4.1 Basic Weighing

1. Press the ON/OFF button to turn on the scale.
2. Wait for the display to show "0.00" (or "0") before placing any items on the weighing platform.
3. Gently place the item(s) you wish to weigh onto the center of the stainless steel weighing platform.
4. The weight will be displayed on the LCD screen.

4.2 Unit Conversion

The scale supports multiple weighing units. To change the unit:

1. With the scale turned on and displaying "0.00", press the MODE button repeatedly.
2. The display will cycle through the available units: grams (g), grains (gn), ounces (oz), troy ounces (ozt), carats (ct), and pennyweights (dwt).
3. Stop pressing MODE when your desired unit is displayed.

4.3 Tare Function

The tare function allows you to subtract the weight of a container, so you only measure the net weight of its contents.

1. Place an empty container on the weighing platform.
2. Press the TARE button. The display will reset to "0.00".
3. Now, place the item(s) you wish to weigh into the container. The display will show only the weight of the item(s).

5. Calibration

Calibration ensures the accuracy of your scale. It is recommended to calibrate the scale periodically or if you notice inconsistent readings. A 200g calibration weight is required (not included).

1. Turn on the scale by pressing the ON/OFF button.
2. Wait for the display to show "0.00".
3. Press and hold the MODE button until the display shows "CAL", then release the button.
4. Press the MODE button again. The display will show "CAL" followed by the required calibration weight (e.g., "200.00g").
5. Place the exact 200g calibration weight onto the center of the weighing platform.
6. The display will show "PASS" and then return to normal weighing mode.
7. Remove the calibration weight. Calibration is complete.

Note: If you do not have a 200g calibration weight, you may need to acquire one separately for accurate calibration.

6. Maintenance

6.1 Cleaning

Wipe the scale with a slightly damp cloth. Do not immerse the scale in water or use abrasive cleaners. Keep the weighing platform clean and free of debris.

6.2 Storage

Store the scale in a clean, dry environment. If the scale will not be used for an extended period, it is recommended to remove the batteries to prevent leakage.

7. Troubleshooting

If you encounter issues with your scale, consider the following:

• Inaccurate Readings:
  • Ensure the scale is on a stable, level surface.
  • Avoid placing the scale near strong radio frequency interference.
  • Keep the scale away from high humidity, air currents (e.g., fans, open windows), and extreme temperatures.
  • Minimize vibration during weighing.
  • Perform a calibration (refer to Section 5).
• "Lo" or "Low Battery" Display: Replace the AAA batteries.
• "O-Ld" or "Overload" Display: The item on the platform exceeds the maximum capacity of 200g. Remove the item immediately to prevent damage to the scale.
• Scale Does Not Turn On: Check battery installation and ensure batteries are not depleted.
