5. Maagizo ya Uendeshaji

The PC-620D features intuitive controls for both heating and stirring functions.

5.1. Kazi ya Kupokanzwa

  1. Washa: Turn the temperature control knob from 'OFF' to the desired temperature setting. The unit will power on, and the temperature LED readout will illuminate.
  2. Weka Joto: Adjust the temperature control knob to set the desired temperature. The temperature can be set from ambient +5°C up to 550°C in 5-degree increments. The dual LED display will show the set temperature.
  3. Ufuatiliaji wa halijoto: The hot plate will begin heating. The external temperature controller, if connected, helps ensure regulation to ±2°C.
  4. Hot Top Indicator: A 'HOT TOP' light will illuminate when the surface temperature is above 60°C, even if the power is off. This is a safety feature.

5.2. Stirring Function

  1. Place Stir Bar: Carefully place a stir bar (sold separately) into the vessel containing the liquid to be stirred.
  2. Washa: Turn the stirring speed control knob from 'OFF' to the desired speed setting. The unit will power on, and the speed LED readout will illuminate.
  3. Weka Kasi: Adjust the stirring speed control knob to set the desired RPM. The speed range is 60 to 1,150 rpm. Speed settability varies: 5 rpm at 60-100 rpm; 10 rpm at 100-200 rpm; 20 rpm at 200-400 rpm; 50 rpm at 400-1,150 rpm.
  4. Anza polepole: The stirring control slowly increases speed for improved safety and enhanced coupling with the stir bar, especially for viscous solutions.

6. Matengenezo

Proper maintenance ensures the longevity and optimal performance of your hot plate.

  • Kusafisha: Always disconnect the unit from power and allow it to cool completely before cleaning. Wipe the Pyroceram top plate with a damp cloth and mild detergent. For stubborn stains, a non-abrasive cleaner suitable for glass-ceramic surfaces can be used. Avoid abrasive pads or harsh chemicals.
  • Kumwagika: Immediately clean any spills on the hot plate surface to prevent residue buildup or damage.
  • Huduma ya Jumla: Keep the unit free from dust and debris. Do not immerse the unit in water. Inspect the power cord for any signs of damage regularly.

7. Utatuzi wa shida

If you encounter issues with your hot plate, refer to the following common troubleshooting steps:

  • Unit Does Not Power On:
    • Check if the power cord is securely plugged into a live electrical outlet.
    • Ensure the temperature or stirring speed knob is turned from the 'OFF' position.
    • Verify the circuit breaker or fuse for the outlet has not tripped.
  • Hot Plate Not Heating:
    • Confirm the temperature setting is above ambient temperature.
    • Ensure the external temperature controller is properly connected and functioning if in use.
  • Stirring Not Functioning:
    • Ensure the stirring speed knob is turned from the 'OFF' position and set to a desired RPM.
    • Verify that a suitable stir bar is placed correctly in the vessel and is not stuck.
    • Check if the liquid viscosity is too high for the selected speed or stir bar.
  • Usomaji wa Halijoto Usio Sahihi:
    • Ensure the external temperature controller probe is correctly positioned within the solution.
    • Verify the probe is clean and undamaged.

If problems persist after attempting these steps, contact Corning customer support for further assistance.
