5. Setup

5.1 Installing the Weighing Pan

  1. Carefully remove the balance and all components from the packaging.
  2. Place the weighing pan support onto the central pillar of the balance. Ensure it is seated correctly and securely.
  3. Place the stainless steel weighing pan on top of the pan support.

5.2 Leveling the Balance

Accurate measurements require the balance to be perfectly level. Use the adjustable feet and the built-in level bubble:

  1. Locate the level bubble, typically found near the display or on the side of the balance.
  2. Adjust the four leveling feet at the bottom of the balance by turning them clockwise or counter-clockwise until the air bubble is centered within the circle.

5.3 Power Connection

The balance can be powered by either an AC adapter or a 9V DC battery:

  • AC Power: Connect the provided AC adapter to the power input port on the back of the balance and then plug it into a standard 100-240V AC outlet.
  • Battery Power: For portable use, open the battery compartment on the underside of the balance and insert a 9V DC battery.

5.4 Warm-up Time

For optimal accuracy, allow the balance to warm up for at least 30 minutes after connecting power or if it has been off for an extended period. This stabilizes the internal components for precise measurements.

6. Operating Instructions

6.1 Basic Weighing

  1. Press the ON/OFF button to turn on the balance.
  2. Ensure the display shows "0.00g" before placing any item on the pan. If not, press the TARE/ZERO button.
  3. Place the item to be weighed gently on the center of the weighing pan.
  4. Read the stable weight displayed on the LCD.

6.2 Unit Selection

The balance supports 10 different weighing units. To change the unit:

  • Press the UNIT button repeatedly to cycle through the available units: g (grams), ct (carats), oz (ounces), ozt (troy ounces), lb (pounds), TOL (tola), dwt (pennyweights), MM (momme), kg (kilograms), and % (percentage).
  • The selected unit will be displayed next to the weight value.

6.3 Tare Function

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

  1. Place the empty container on the weighing pan.
  2. Wait for the display to stabilize.
  3. Press the TARE/ZERO button. The display will return to "0.00g".
  4. Add the items to be weighed into the container. The display will show only the weight of the items.

6.4 Calibration

Calibration ensures the accuracy of your balance. It is recommended to calibrate the balance regularly or if it has been moved.

6.4.1 Standard Calibration

  1. Ensure the balance is on a stable surface and the pan is empty.
  2. Press and hold the CAL button until "CAL" appears on the display, then release.
  3. The display will show the required calibration weight (e.g., "2000.00g" for a 2kg balance).
  4. Carefully place the specified calibration weight (e.g., 2kg) onto the center of the weighing pan.
  5. Wait for the balance to stabilize and display "PASS" or return to normal weighing mode. Remove the weight.

Video 3: Demonstrates the standard calibration process using a single calibration weight.

6.4.2 Linear Calibration

Linear calibration uses multiple weights to ensure accuracy across the entire weighing range.

  1. Ensure the balance is on a stable surface and the pan is empty.
  2. Press and hold the CAL button for a longer duration than standard calibration until "CAL" appears, then release. The display may show a sequence of calibration points.
  3. Follow the on-screen prompts to place the specified calibration weights in sequence (e.g., 200g, 400g, 1000g, 2000g).
  4. Place each weight carefully and wait for the balance to stabilize before proceeding to the next step or removing the weight as instructed.
  5. Once all points are calibrated, the balance will return to normal weighing mode.

Video 4: Demonstrates the linear calibration process using multiple calibration weights.

6.5 Piece Counting Function

This function allows you to count a large number of identical items by weight.

  1. Place a sample quantity of items (e.g., 10, 20, 50, 100, 200, or 500 pieces) on the pan.
  2. Press and hold the PCS button until the display shows "PCS" and a number (e.g., "10 PCS").
  3. Use the UNIT button to select the sample quantity that matches the number of items you placed on the pan.
  4. Press the PCS button again to confirm. The balance is now in counting mode.
  5. Add more items to the pan, and the display will show the total count.

6.6 Percentage Function

The percentage function allows you to measure the weight of an item as a percentage of a reference weight.

  1. Place the reference item (100% weight) on the pan.
  2. Press the UNIT button repeatedly until "%" is displayed. The current weight will be set as 100%.
  3. Remove the reference item. The display will show 0%.
  4. Place other items on the pan, and their weight will be displayed as a percentage of the reference weight.

  • Inspection: Periodically check for any signs of damage or wear.

9. Troubleshooting

If you encounter issues with your balance, refer to the following common problems and solutions:

ProblemPossible CauseSolution
Display shows "Err" or unstable readingsOverload, unstable surface, strong drafts, electromagnetic interference, or internal error.Remove excess weight. Ensure balance is on a stable, level surface away from drafts and interference. Recalibrate the balance. If the problem persists, contact support.
Balance does not turn onNo power, dead battery, or faulty power adapter.Check AC adapter connection and power outlet. Replace the 9V battery if using battery power.
Inaccurate readingsNot calibrated, not leveled, warm-up time insufficient, or environmental factors.Perform calibration (Section 6.4). Ensure the balance is level (Section 5.2). Allow sufficient warm-up time (Section 5.4). Avoid drafts and temperature changes.
Piece counting is incorrectIncorrect sample quantity set, or items are not uniform in weight.Ensure the sample quantity selected matches the number of items placed on the pan. Use identical items for counting.
