Preparations
(1) Install hose connectors on the [VACUUM]
and [LEAK] ports on the back of the
instrument.
•Push them in until they click into place.
•To the [VACUUM] hose port, connect the
hose from a pump or other equipment for
evacuating the bell jar.
•To the [LEAK] hose port, connect the hose
from an inert gas cylinder or other source,
depending on the intended objectives.
< CAUTION >
* Evacuation, releasing the vacuum to the
atmosphere, injecting inert gas, and other
such operations are not possible without
installing the hose connectors.
* If using a cylinder to supply inert gases, use
a pressure regulator valve for safety.
* To disconnect hose connectors after use,
pull them out while holding the [VACUUM]
port (or [LEAK] port). Beware that doing so
can cause the hose connector to pop out
with considerable force.
(2) Apply a thin coating of silicone grease provided with the O-ring seal (See page 8.).
< CAUTION >
* If the silicone grease wears off and a vacuum is maintained for a long time, the bell jar can
become stuck to the O-ring, making it difficult to remove.

(3) Place the sample on the heating table and cover it with the bell jar.
(4) Set the selector valve to [VACUUM] and use a vacuum pump or other means to evacuate the
bell jar.
•When releasing the vacuum to the atmosphere or injecting inert gas after using the oven,
briefly set the selector valve to [CLOSE] before setting it to [LEAK].
< CAUTION >
* Evaluating the bell jar with the heating table already hot could cause sudden vigorous boiling
or other phenomena with certain samples. Take extra care, as this can be very dangerous.
< Useful Advice >
No power supply is required to operate the selector valve. Therefore, some operations, such
as temporary storage of samples under reduced pressure or purging with inert gas,
described in (1) to (4) above, can be performed without power being supplied.
(5) Check that the POWER switch is OFF. Then
connect the power plug to a 100 V AC
grounded 3-pin power outlet.
If there is no grounded 3-pin power outlet,
use the outlet adaptor provided to connect to
a 2-pin power outlet. In this case, be sure to
connect the ground wire to a ground
terminal.

Operation
The temperature setting range for this product is 40 °C to 200 °C. Operate the instrument within this
range.
(1) After switching the power ON, the startup screen is displayed for about 4 seconds. Then
the display changes to the operating mode screen and starts controlling the temperature to
the set temperature (set to 40 °C when shipped).
•The operating mode screen shows the current temperature of the heating table in the [PV]
area and the set temperature in the [SV] area.
(2) Change the temperature setting as desired by pressing the up or down button. After a few
seconds, the instrument registers the new temperature setting and begins controlling the
temperature accordingly.
•Holding the button down causes the value to increase or decrease more rapidly.
After setting the temperature, confirm that the [OUT1] lamp is illuminated (red) and the current
temperature increases.

(3) Specify auto-tuning and over-temperature prevention settings. (This may be omitted.)
•If auto-tuning is not specified, then factory parameter settings (40 °C temperature setting) are
applied. Auto-tuning is recommended even if a temperature setting of 40 °C is desired, due to
differences in the ambient temperature and other factors. (See page 16.)
•Change the setting for the over-temperature prevention function if necessary.
(See page 17.)
(4) When finished using the instrument, switch OFF the power via the operating mode screen.
< CAUTION >
* If the instrument has been operated at a high temperature for a long period, reset the
temperature to 40 °C and confirm that the current temperature has decreased to near 40 °C
before switching OFF the power. Switching the power OFF when the temperature is still high
also stops the cooling fan that discharges heat from inside the instrument housing, possibly
resulting in instrument failure.
< Useful Advice >
The power switch operation and the vacuum operation are independent of each other. (The
power switch is linked to the temperature controller and cooling fan.) Therefore, the vacuum
level can be maintained even without power being supplied.
Setting values (auto-tuning results and temperature setting values) are retained even if the
power is switched OFF.

16
Auto-Tuning
This product is equipped with an auto-tuning function. Using the auto-tuning function provides
more accurate temperature control in response to the ambient temperature and other conditions.
< Auto-Tuning Procedure >
Pressing the [FUNC] button one time immediately starts the auto-tuning function.
During auto-tuning, the screen alternately displays the operating mode and auto-tuning screens.
When the process is complete, only the operating mode screen is displayed, as normal.
•During auto-tuning, each press of the [FUNC] button switches the function ON or OFF.
< CAUTION >
* In some cases, the current temperature can fluctuate near the set temperature during
auto-tuning. This is due to the temperature control process of auto-turning and does not
indicate an abnormality or malfunction.
* If auto-tuning is not performed after the temperature setting has been changed, temperature is
controlled based on the previous auto-tuning parameters. Since the temperature or other
conditions may have changed since the previous time, perform auto-tuning again if
high-accuracy temperature control is desired.
* If you want to avoid heating the sample above the set temperature, preheat the heating
table until the temperature stabilizes (several minutes) before starting use. Note that
placing the sample in the bell jar after the temperature stabilizes will change the control
conditions, which might affect temperature control accuracy.

Over-Temperature Prevention Safety Interlock
This product is equipped with an over-temperature prevention function. If the current temperature
exceeds the over-temperature prevention temperature setting, the [EV] lamp on the temperature
controller display illuminates and power to the heater is shut OFF. *1
There are two over-temperature prevention modes, A and B, as indicated below.

Over-Temperature
Prevention Mode A
Set temperature + user-specified
temperature margin *2 [EV1] lamp illuminates.
Over-Temperature
Prevention Mode B 210 °C (fixed) [EV2] lamp illuminates.
* 1 Power to the heater is shut OFF, but power is still supplied to the instrument.
* 2 Set to 10 °C when shipped from the factory.
< How to Set Over-Temperature Prevention Mode A >
(1) Pressing the [MODE] button once displays the over-temperature prevention setting screen.
•On the over-temperature prevention setting screen, the over-temperature prevention
setting is displayed in the [SV] area.
(2) Change the over-temperature prevention setting as desired by pressing the up or down
button. Pressing the [MODE] button once confirms the setting and displays the operating
mode screen.
In this case, the temperature is calculated as the set temperature (100 °C) plus the
user-specified temperature margin (5 °C), so over-temperature prevention mode A is
activated when the current temperature is 105 °C or higher.

< Precautions Regarding the Over-Temperature Prevention Safety Interlock >
* This product employs a PID controller to control temperature. PID control can cause the
current temperature to fluctuate near the set temperature even after the target temperature
has been reached. Therefore, it may trigger the over-temperature prevention function if the
over-temperature prevention temperature setting is too low.
* During auto-tuning, the instrument makes the current temperature fluctuate near the set
temperature to decide an optimal PID constant, thus ensuring proper temperature
control. Therefore, it may trigger the over-temperature prevention function if the
over-temperature prevention temperature setting is too low.
* During temperature control, sudden changes in room temperature or actions such as
removing the bell jar or increasing/decreasing the sample quantity in the bell jar may trigger
the over-temperature prevention function.
* If auto-tuning has not been performed, temperature control may become unstable, and the
over-temperature prevention function may be activated.
< Resetting the Over-Temperature Prevention Safety Interlock >
•To resume normal temperature control after the over-temperature prevention function is
activated, the over-temperature prevention function must be reset.
To reset the over-temperature prevention function, switch the power OFF and then switch it
back ON.
If the reason the over-temperature prevention function was activated is not known, please
contact a Sibata representative for service.
