timer will now start to count down toward zero. When the timer reaches zero it will sound the
audible alarm. To stop the alarm press CANCEL.
Setting Auto-Off: The auto-off function is used with the timer. When activated, the unit will
turn off the heater and stirrer when the timer counts down to zero. To set the auto-off function,
press the AUTO-OFF button. The display will illuminate the words
A
AUTO-OFF
@
to the right
of the timer telling the user that the auto-off function is set. To turn off the auto-off function,
touch the AUTO-OFF button again. The words,
A
AUTO-OFF
@
will no longer be illuminated in
the display. Remember that when AUTO-OFF is on, the unit will automatically turn off the
heater and stirrer when the timer counts down to zero.
XI. PROGRAMMABLE OPERATION
The HS60 series have the ability to store ten programs in memory for instant recall and use.
Each program has ten steps maximum where one step is a temperature, stirring speed, ramp
function (if wanted), and time. At the end of each program there is a cycle step that can be
selected to repeat the program up to 98 times. Setting cycles to 99 makes the program repeat
infinitely. These programs are stored in CMOS and cannot be lost by a power failure or by
turning the unit off. However, if power fails during a program run, when power returns, the unit
will have lost its instructions and will be sitting with the same information on the display as
when the unit was first turned on. To stop a program while it is running touch CANCEL.
Some rules for programming:
To erase all programs in memory, depress and hold the EDIT key for about 5 seconds. The
display will be all blank. When the EDIT key is released, after a few seconds or, the
display will return to the normal screen and the programs will be erased. This erases ALL
programs in memory. To change or erase one program the user must go into the program
and remove each step.
The timer can be used in two ways in a program. The timer can be used with a ramp
function or without a ramp function. When the timer is used with a ramp function, the
timer does not start to count down until the target temperature is reached. When the timer
is used without a ramp function, the timer starts to count down as soon as the program
starts. If the user wants a timed event to start after the target temperature is reached, but
13
does not want to wait for a ramped approach to the target temperature to take place, set
the ramp to 450. In almost all cases, this ramp rate is faster than the unit can approach the
target temperature, and it will appear as though no ramp rate is being used, and the timer
will start to count down after the target temperature is reached.
RUNNING A PROGRAM STORED IN MEMORY
1. Press RUN. The display will show PROG 1 at the bottom of the display to the left of the
timer. This is program 1.
2. If program 1 is the choice to be run, next press ENTER. Program 1 will now start to run. If
