After uniform thin films coated, the liquid solution is necessary to be solidified.
At this moment, hot plate is used to solidify the solution.
The temperature is accurately controlled by a temperature controller that uses digital
PID auto-tuning function, setting and real temperature can be simultaneously con-
firmed.
Temperature controller built-in timer function.
Ceramic coated top plate has rapid thermal conductivity and very uniformly maintain
the surface temperature.
Stirring speed is maintained constant speed by feedback control.
What is the hot plate and features?

A. After all parameters are set, button is pressed for more than 2 sec. to escape the parameter set-
ting state. At this moment, the current and setting temperature are displayed at measurement unit
display (PV) and setting unit display (SV) respectively and the control is started.
B. If pressing button for more than 2 sec., the controller runs optimum control to operate automati-
cally the most proper PID integer to the thermal properties of the actuator controller.
C. If there is no any button operation for more than about 60 sec., returning to the initial state. At
this moment, the previous parameter value is stored, not set parameter value.

1. ① After designating external sensor operation by # 16 button, insert sensor connector at # 17.
(When using external sensor)
② Designate internal sensor operation. (When using internal sensor)
2. After connecting cable to # 15, turn on the power switch of # 14.
3. If pressing # 8 button for about 2 sec., the parameter of temperature setting is displayed. The expec-
tative temperature is defined by pressing # 9 and 10 buttons.
4. If pressing # 8 button for a few sec. after setting the temperature, the temperature controller is oper-
ated. (initial state)

1. The parameter of temperature setting is displayed with pressing # 8 button for a few sec.. If press-
ing # 8 button again, “tlm” is displayed. The expectative time is defined by pressing # 9 and 10 but-
tons. Minimum 1 min. (0001) ~ maximum 99 hr. 59 min. (9959)
2. If pressing # 8 button for a few sec. after timer setting, returning to initial state.
3. When operating the timer, press # 10 button for about 2 sec.. At this moment, the lamp of # 6 is
blinked. If the timer is not set, not operating.
4. If pressing # 10 button for about 2 sec. while the timer is operating, operation is stopped.
5. If pressing # 9 button for about 2 sec. while the timer is operating, remaining time is displayed. At
this moment, if pressing # 9 button for a few sec. again, the setting temperature is displayed.
6. When the timer is over, “tENd” is displayed. If returning to initial state, press # 10 button for a few
sec.

1. Because this PID Temp. Controller have already calculated PID values by experiment, it can be
used without additional auto-tuning. If the temperature difference occurs a lot, auto-tuning is rec-
ommended.
2. Auto-tuning is started by pressing # 11 button and the lamp of # 5 is blinked.
3. Although there are some temperature errors during auto-tuning, the exact temperature is activated
after auto-tuning is over.
4. When using the thermostat, the temperature is firstly increased more than the set temperature but
returned to normal state after a while. (Overshoot phenomenon)

The expectant speed (# 12 display) is defined by rotating # 13 volume.
1. The speed can be controlled from 100 to 1500 rpm by adjusting volume. (The speed is in-
creased by clockwise rotating # 13 volume or decreased by anticlockwise rotating # 13 vol-
ume in 10 rpm step.)
2. If anticlockwise rotating # 13 volume fully, the operation is stopped.
3. If rpm is set by rotating # 13 volume, the speed is reached to the setting rpm within a few
sec.. The speed is maintained by the operation from the arrival time.
4. If the motor is not immediately rotated due to the influence of the load at first operation, the
output should be quickly increased up to above 10 rpm to rotate the motor within 3 sec..
