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 scale’s auto-o function
will turn the scale o after 3 minutes of inactivity or
you can press the ON/OFF key to turn the scale o.
Counting Function
1. Place a sample quantity of 25, 50, 75 or 100 pcs of
the item you want to count on the platform.
1. Press and hold the PCS key to enter counting setup.
2. Tap the MODE key to select your sample quantity.
3. Press the PCS key to conrm the sample qty and set
the average piece weight (APW) in memory.
4. You may now place any quantity on the scale and
view the piece count. (‘pcs’ will show on the display)

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 required weight for your scale. (see
chart on back)
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 the required calibration
weight.
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 o or
continue weighing.
