TEMPERATURE CALIBRATION
To compensate for lead wire resistance, it may be
necessary to make an adjustment to the displayed
temperature to correct it to the temperature measured at
the thermistor sensor. The calibration feature allows the
displayed temperature to be offset either above or below
the actual sensed temperature. Be sure to use an accurate
temperature meter for making this correction.
1. Press and hold the
HEAT ON
and
HEAT OFF
buttons
while pressing the
UP
or the
DOWN
button until the
correct temperature is displayed. (A period [.] after the
F will indicate the Calibration Mode).
2. Pressing the
UP
or the
DOWN
button will display the
current calibration difference above or below (-) the
measured temperature.
