Things To Avoid

Tare Function

The Tare function allows you to subtract the weight of a container so that the display only shows the weight of the contents,

Place an empty tray or container on the platform.| Pressthe POWER/ TARE key to subtract the container’s weight.| Add items to the container to see their weight on the display.

NOTE: The weight of the container will subtract from the available capacity and will leave a negative value on the display once the weight is removed. Press POWER/TARE again to return the display to zero.

Accuracy

Your scale comes calibrated from the factory and most users won’t need to calibrate their scale for along time. You should check your scale’s accuracy periodically using calibration weights and perform calibration if necessary.

NOTE: Only use trusted calibration weights.
Household items such as bottles and cans with weights printed on the side are not suitable for checking accuracy as these values are approximate and don’t include the container weight (Net Weight),

Calibration

**** Calibration adjustment is permanent and should only be performed using accurate calibration weights that match the requirements for your scale (see the chart on back). Do not use coins or other household items to calibrate.

1. Prepare the two included 10g calibration weights.
2. Find a flat and level surface to perform calibration and let the scale adjust to room temperature.
3. Press POWER/TARE to turn the scale on and wait for the scale to stabilize.
4. Press and hold the MODE/CAL key until the display shows ‘CAL’.
5. Make sure nothing is on the platform then press MODE/CAL to confirm the zero point.
6. The display will then flash “10.000g”.
7. Place the first 10g calibration weight on the centre of the platform.
8. The display will then flash %20.000g”.
9. Place the second 10g calibration weight (total of 20g) on the centre of the platform.
10. The display will show ‘PASS’ then return to weighing mode. Calibration is complete.
