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.

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 TARE again to return the display to zero.

Auto-Off

By default, the scale will auto-off after 180 seconds of inactivity. To change or disable the auto-off timer:

1. Turn the scale on and wait for the display to zero.
2. Press and hold the TARE key until the display shows the current auto-off setting (eg180), then release.
3. Press the MODE key to change the auto-off setting between 180 sec, 120 sec, 60 sec, or 0 sec (auto-off disabled).
4. Press ON/OFF to turn the scale off when finished.

Accuracy

Your scale comes calibrated from the factory and most users won’t 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.

Calibration

Calibration is permanent and should only be £.l.) performed using accurate calibration weights that match the requirements for your scale. Do not use coins or other household items to calibrate.

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.
3. Press ON/OFF to turn the scale on and wait for the scale to stabilise.
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.
7. Place the required calibration weight on the centre 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.
