exceedthedimensionofthe platter.
PREPARINGTO USE THE SCALE
1.Please locate the scaleona stable, level surfaceto ensure accurate weight readings.
2.Adjustthe four leveling feet tomake thebalancehorizontal. Makesurethatthe level bubble is
in the center ofthe circle.

4. Tare Function
(1)Putthe containeron the platter.When theweight displayed is stable, press the
key.Theweight ofthe container is thus deducted, andthe “Net”indicator is
on.
(2)Putthe object tobe weighed into the container,andthedisplayshowsthenet weight of
theobject.
(3)Removethecontainer andtheobjecttogether fromtheplatter.The display willshow the
negative value of thecontainer weight.
(4)Press thekeyagain,the negativevalueiscleared and the displayreturns to
zero. The “Net”indicator is off.
4Tare continuously:When the container weightincreasesordecreases continuously,it
canallbe deducted by pressingthekey.
4Tare value can beup tothefull capacityofthe scale.
5. Net/Gross WeightConversion
In the Tare mode, when the “Net”indicator ison, press thekeyonce.
The displaywill showthegross weight, the “Net”indicatorisoff,andthe Gross indicator “6”
ison.
Press thekeyagain,the displaywillshowthe netweight, the “Net”indicatoris
on, and the Gross indicator “6”is off.
Thusbypressing the key, the net weightandthe gross weightcanbe displayed alternately.

Press thekeyto select the “Pcs”unit,and the scaleenters the simple
counting mode.
6-2Sampling
Thisimportant procedureistolet thescale calculatetheunitweight:
(1)Press thekeyto select a sample size 10, 20, 50, 100 or 200.
(2)Put enough samples onto the platteraccording to the selectednumber, and then
press thekey.The displayshows “-- - - --”first.When the scale
becomesstable, the displayshows the number of sampleson theplatter.
(3)Removethesamplesfrom the platter,and thescale is readytocount.
6-3Counting
Place the objects tobe counted onto the platter,andthequantityshows on the display.
4When anyofthe following indicator is on,the scale can stillcount, but inaccuracymay
occur:
Sampletoosmall ( ): totalsampleweight isless than 20divisions
Unit weight too small( ):unit weight isless than 1/5 division.
4Thescalewill memorize the lastsample sizewhenswitchedoff,and the samecanbe
used when the scale enters the countingmode nexttime.
4If thenumberofsamples changesby5pieces from the lastsample used, thescalewill
calculate the newunit weight automatically.
