4. Preparation for use
13
①Place the heating plate on the microscope stage.
* For inverted microscopes, please be careful not to entangle the plate cable
with objective lens.
②Connect the heating plate to the plate connector of controller.
* When removing, please pull the cable while
pressing the convex part shown in the left figure.
③Connect the AC adapter to the power connector of controller and connect
the power cord.
④When using TEM (temperature logging software), connect the USB cable
which is included in the package to the controller.
⑤If the glass part of the heating plate gets dirty, please clean it up.
⑥Connect the External Temp. Sensor to the Extension Wire and connect the
Extension Wire to the sensor connector of controller.
Installation
Since it is a lock
type connector,
please insert it
deeply.
* Please note that the connector of the Sensor and
Extension Wire have thick pins and thin pins and
the direction of insertion is decided.

Attach the External Temp. Sensor to the glass part of the Heating Plate.
Please be sure to follow the procedure as follows:
Adhesive
tape Attach the cable of the
External Temp. Sensor in
contact with the glass as long
as possible. However, attach it
only to the glass surface.
In order to improve the temp. acquisition property
by pasting it on the glass, it has the shape as shown
in the left.
Image of sensor tip shape
Please attach the flat surface sensor tip to center of glass plate with adhesive tape
for accurate temp. measurement. Remove the remaining air between the tape and
glass to make sure the top is in closed contact with glass.
The flat surface of the External Temp.
Sensor tip is not in close contact with
the glass.

External Temp. Sensor is not
attached to the center of plate. NG External Temp. Sensor is attached over the plate sensor. NG
For measuring temperature
The adhesive tape should not
touch the plate temp. sensor.
The flat surface of the External Temp.

How to use the Mounting Hook
You can use the controller as it is on the flat surface, or use in the following way with the
attached Mounting Hook.
◎When placing the controller on the flat surface
Attach the Mounting Hook as shown above.
Please use it on a flat surface.
◎When using the controller by hanging on the wall
Please prepare a wall hook shown above and
hang the controller.
（Recommended: at intervals of 40 mm, diameter about 5 mm）
Please do not stress the Mounting Hook more than necessary, it may damage the
system. (e.g. prohibited to pull the wall-hanged controller, push the controller from
above while controller is placed on the table.)
Attach the Mounting Hook as shown above.

For accurate temp. control
Before using, be sure to confirm that the serial number stated in the product name
plate on the back of the controller: ○○○○○○ 6 digits matches the cable on the
Heating Plate（near the connector）.
Please do not combine controller and Heating Plate with different serial number. There
is a possibility that temp. may not be controlled correctly.
Please do not let air flow directly over Heating Plate surface. An error may occur in the
Heating Plate surface temp..
Please use a thermometer that can be traced to international or national weighing
standards and check that the temp. indicated by the attached External Temp. Sensor is
correct. Please ensure this confirmation at least once a year. Be sure to use this
thermometer which has a small and thin tip shape. A large thermometer may cause
abnormal heat heating or malfunction of the Heating Plate.
Be sure to check that the temp. at the central part of the Heating plate is near the
setting value with the attached External Temp. Sensor before placing the dish on the
Heating Plate. If there is a phenomenon such as a difference between the Heating
Plate temp and the External Temp. Sensor, refer 6. Procedure for PID Calibration (p.19)
or 7. Shift Calibration (p.20) and do temp. correction.
Be careful not to spill the specimen or the medium in the dish when placing the dish
on the Heating Plate.

5. How to use
①Please turn on the Stand-by Switch and run preliminary operation.
For the preliminary operation, please leave it for about 30 minutes
to 1 hour.
When you press the Stand-by Switch, heating starts. Do not touch the heater part
beyond necessity while heating. It may cause burns.
②Use the UP or DOWN Key to input the setting temp. of Heating
Plate. Refer to 3. Display and parameter (p.10) for the operation.
The Heating Plate temp. will be stable in about 10 minutes after inputting the temp.
setting value.
* Temp. stabilization time varies depending on the plate model.
③Before placing the dish on the Heating Plate, please run temp. check (p.14)
as necessary. Measure the Heating Plate temp. with the attached External
Temp. Sensor and confirm that it matches the setting temp..
As a result of checking the temp., if the Heating Plate temp. does not stabilize in your
environment, please correct the temp.. For temp. correction, refer to 6. PID
Calibration (p.19) or 7. Shift Calibration (p.20).

There is a risk that the sample is not heated
properly.
* When installing a dish on the Harming Plate, please be careful not to spill
the specimen and the medium.
⑤When finishing, turn off the controller by pressing and hold the Stand-by
Switch. Disconnect the plug of Power Cord from power socket after
controller is turned off completely.
⑥If the glass part of the Heating Plate gets dirty, please clean it.

6. PID Calibration
This system adopts PID control for stable temp. control, and the controller is calibrated under
the environment of room temperature 25 ±2℃before shipping. If the temp. of the Heating
Plate is not stable in your environment, the controller can calculate the optimum parameters
according to your environment by carrying out PID calibration so that the Heating Plate temp.
becomes stable.

7. Shift Calibration
The Shift Calibration is for correcting temp. so that the surface temp. of the Heating Plate is
equal to the temp. of the External Temp. Sensor measures.

You can check how much correction was made from the Plate Shift Value in the User Mode.
You can also manually do the Shift Calibration by directly inputting the correction value to
this Shift Value.
Please check the stability of the Heating Plate temp. before carrying out Shift
Calibration. The operating environment is stable within the range of 25 ±2℃, and
the air blowing should not hit the surface of the Heating Plate. It may cause sensor
temp. false detection and the Shift Calibration program may not be finished.
Shift calibration takes at least 30 minutes or more.
