Installing The Weighing Platform
Be sure to install the weighing
platform before using the scale.
To install the platform, place the
platform on the attachment point
located in the hole in the center of
the top panel. Insure that the the
bottom peg aligns with the hole on
the center of the attachment point.
Weighing Your First Item
1. Press the ON/OFF key to turn the scale on.
2. Place the item on the center of the weighing
platform.
3. Take your reading from the
display. You can press the
MODE key to convert between
weighing units.
4. The Auto-O feature will
turn the scale o after three
minutes of inactivity or you can
press the ON/OFF key to turn
the scale o.

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.
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.
1. Prepare the included 20g calibration weights.
2. Find a at 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 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 conrm the zero point.
6. The display will then ash “20.000g”.
7. Place the rst 20g
calibration weight on the
center of the platform.
8. The display will then
ash “40.000g”.
9. Place the second 20g
calibration weight (total
of 40g) on the center of
the platform.
10. The display will show
‘PASS’ then return
to weighing mode.
Calibration is complete.
