TEMPERATURE CALIBRATION
To compensate for lead wire resistance, it may be neces-
sary to make an adjustment to the displayed temperature
to correct it to the temperature measured at the thermis-
tor 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 tempera-
ture 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.
