2. Nga korero haumaru

Me whai tonu i ngā mahi ārai haumaru e whai ake nei hei ārai i te whara me te pakaru o te taputapu:

• Mata wera: The top surface can reach high temperatures. Always allow the unit to cool completely before touching or moving. A "HOT TOP" indicator light will illuminate when the surface temperature exceeds 60°C (140°F).
• Haumaru Hiko: Connect the unit only to a properly grounded electrical outlet with the specified voltage (120V/60Hz). Do not operate with a damaged power cord.
• Whakahau: Me whakarite kia pai te hau huri noa i te waahanga kia kore ai e wera rawa.
• Maringi: In case of spills, immediately disconnect the power and clean the unit carefully after it has cooled. Avoid liquid ingress into the internal components.
• Taputapu Tiaki Whaiaro: Always wear appropriate personal protective equipment (e.g., heat-resistant gloves, eye protection) when operating the hot plate.
• Whakamahinga Whakamahinga: Use the hot plate only for its intended laboratory heating and stirring applications. Do not use for heating flammable or explosive materials without proper safety protocols.

5. Mahi

5.1 Mana me nga Tohu

• Tohu POWER: Green light illuminates when the unit is powered on.
• STIR Knob: Controls the stirring speed from 60 to 1150 RPM. Turn clockwise to increase speed.
• STIR RPM Display: Digital LED display shows the current stirring speed in RPM.
• HEAT Knob: Controls the heating temperature from 5°C to 550°C. Turn clockwise to increase temperature.
• TEMPERATURE Display: Digital LED display shows the set temperature in Celsius. It blinks until the set temperature is reached.
• HOT TOP Indicator: Red light illuminates when the top surface temperature exceeds 60°C (140°F), even if the heat function is turned off.

5.2 Stirring Function

1. Place a suitable stir bar into your vessel (e.g., beaker, flask) containing the solution.
2. Place the vessel centrally on the Pyroceram top.
3. Turn the STIR knob clockwise to the desired RPM. The digital display will show the set speed.
4. Adjust the speed as needed for optimal mixing without splashing.
5. To stop stirring, turn the STIR knob counter-clockwise to the "Off" position.

5.3 Mahi Whakawera

1. Place your vessel containing the sample on the Pyroceram top.
2. Turn the HEAT knob clockwise to the desired temperature. The digital display will show the set temperature in 5°C increments.
3. The temperature display will blink until the set temperature is reached, then it will remain steady.
4. Monitor the HOT TOP indicator. It will remain lit as long as the surface temperature is above 60°C, even after the heat is turned off.
5. To turn off heating, turn the HEAT knob counter-clockwise to the "Off" position. Allow the unit to cool down naturally.

6. Tiaki me te Tiaki

• Te horoi: Disconnect the power cord and allow the unit to cool completely before cleaning. Wipe the Pyroceram top and housing with a damp kakahu me te horoi ngawari. Kaua e whakamahi i nga kai horoi me nga whakarewa.
• Maringi: Clean spills immediately to prevent residue buildup. For chemical spills, refer to appropriate safety data sheets for cleaning procedures.
• Rokiroki: Store the hot plate in a clean, dry environment when not in use.
• Tirotiro: Periodically inspect the power cord for any signs of damage.
