You can set one pair of temperature and time
in one step. (When the unit attains to the set
temperature, the operation continues during
the set time.) To start or stop operation, press
key.
Refer to the section program 4 on the page 2

Step operation B (Time prior control)
You set 2 steps and they are repeated.
You can set one pair of temperature and time
in one step. (Heat up time and cool down tim
e
are included in the set time (t).) To start or
stop operation, press
key.
Refer to the section program 5 on the page 2

Repetition times
You can set operating times of program.
Set and run times are shown as below.
• Only one time operation (Not repeated)
Repetition time --> 1
• 2 ~ 99 times operation
Repetition time --> 2 ~ 99
• Repeating until key is pressed.
Repetition time --> 0
Steps
Temperature prior control
Time prior control
Step means a process of program. Operation is
started from the step 1. After the unit attains to the s
e
temperature and controls during the set time, the
operation goes to the next step.
In the temperature prior control, the temperature is ke
p
for the set time after the unit attains to the set
temperature.
In the time prior control, when the set time has elapse
d
the operation goes to the next step. Heat up time and
cool down time are included in the set time.

You can set 8 steps. One pair of time and
temperature can be set in one step.
Steps are combined each other, and they can be
repeated. To start or stop operation, press
key.
Refer to the section program 7 on the page 38.

• Lower limit temperature alarm (Under shooting)
Set upper limit temperature alarm. Press

• Auto tuning
This unit is controlled by a built-in
microprocessor based on PID control. The
most suitable PID constant is set before
shipment. If the temperature accuracy
becomes low, PID constant is tuned
automatically.
To set auto-tuning, press
key to switch to the adjustment
mode. And then press

the upper limit value. In this function the
detection starts after the measured temperature
attains to the upper limit alarm range.
The set value (SV indication) blinks.
• Lower limit temperature alarm (Under shootin

detection starts after the measured temperature
attains to the lower limit alarm range.
The set value (SV indication) blinks.
• Power failure alarm
Detects power failure while controlling, and the
alarm occurs when power recovers.
The operation depends on settings for recoverin
