• Using the Tare Function:
  • To weigh multiple ingredients in one container or to exclude the weight of the container, place the container on the scale and press the tare button. This will reset the scale to zero, allowing you to add and weigh the first ingredient.
  • Add your ingredient to the container. The display will show only the weight of the ingredient.
  • For additional ingredients, press the tare button again and repeat the process.
• Reading the Measurement:
  • Once the item is placed on the scale, wait a moment for the scale to stabilize. The final weight will be displayed on the LCD screen.
• Turning Off the Scale:
  • The scale will automatically turn off after 30 seconds of inactivity to conserve battery life.
  • You can also manually turn off the scale by pressing the power button.
• Cleaning and Storage:
  • Wipe the scale with a clean, dry cloth after use. Avoid using harsh chemicals or immersing it in water.
  • Store the scale in a dry place when not in use to protect its sensitivity and accuracy.
• Battery Replacement:
  • When the LCD display dims or the scale becomes unresponsive, it may be time to replace the batteries. Open the battery compartment and replace the old batteries with new AAA batteries.

Safety Precautions

• Handle the scale with care as it is a precision instrument. Dropping or jarring the scale can damage its internal mechanisms.
• Do not exceed the maximum weight capacity of 3 kilograms. Overloading can permanently damage the sensors.
• Always place the scale on a stable, flat surface while using it. Uneven surfaces can lead to inaccurate measurements.
• Do not expose the scale to water or any liquid. This can damage the electronic components. If spillage occurs, wipe it off immediately with a dry cloth.
• Avoid using harsh chemicals, solvents, or detergents to clean the scale. A mild, damp cloth is sufficient for cleaning the surface.
• Keep the scale and its batteries out of reach of children. Small parts and batteries can pose a choking hazard.
• Do not store or use the scale in extreme hot or cold temperatures, as it can affect the scale’s accuracy and electronics.
• Do not attempt to disassemble or repair the scale yourself. Unauthorized modifications could result in a safety hazard and void the warranty.
• Avoid using the scale near strong electromagnetic fields, as they may interfere with its accuracy.
• When weighing sharp or pointed objects, be cautious as these can scratch the weighing surface or injure the user.
• Use the scale only for its intended purpose of weighing items within its capacity. It is not designed for industrial or heavy-duty usage.

Battery Safety

• Insert batteries according to the correct polarity. Incorrect installation can cause battery leakage or rupture.
• Remove batteries if the scale will not be used for an extended period to prevent damage from battery leakage.

Troubleshooting

• Scale Does Not Turn On:
• • Ensure that the batteries are properly installed with the correct polarity.
  • Check if the batteries are depleted and replace them if necessary.

• • Gently clean the buttons with a soft, damp cloth to ensure that there is no residue causing them to stick.
  • Avoid pressing the buttons with excessive force.
• Fluctuating Measurements:
• • Ensure no drafts or temperature changes are affecting the scale.
  • Wait a few seconds for the scale to stabilize before taking a reading.
• Scale Turns Off Unexpectedly:
• • The scale may have an auto-off feature to conserve battery life. Refer to the user manual to determine the expected duration before auto-off activates.
  • If the scale turns off too quickly, there may be an issue with the batteries or internal electronics.
• Unit of Measure Won’t Change:
• • Press the ‘MODE’ button to cycle through the units. If the button doesn’t respond, try resetting the scale.
