The Tare function allows you to subtract the weight of a container so that the display only shows the weight of the contents.
Vibration Extreme Temps Air Currents
ON/OFF MODE TARE LIGHT
Place an empty tray or container on the platform.
Press the 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

TARE again to return the display to zero.
Accuracy
Your scale comes calibrated from the factory and most users wont need to calibrate their scale for a long 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.
High Humidity
1. Prepare the required weight for your scale. (see chart on back)
2. Find a flat and level surface to perform calibration and let the scale adjust to room temperature.
High Humidity
3. Press ON/OFF to turn the scale on and wait for the scale to stabilize.
4. Press and hold the MODE key until the display shows ‘CAL’.
5. Make sure nothing is on the platform then press
MODE to confirm the zero point.
6. The display will then flash the required calibration weight.
Extreme Temps
7. Place the required calibration weight on the center of the platform.
8. The display will show
‘PASS’ then return to normal weighing mode.
You may now turn the scale off or continue weighing.
