Tare Weighing
The tare function allows you to subtract the weight of a container to obtain the net weight of its contents.
- Place an empty container on the weighing platform.
- Press the TARE key. The display will reset to "0.00" or "0.000".
- Add the items you wish to weigh into the container. The display will show the net weight of the items.
Calibration Adjustment
Calibration and adjustment are performed at the factory. However, the weighing range can shift slightly during shipping or due to changes in local acceleration of gravity. Adjustment is recommended when moving the scale from one location to another or if you suspect inaccuracies.
- Press the ON/OFF key to turn the scale on.
- Press and hold the MODE key until the display shows "CAL", then release.
- Press the MODE key again. The display will flash "CAL" and then the required calibration weight (e.g., "100.00g").
- Place the required calibration weight (e.g., a 100g calibration weight, not included) on the center of the platform.
- The display will show "PASS" then return to normal weighing mode. Calibration is complete.

Maintenance
Cleaning
To clean your scale, use a soft, damp cloth. Do not use abrasive cleaners or immerse the scale in water. Ensure the scale is dry before storage or next use.
Storage
When not in use, store the scale in a cool, dry place. The SWS100 features a protective cover that flips over the platform, ensuring safe and easy storage and protecting the weighing surface from dust and damage.
