Operation near or below ambient
temperatures. A water supply or external
chiller may be used to maintain the
temperature
of the bath for cooler
temperature. Hose-barb connections for
water or refrigerated coolant are located at
the back of the bath. There are two
connections: inlet and outlet. The hose
connections can be secured with copper
wire or pull ties to prevent the tubing from
disengaging from the connection.

proceeding with any testing.
Temperature Calibration. This routine allows
the digital temperature controller to be
calibrated to a certified thermometer. In the
calibration mode, the display will always give
2 decimal places.
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
