This will also switch the display to the set temperature function. To return to
displaying the temperature press the “EXIT” button. If the cut-out is still in the
over-temperature fault condition the display will continue to flash “cut-out”. The
bath temperature must drop a few degrees below the cut-out set-point before the
cut-out can be reset.
9.3 Temperature Set-point
The bath temperature can be set to any value within the range and with
resolution as given in the specifications. The temperature range of the particular
fluid used in the bath must be known by the operator and the bath should only be
operated well below the upper temperature limit of the liquid. In addition, the cut-
out temperature should also be set below the upper limit of the fluid.
Setting the bath temperature involves three steps: (1) select the set-point
memory, (2) adjust the set-point value, and (3) adjust the vernier if desired.
9.3.1 Programmable Set-points
The controller stores 8 set-point temperatures in memory. The set-points can be
quickly recalled to conveniently set the bath to a previously programmed
temperature set-point.
To set the bath 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.
