Operation Method
Preparation for Operation
Set the shelf:
Use the shelf of attached accessory. Permissible load of the shelf is
approximately 15kg. Do not put too much sample.
Set sample:
Set samples with space between each of them. Make room more than
30% of the shelf in order to keep accuracy of temperature.
Connect the power code:
Connect the power code to a proper receptacle securely.
Read the following without fail before using the vacuum pump
Use a vacuum pump with air volume displacement of approximately 50 liters/min.
The vacuum pump shall be connected to the main unit before starting operation.
Check no vacuum air leakage exists before turning on the power of this unit.
Make bath to vacuum state:
Return bath to
atmospheric pressure:
Close the purging valve to vacuum the bath. Turn on the power switch
of vacuum pump after opening the vacuum valve.
After the power switch of vacuum pump is turned on, the scale at the
front of the unit gradually slants to the left until it reaches to
approximately 100 Pa.
Vacuuming time is around seven minutes for ADP21 and around ten
minutes for ADP31under an ambient temperature.
Close the vacuum valve and open the purge valve.
Turn off the power switch of the vacuum pump after returning the inlet side of pump to
atmospheric pressure. If not, oil inside the pump may flow back to the bath.
When using powder-type sample, open the purging valve gradually to avoid powder flying.

temperature measurement circuit, CPU, sensor and
output circuit. Overheating prevention temperature
can be set using the operation panel.
The unit stops operation when the device is
activated. The unit starts operation again when the
POWER switch is pressed again (manual reset).

Operation Method
Setting of Overheating Prevention Device
The unit has the overheating prevention device (manual reset) that consists of independent temperature
measurement circuit, CPU, sensor and output circuit (it shares power source, display, and key input with
the controller) in addition to the automatic overheating prevention function (auto reset) in the controller.
Setting range/function
The unit has failsafe functions against overheating. One of them is built in the controller and previously
set at factory shipment so to be automatically activated when the temperature exceeds the setting
temperature of temperature controller by 12℃, where the heater repeats on and off.
The other is united with the controller, which can be set by operating the keys on the controller.
The setting range of latter is from 0℃ to 1300℃.
In case the temperature in furnace exceeds the setting temperature of controller to reach to that of
overheating prevention device, the circuit is shut off and "Er19" is displayed with blinking on the screen of
controller with buzzer sound.
If the device is once activated,"Er19"continues to be displayed until the power is newly turned on.
Temperature setting procedure
1. Turn on the power (turn on the breaker in front)
• The default value is displayed for about four seconds after
turning on the power. The screen then displays the initial
setting. The current temperature in furnace, operation
mode character and setting temperature of overheating
prevention device are displayed on respective screens.
2. Set the temperature for overheating prevention
① Press the SUBMENU key.
② Press the " ▼ ▲ " several times to select the setting
character of overheating prevention temperature "OH".
③ Press the ENTER key. The current setting temperature is
displayed with blinking on the setting temperature screen.
Note: To prevent improper operation, set the value 12℃ or more
over the setting temperature of controller.
④ Select the value using the " ▼ ▲ "and then press the
ENTER key. This completes the setting.
Notes:
• The standard setting temperature of device is "the maximum setting temperature of unit plus
12℃" or "setting temperature plus 12℃".
• The setting range of overheating prevention device is from 0℃ to 1300℃. Improper setting
of temperature may cause inoperative of unit, malfunction of device, e.g. it is activated during
increasing in temperature in furnace, or unexpected accidents such as fire disaster.
To prevent such matters, set a proper value.
• The temperature is set at 252℃ for the ADP21 and ADP31 at factory shipment。
• In some case, the overheating prevention device is possible to be activated by mistake when
its yield temperature is set to around room temperature.
• The purpose of overheating prevention device is to protect the unit from overheating. It does
not intend to protect the samples, or to protect them from the accident caused by the use of
explosive or inflammability.

Other Functions
Use calibration offset function
Calibration offset is a function which corrects the difference between the temperature in furnace and
that of controller (sensor temperature) if arises. The function parallel corrects the difference either to
the plus or minus side within the whole temperature range of unit. The function can be set or
cancelled by the SUBMENU key.
Corrected temp. to plus side
Current temperature
Corrected temp. to minus side
①
Start operation with the target setting temperature.
Check the
temperature in furnace (temperature of sample) with a thermograph after
it is stabilized.
② Check the difference between the setting temperature and that in furnace
(temperature of sample).
③ Press the SUBMENU key. Select the character "cAL", which indicates
the calibration offset, using the "▲▼", and then press the ENTER key.
④ Input the difference using the "▲▼" and then press the ENTER key.
This completes the setting.
The setting range of offset correction temperature is +99℃ to plus side and
-99℃ to minus side respectively.
When it is set to the minus side, the temperature on the measurement
temperature display screen falls by the setting temperature, while the
temperature on furnace rises.
When it is set to the minus side, the temperature on the measurement
temperature display screen rises by the setting temperature, while the
temperature on furnace falls.
The unit has two-point correction function, which performs offset between
low-temperature zone and high-temperature zone. Please consult our local
