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.
TARE
Place an empty tray
or container on the
platform and wait for
the stability indicator.
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
on the display once the weight is removed. Press
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 a long time.
You should check your scale’s accuracy periodically using
the included calibration weight 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 calibration weight.
2.
and let the scale adjust to room temperature.

scale to stabilise.
