Cancel Button: The Cancel button is used to cancel a program step while writing or editing a
program or to cancel any setting if made in error.
Run Button: The Run button is used to start running a program in memory.
Enter Button: The Enter button is used to enter a value setting into the unit in manual operation
or in a program.
X. SIMPLE OPERATION
The HP/HS60 Series units are fully programmable. They have the ability to write and store in
memory ten programs of as many as ten steps each for instant recall and later use. Also, these
units can be used to set a single temperature, temperature ramp, stirring speed and timer function
without going into the memory. The memory is used for complex routines where all the
parameters of the sample can be changed automatically to other values without user attention.
TEMPERATURE
The user may enter either a target probe temperature or a target plate temperature. Only one
target temperature is allowed at one time. Setting a target probe temperature will erase any
target plate temperature previously set and vice versa. Target temperatures may be set anywhere
in the range from ambient to 450
Ε
C or 842
º
F in ceramic topped units, or from ambient to 400
º
C
or 752
º
F in aluminum topped units. The unit comes with the display reading in degrees C. To
change to
º
F depress and hold the HEATER OFF button until the display changes. To change
back to
º
C repeat the process.
Setting Solution Temperature: When setting a solution temperature, plug the probe into the jack
on the rear of the unit and place it into the solution. With the probe plugged in, the unit will only
set and control the solution temperature as controlled by the probe. With the probe unplugged,
only the plate surface temperature is sensed and controlled by the unit. Next, touch the
HEATER button and use the UP, DOWN. RIGHT, LEFT arrows to enter the value of the
temperature wanted. Then press ENTER. The unit will now turn the heater on and drive the
solution to the target temperature. Note that the temperature display will toggle between the
target and the actual temperatures. When the target temperature is reached, the display will still
toggle but the numerical value will remain the same.

CAUTION: Be certain the temperature probe is in the solution when a solution
temperature target has been entered. Failure to do so could damage your sample because
the hot plate will drive to maximum while seeking a temperature it cannot find.
