IMPORTANT
NOTE:
The
digital
temperature controller for the unit comes
pre-programmed from the Koehler factory.
Please do NOT attempt to re-program the
digital temperature controller as this will
void the product warranty. If assistance is
required, please do not hesitate to contact
the Koehler technical service department.
Setting the Temperature
. Set the desired
operating temperature by adjusting the set
point with the up and down keys. The set point
will be displayed in the lower green Set Point
LED display and the actual temperature will be
displayed in the upper red Process LED
display. Please allow the instrument to fully
equilibrate before proceeding with any testing.
Temperature Calibration.
This routine allows the
digital temperature controller to be calibrated
to a certified thermometer.
a. Use a certified calibrated measuring
device to
acquire the
temperature.
Calculate the difference between the
measuring device and the Process value
displayed on the controller.
b. Press the program key two times until
PCt
is displayed in the lower green LED
display. Press the DOWN key. CAL will
display on the lower green display. If there
is a value observed in the upper red LED
display, add it to the calculated difference
obtained in the previous step. This is the
offset value.
c. Press the Program Key. The lower green
display will flash. Use the up or down keys
to adjust to the new calibration offset
value on the upper red display calculated
in the previous step. When the value has
been
entered,
the
controller
will
automatically store the value. The lower
green display will stop flashing. If further
adjustments are necessary, press the
Program Key again. Resume regular
operations by pressing the Exit / Function
key two times. Verify if the new calibration
is correct by observing the upper red
display and comparing the value with the
calibrated reference device.
Auto Tune.
This routine allows the digital
temperature control to learn the heating
parameters needed for any particular set point
temperature. This operation should be done
when installing a new unit, after replacing or
changing the bath medium type, or utilizing a
different temperature set point 20% different
from
the
previously
used
set
point
temperature.
