3. Setup

3.1 Unpacking and Placement

1. Carefully remove the scale from its packaging.
2. Place the scale on a stable, level surface. Use the adjustable feet to ensure the scale is perfectly level, indicated by the level bubble.
3. Avoid placing the scale in environments with excessive vibration, strong airflow (wind/air conditioning), radiation/dust, or strong electromagnetic interference from high-power appliances. These factors can affect measurement accuracy.

3.2 Power Supply

The scale can be powered by either the included AC adapter or 4x AA batteries (not included).

• AC Adapter: Connect the DC 7.5V power adapter to the scale's power input and plug it into a suitable power outlet.
• Batteries: Open the battery compartment on the underside of the scale and insert 4x AA batteries, ensuring correct polarity.

4. Operating Instructions

4.1 Basic Weighing

1. Press the ON/OFF button to turn on the scale. Wait for the display to show "0.0 g".
2. Place the item to be weighed directly onto the center of the stainless steel weighing pan.
3. Read the weight displayed on the LCD screen.
4. Press the ON/OFF button again to turn off the scale.

4.2 Tare Function

The tare function allows you to subtract the weight of a container, so only the weight of the contents is measured.

1. Place an empty container on the weighing pan. The display will show the container's weight.
2. Press the TARE button. The display will reset to "0.0 g".
3. Add the items to be weighed into the container. The display will now show only the net weight of the items.

4.3 Unit Conversion

To change the weighing unit:

• Press the MODE button repeatedly to cycle through the available units: g, ct, lb, oz, dr, gn, ozt, dwt, MM, tl.J, tl.T, tl.H, t.
• The selected unit will be displayed on the screen.

4.4 Counting Function

The counting function allows you to count multiple small items of uniform weight.

1. Place a sample quantity of items (e.g., 10, 20, 30, 50, or 100 pieces) on the weighing pan.
2. Press the PCS button. The display will show the selected sample quantity (e.g., "10 PCS").
3. If the displayed sample quantity is not correct, press the PCS button again to cycle through the preset sample quantities (10, 20, 30, 50, 100).
4. Once the correct sample quantity is displayed, press the ON/OFF button to confirm. The scale is now in counting mode.
5. Add the remaining items to the pan. The display will show the total count of items.

Counting Tips: For items with individual piece weight less than 0.5g, consider taking multiple samples as a unit to meet the minimum weighing requirement. For items with individual piece weight greater than or equal to 0.5g, choosing a larger sample number (e.g., 100 pieces instead of 25) can improve accuracy.

4.5 Calibration Instruction

To ensure continued accuracy, periodic calibration is recommended.

1. Turn on the scale.
2. Press and hold the MODE key until the display shows "Load" and then the calibration weight (e.g., "5000.0" for 5kg).
3. Place the specified calibration weight (e.g., 5kg) onto the center of the weighing pan.
4. The display will show "PASS" once calibration is complete. Remove the calibration weight.

5. Maintenance

5.1 Cleaning

• The stainless steel weighing pan is removable for easy cleaning.
• Wipe the scale body with a soft, damp cloth. Do not use abrasive cleaners or immerse the scale in water.
• Ensure the scale is completely dry before storage or next use.

5.2 Storage

• Store the scale in a clean, dry environment away from extreme temperatures and humidity.
• If storing for an extended period, remove the batteries to prevent leakage.

6. Troubleshooting

• Inaccurate Readings: Ensure the scale is on a stable, level surface. Check for environmental factors like vibration, drafts, or electromagnetic interference. Recalibrate the scale if necessary.
• Display Shows "Lo": Batteries are low. Replace with new AA batteries or use the AC adapter.
• Display Shows "O-Ld": Overload. Remove items from the weighing pan immediately to prevent damage. The maximum capacity is 10kg.
• Unstable Readings: Ensure the item is placed centrally on the pan. Avoid touching the scale during weighing. Ensure the scale is designed for static weighing; adding liquid or powder to a container already on the scale can cause errors. Tare the container, remove it, add contents, then re-weigh.
• Scale Does Not Turn On: Check battery installation and charge level, or ensure the AC adapter is properly connected and functioning.
