5. Operating Instructions
Understand the various functions of your BOMATA Kitchen Scale:
- Basic Weighing: Place the scale on a flat, stable surface. Press 'ON/OFF' to turn it on. Once '0.0g' is displayed, place the item to be weighed on the center of the platform. The weight will be displayed.
- Unit Conversion: Press the 'UNIT' button to cycle through available units: grams (g), ounces (oz), pounds (lb), milliliters (ml) for water, and milliliters (ml) for milk.
- Tare Function: To weigh items in a container, place the empty container on the platform and press the 'TARE' button. The display will reset to '0.0g'. Add your ingredients to the container, and only the weight of the ingredients will be displayed.
- HOLD Function: If weighing a large item that obscures the display, press the 'HOLD' button before placing the item. The display will lock the weight once stable, allowing you to remove the item and read the measurement.
- Percentage Function (%): This function is useful for baking recipes that use percentages (e.g., baker's percentage).
- Place your first ingredient (e.g., flour) on the scale.
- Press the '%' button. The display will show '100%', setting this ingredient as your 100% benchmark.
- Press 'TARE' to reset the display to '0%'.
- Add subsequent ingredients. The scale will display their weight as a percentage of your benchmark ingredient.
- Counting Function (PCS): For counting small, uniform items.
- With the scale on, press the 'PCS' button.
- Select a sample quantity (e.g., 25, 50, 75, 100) by pressing 'UNIT'.
- Place the corresponding number of sample items on the platform and press 'PCS' again. The scale is now calibrated for counting.
- Add more items, and the scale will display the total count.
- Backlight Control: Press the 'LIGHT' button to turn the LCD backlight on or off.
- Auto-Off Function: The scale is set to automatically turn off after a period of inactivity to save power. This feature can typically be disabled by referring to the detailed instructions in the included paper manual for specific button sequences.

6. Maintenance
To ensure the longevity and accuracy of your BOMATA Kitchen Scale, follow these maintenance guidelines:
- Cleaning: The stainless steel weighing pan is durable and easy to clean. Wipe the scale with a soft, damp cloth. Do not immerse the scale in water or use abrasive cleaners, as this can damage the internal components.
- Storage: Store the scale in a cool, dry place away from extreme temperatures and humidity. Avoid placing heavy objects on the scale when not in use.
- Battery Care: If using AAA batteries, remove them if the scale will not be used for an extended period to prevent leakage. For the rechargeable battery, ensure it is charged periodically to maintain its health.
- Handle with Care: Avoid dropping or subjecting the scale to sudden shocks, as this can affect its precision.
