การตั้งค่า

1. การแกะกล่อง

Carefully remove the hotplate from its packaging. Inspect the unit for any signs of damage incurred during transit. Retain the original packaging for future transport or storage.

2 การวาง

Place the MR HEI-Tec on a stable, level, non-flammable, and heat-resistant workbench. Ensure there is adequate clearance around the unit for ventilation and safe operation.

3. การเชื่อมต่อไฟฟ้า

Connect the power cord to the power input socket on the rear of the hotplate (refer to Figure 2). Plug the other end into a grounded 115V AC power outlet. Ensure the power supply matches the unit's requirements.

4. PT1000 Temperature Sensor Connection (Optional)

If using the optional PT1000 temperature sensor for external temperature control, insert the sensor's plug into the designated PT1000 port on the rear of the unit (refer to Figure 2). Position the sensor within your sample solution for accurate temperature measurement.

คำแนะนำการใช้งาน

1. การเปิด/ปิดเครื่อง

To power on the unit, press the main power switch located on the side or rear of the device. The digital display will illuminate.

2. Setting Stirring Speed

1. Place a suitable stirring bar into your vessel containing the liquid to be stirred.
2. Place the vessel on the center of the hotplate surface.
3. Press the stirring button (often indicated by a propeller icon) to activate the stirring function. The button will illuminate.
4. Rotate the control knob to adjust the stirring speed. The digital display will show the current RPM. The speed can be set from 100 to 1,400 rpm.
5. To stop stirring, press the stirring button again.

3. Setting Heating Temperature

1. Press the heating button (often indicated by a wave or heat icon) to activate the heating function. The button will illuminate.
2. Rotate the control knob to set the desired temperature. The digital display will show the set temperature, which can be adjusted up to 300°C.
3. The hotplate will begin to heat, and the display will show the actual surface temperature or the temperature measured by the PT1000 sensor if connected.
4. To stop heating, press the heating button again. The heating indicator light will turn off.

4. Using the PT1000 Temperature Sensor (External Control)

When the PT1000 sensor is connected, the hotplate will use its readings for precise temperature control of your sample. The independent safety circuit will monitor the hotplate surface temperature to prevent overheating, switching off heating if it exceeds 25°C above the set point.

5. คุณสมบัติด้านความปลอดภัย

• Independent Safety Circuit: Automatically cuts off heating if the hotplate surface temperature exceeds the set temperature by 25°C, protecting your sample and the device.
• Separate Heating On/Off: The dedicated heating button prevents accidental heating. Its illumination provides clear visual confirmation when heating is active.

การซ่อมบำรุง

1. การทำความสะอาด

Always disconnect the unit from the power supply before cleaning. Allow the hotplate surface to cool completely. Wipe the exterior surfaces with a soft, damp cloth and a mild detergent. Do not use abrasive cleaners or solvents. Ensure no liquids enter the device.

2. การจัดเก็บ

When not in use, store the hotplate in a clean, dry environment, away from direct sunlight and extreme temperatures. If storing for extended periods, it is recommended to use the original packaging.

3. การดูแลทั่วไป

Regularly inspect the power cord and plug for any signs of damage. Ensure the hotplate surface is free from scratches or damage that could affect performance. Do not attempt to repair the unit yourself; contact qualified service personnel.
