This also switches the display to the set temperature function. To return to dis-
playing the temperature press the “EXIT” button. If the cut-out is still in the

fore the cut-out can be reset.

Temperature Set-point
The temperature set-point can be set to any value within the range and with the
resolution as given in the specifications. Be careful not to exceed the safe upper
temperature limit of any device inserted into the well. The safety cut-out should
be properly adjusted to help prevent this occurrence.
Setting the temperature involves two steps: (1) select the set-point memory and
(2) adjust the set-point value.

Programmable Set-points
The controller stores 8 set-point temperatures in memory. The set-points can be
quickly recalled to conveniently set the calibrator to a previously programmed
temperature set-point. To set the temperature one must first select the set-point
memory. This function is accessed from the temperature display function by
pressing “SET”. The number of the set-point memory currently being used is
shown at the left on the display followed by the current set-point value.
