2. Powering the Scale

The scale can be powered using the included AAA batteries or an optional AC adapter (not included). For battery operation, open the battery compartment on the indicator unit and insert the 4 AAA batteries, observing polarity.

For continuous operation or when connecting to a computer, it is recommended to use an AC adapter (DC 6V, 500mA, center positive) plugged into the power input port on the indicator unit.

3. Connecting Components

Connect the weighing platform to the indicator unit using the coiled cable. Ensure the connector is securely inserted into the designated port on the indicator.

The indicator unit can be placed on a desk or mounted on a wall using the provided bracket for optimal viewing and accessibility.

Operating Instructions

1. Basic Weighing

1. Place the scale on a firm, level surface.
2. Press the ON/OFF/ZERO button to power on the scale. The display will show "0.00" when ready.
3. Place the item to be weighed onto the center of the weighing platform.
4. Read the weight displayed on the LCD screen.

2. Using the Display and Buttons

The indicator unit features a clear LCD display and several function buttons:

• ON/OFF/ZERO: Powers the scale on or off, and zeros the display.
• UNITS: Toggles between available weight units (e.g., lb, kg).
• TARE: Subtracts the weight of a container or packaging, allowing only the net weight of the contents to be measured.
• HOLD/PRINT: Holds the displayed weight or sends the weight data via the RS232 port.

3. Tare Function

To use the Tare function:

1. Place an empty container on the platform.
2. Wait for the weight to stabilize.
3. Press the TARE button. The display will return to "0.00", indicating the container's weight has been tared out.
4. Add the items to be weighed into the container. The display will show only the net weight of the items.

4. Computer Interface (RS232)

The scale includes an RS232 port for connecting to a computer or compatible shipping systems. This allows for direct weight data transfer to software like UPS Worldship or FedEx Ship Manager.

Maintenance

1. Cleaning

To maintain accuracy and longevity, keep the scale clean. Wipe the stainless steel platform and indicator unit with a damp cloth. Avoid using abrasive cleaners or excessive water, as this can damage electronic components.

2. Battery Replacement

If the display becomes dim or the scale does not power on with batteries, replace all four AAA batteries. Ensure correct polarity when inserting new batteries.

3. Calibration

The scale is factory calibrated. If you suspect calibration issues or experience consistent inaccuracies, it is recommended to contact Brecknell customer support or a certified scale technician for recalibration. Do not attempt to self-calibrate unless specifically instructed by official documentation or support.

4. Storage

When not in use for extended periods, store the scale in a dry, stable environment. If using batteries, remove them to prevent leakage and potential damage to the indicator unit.

Troubleshooting

Common Issues and Solutions

• Scale does not power on:
  • Check battery installation and ensure batteries are fresh.
  • If using an AC adapter, ensure it is properly connected and the power outlet is functional.
• Inaccurate readings:
  • Ensure the scale is on a stable, level surface.
  • Verify that nothing is touching the platform or interfering with its movement.
  • Check for debris under the platform.
  • Consider recalibration if issues persist (contact support).
• Display shows "OVERLOAD" or "Err":
  • Remove any excessive weight from the platform. The scale has a maximum capacity of 400 lb.
  • Power cycle the scale (turn off, then on again).

   • Press the ON/OFF/ZERO button to save all settings and exit setup.
2. PC Port Settings (Windows):
   • Go to Device Manager, then Ports (COM & LPT).
   • Double-click on the COM port assigned to your scale (e.g., COM1).
   • Go to the "Port Settings" tab and configure as follows:
     • Bits per second: 4800
     • Data bits: 7
     • Parity: Even
     • Stop Bits: 1
     • Flow control: None
   • Click OK and close Device Manager.
