FAQ

What is Zero value after power on?

It is zero value that records after the digits countdown from 9 to 0.

What is Zero value after calibrate?

It is zero value that records when doing specification calibration or weight calibration.

What is the zero range after press zero key?

± 2% of the maximum capacity.

What is Span Drift?

Temperature change effect on output

Express way：

TEMP. Effect on output: 0.020% R.O/10℃

R.O is Rated Output

For example：

15.000kg*0.005kg Its external resolution =15.000kg/0.005kg= 3000E

Change range of temperature：-10℃~ +40℃; temperature change in total:50℃

3000E * 0.02% * (50℃/10℃) = 3E = 3 *0.005kg=0.015kg

When using 1/3 capacity (equals to5.000kg) to measure:

(5.000kg / 15.000kg) * 3000E * ( 50℃ / 10℃ ) = 1E = 0.005kg

What is re-linearity?

It is also called repetitiveness. Methods of testing:

We test 3 times through testing linearity. The largest tolerance with standard value in testing.

Express way

tolerance of re-linearity < 0.0333333 % R.O

R.O is Rated Output

For example:

15.000kg*0.005kg Its external resolution =15.000kg/0.005kg= 3000E

To shift tolerance of re-linearity of external value= 3000E * 0.0333333% = 0.999999E ≒ 1E =0.005kg

Capacity: 0.000kg ~ 15.000kg; tolerance of linearity: ± 0.005kg

What is linearity?

It is the largest tolerance with standard value in testing. Usually, we represent the tolerance of Nonlinearity for linearity Express way: tolerance of Nonlinearity < 0.0333333 % R.O

R.O: Rated Output

For example:

15.000kg*0.005kg Its external resolution =15.000kg/0.005kg= 3000E

To shift tolerance of nonlinearity of external value= 3000E * 0.0333333% = 0.999999E ≒ 1E =0.005kg

Capacity: 0.000kg ~ 15.000kg; tolerance of nonlinearity: ± 0.005kg

What is unit weight insufficient?

In counting mode, the unit weight of sampling or the unit weight you input is less than 0.2E, the icon of unit weight insufficient.

What “OL,E1,E2,E4,E6,E7” stands for?

**【Price Computing Scale】**

The weight value is over 9 division of maximum capacity.

Zero value above 10% full scale.

Zero value below 10% full scale.

The internal value is over 350,000.

The internal value is below 80,000.

**【Counting Scale】**

Zero value is too high (OIML or NTEP > 10% full scale).

Zero value is low (OIML or NTEP < 10% full scale).

Internal value is more than 700000(use in factory calibration).

Internal value is lower than 100000(use in factory calibration).

The weight value is over 9d of the maximum capacity. (d=division).

Internal value is unstable

Unstable time is over 10 seconds after pressing ZERO or TARE key

**【Weighing Scale】**

The weight value is over 9 division of maximum capacity.

Zero value after power on is over +10% FS.

Zero value after power on is less than -10% FS.

Unstable zero return, unstable over 10 sec. Press zero key to leave E4.

Zero is too high when calibrating. (over internal value350,000)

Zero is too low when calibrating. (under internal value 80,000)

The scale is not in level status.(only available with level detector equipment.)

- - - - - - If the negative weight is over 20 divisions and there is no T or PT, the display shows- - - - - -”

What is auto unit weight averaging?

It is the unit weight which calculates quantities. It will modify the current weight automatically with adding quantities every time.

The condition of averaging unit weight: the quantities you add every time are less than current quantities on the platter.

Gravity effects on weighbridge

Gravity is the force that makes objects fall to the ground

Acceleration of gravity at the Equator：GE＝978.03184558cm/sec2

Acceleration of gravity at the Poles：Gp＝983.21772792cm/sec2

If the G value of someplace is the acceleration of sth. fall to ground, G value is not decreasegradually from mantle to centre of the earth, but G value becomes the maximum in thebottom of mantle and then it decrease to zero gradually.

The formula of G value in deferent latitude :

Gψ＝978.03185（１＋0.005278895sin2ψ＋0.000023462sin4ψ）

G value in different places

(1) Taipei：980cm/ sec2

(2) German：981.1cm/ sec2

(3) G value of Taipei/ G value of German：980/981.1=0.99887880949

(4) Set weight *0.99887880949 as the weight you must set

E.G. 1kg*0. 99887880949≒0.998kg you should input 998g and put 1kg to calibrate weigh

What is amplified factor value?

The weight displays under the load. E.g. put 1,000g, read out 995g which is the amplified factor value.

What is capacity?

The maximum value the scale can measure.

The capacities of our products including: 150g、300g、500g、 600g、1200g、1500g、3000g、6kg、7.5kg、12kg、15kg、30kg、60 kg、120kg、150 kg、300 kg、600 kg、1t、1.5t、2t、3t、5t
