SEt” will be displayed. To save the current
SPC point and exit the SPC programming mode, release the Last Temperature
button when “SEt” is on the display. The display will now show your set point
temperature with a decimal point for that setting.
f. Select the “UP” option if your externally measured temperature of the top plate
is
higher
than the set point on the display. When the “UP” option is selected
the current SPC adjusted temperature is displayed and blinking quickly.
To
increase the SPC, press and release the Last Temperature button multiple
times (do not touch heat knob)
until the display reads the value you recorded
