Calibration and Tare

A new device does not need calibration

Calibration is primarily required after a repair or loss of factory calibration data. Do not use it as a general way to troubleshoot an incorrect weight reading.

Calibration

  1. Disconnect the external power supply.
  2. Place all weight sensors on a firm, level surface and leave the platform empty.

  3. Connect to the device access point and open General Settings → Scale Settings in its web interface.

  4. Start Zero Calibration and wait for it to finish without touching the platform.

    The screen shows two calibration stages:

  5. Select an available reference weight of 500, 1000, or 5000 g and place it on the platform.

  6. Start Reference Calibration and wait for the result.

Result: the device has saved the new calibration values. Check that the reference weight is displayed.

Tare

Taring excludes the weight of the platform or another permanent structure.

  1. Connect to the scales' web interface.
  2. Open General Settings → Scale Settings.

  3. Choose one method:

    • If the tare weight is known, enter it in grams and select Set Tare Weight.

      Entering a known tare weight

    • Alternatively, leave the structure on the sensors and accept the current value as zero.

      Accepting the current weight as zero

  4. Check the reading when finished.

Result: the device subtracts the tare from subsequent measurements. Taring does not change the factory calibration factor.
