COUNTING FUNCTIONS
TARE/ZERO KEY FUNCTION
1.- Reference to zero: it is possible that without having any weight over
the plate, the scale shows a number on the display due to voltage
variance or some other factor. When this happened, just press the key
and the weight indicator will return to zeros. The zero word appears in the
upper right indicator, this operation is the reset to zero.
Tare: this function is used when you wish to weight a product in a
container but you do not want to consider the containers weight during
the operation. To use this function follow steps: suppose you are going to
weight 150 gr. of some product in a plastic container that weighs 350 gr.
1. place the empty container on the scale.
8QC SERIES

2. Press the key. after some seconds the display will shows the
following:
3..Put the product inside of the container and the scale shows only the
products weight without the containers weight, when removing the container
will appear the negative weight.
If you finish weighting and you want to get out of this function, only press
the key, the scale will return to zero.
It is important to mention that this function is substractive from the scale´s
maximum capacity. for example, if you have a container that weights 350 gr.,
the scale will only be able to weight up to 19.650 kg.of product to complete
the maximum capacity. (20 kg).

Counting scale

EASY OPERATION
1.Press the , key.
2.Use the numeric keys to enter the weight per unit of the piece (unit weight).
3. Press the key.
The quantity of pieces is automatically calculated and it is displayed on the
count pcs section. If you do not know the exact unit weight you may use the
sample function and start counting after pressing enter. you can count up to
a maximum of 999,999 pieces. when it is exceding this quantity the total
of pieces displayed will be 0. When removing the excess of pieces the total
will display again the correct quantity of pieces.
SAMPLE MODE
You can use this mode to calculate the unit weight of one piece of the lot
you want to count.
1. Press the key. the maximum unit weight to calculate is 9999.9 gr. ;
9999.9 lb.
2. WHEN OPERATING THE SCALE IN kg.THE UNIT WEIGHT WILL BE CALCULATED
IN gr. The number of pieces of the sample depends on the unit weight. to
calculate the unit weight of a piece,
Place 10 pieces on the plate and divide by 10 the displayed total weight.
Then, check from the Tables of errors the minimum necessary quantity of
pieces for the sample to get a closer unit weight.
3. Place on the plate the necessary quantity of pieces and use the numeric
keys to enter.
The number of pieces of the sample. The unit weight is automatically
calculated and displayed on the unit weight display. You will be able to start
counting with this cell by
Pressing the key. To count using a remote cell you should press
local/remote after pressing the enter key. You can store the unit weight
value in a memory to use it later.
For example: let´s suppose that we shall weight screws and the unit weight is
Approximately 3.6gr. From the table of errors we know to get the minimum
error we should
Take at least 100 pieces for the sample. we press the key, we place
the 100 screws and we enter 100 using the numeric keys. The unit weight is
calculated and displayed now
Press the key and place the lot of screws to be counted, the quantity
of screws is displayed on the count pcs display. If high precision counting
is not required you may use a sample of 25 to 50 pieces for this example
but, the percentage of error will increase according to the table of
maximum errors.
10 QC SERIES

INTERMITTENT INDICATOR
It is activated when the total of pieces is calculated on the basis of the unit
weight value with more decimals that is shown in the unit weight section.
This value is not completely in the display, so you can not record it; when it is
required a better resolution is recommendable to make the sampling, calculating
the unit weight and counting the pieces for example:
The 100 pieces are placed and sampled as a sing le piece to know the
decimal unit weight.
When is indicating that they are 100 pieces the unit weight of the piece is
of 0.0005 in the display but internally the unit weight is of 0,000459 when
pressing enter after introducing 100 pieces via keyboard
The intermittent indicator of unit weight is displaying during all the operation
of the count of pieces and will make the count of total of pieces with the
internal unit weight of 0.000459.
If at this moment it keeps the value from unit weight, the value is 0,0005
and the operation of The total of pieces was made with this unit weight.
You notice the unit weight were nor calculated, the intermittent indicator is
not present and the total of pieces is calculated according to the unit
weight of the display

UNIT WEIGHT MEMORIES
HOW TO STORE UNIT WEIGHT MEMORIES
The scale has 50 memories to store the unit weight values of pieces.
It is posible to be in two ways, count or sample mode. Firstly in the sampling
mode obtain the unit weight following the procedure for it, once the unit
weight has been calculated correctly, press the key and enter the number
of the memory slot that you wish to save To ( from 01 to 50). In the same
way, entering the unit weight with the keyboard you can store memories in
the counting mode. In other words: introduce the unit weight, press the
and the memory number keys where it is desired to the unit weight (from 01
to 50). For example: if you want to keep the unit weight in the memory
number 01,do the following. When the memory number is captured press the
STO and keys, in this way the unit weight will be keept automatically. If
you press the key the scale did not keep the unit
Weight because this is designed to receive the combination of two numbers.
HOW TO RECALL UNIT WEIGHT MEMORIES
In order to recall the unit weight for some pieces that you want to count,
press the Key, and the number (from 01 to 50) corresponding to the
memory. For example: if it is required to recall the memory number 01, only
press the combination of and keys, then the unit weight will be
displayed.
The scale has 50 memories to store the unit weight values of pieces.
TARE WEIGHTS MEMORIES
The scale has 50 memories to store the tare weight values for containers.
HOW TO STORE TARE WEIGHT MEMORIES
It is posible to save a tare in two ways, tare mode or manual. In tare mode
first obtain the rare weight, after you have the desired tare weight, press
dsd key, with numeric keypad type the number of memory where you want
to save the tare weight (from 01 to 50, are the same memories for the local
and remote cells). Similar for tare manual, press key to enter the tare
weight with the numeric key pad, then press key and the number of the
memory where you want to save the tare weight (from 01 to 50).
Example if you want to save a tare weight into the one memory, follow this
steps, when you type the number of memory press and keys, so the
tare weight will be keept automaticaly. If you only press the key the
scale

HOW TO RECALL TARE WEIGHT MEMORIES
To recall a tare weight, press key, and the number of the memory (01
to 50).Example if you want to recall the one memory press and then
press and keys, the scale recall the tare weight from the memory.
Now you can make your countings.
HOW TO ACCUMULATE PIECES
This function is used to add pieces, however the maximum amount of
pieces to accumulate is 999,999. In the order to accumulate pieces while
in the counting mode, press the key, the display will show the
number of accumulated lot (itm) in the section weight and the total
amount of pieces accumulated in section count pcs., after a while the
display will returnwhere it was.
HOW TO SEE THE TOTAL COUNT
In order to see the total of pieces and the number of lot (itm) while your
scale is operating press the key at any time, the total was in the
display during a little while and returned to the display where it was.
when exceeding the storage cell sum (999.999 pcs.), the storage cell will
keep complete the last accumulated pieces and will send a double beeper
indicating that it can not accumulate more.
HOW TO ERASE THE TOTAL COUNT
When already there is accumulated a total of pieces and you wish to
erase the storage cell, just press the key , the display will display
zeros in the total amount of pieces accumulated during a little while and
will return to the display in which was previously.
OPERATION IN lb AND kg
If you wish to operate the scale in pounds press the key, in this
way your scale will Weight in the basis of pounds If you wish to weigh in
kg press again.

F. like the capacity of the scale is of 20 kg.in order to get the internal
division of 0.002 gr., the operation is the following: 20000 gr=20 kg. / 0.002
gr (20 kg./0.002 kg. = 10000) getting it 10000 divisions, that means,
capacity=20 kg. and divisions=10000. check in the selection table of minumum
external division the value in the table with the desired capacity, in this case
is of 20 kg. and the number of divisions are 10000, therefore the value in the
table is of 2.g. when appearing the zero message, check that the weight
sensor does not have anything on the plate; in this case when is pressing
enter, it will take the initial reference, after that press sample; immediately it
will have to put the weigh 2 kg.,with which one is going to calibrate and to
press enter.
5.- to get out of the configuration mode, turn off the scale and turn it on
again, so the scale works correctly and turn on the scale.
6.- verify the weighing.

RECOMMENDATIONS
Advantages and taking care of
1.- The scale offers the advantage at the same time to show the weight on
the plate, the unit weight of the piece and the total of pieces calculated in
the same display.
2.-Before initiating any weighing or sampling , it will have to verify the
optimal conditions of the sampling.
A) the scale has to be leveled.
B) the scale has to be isolated of currents.
C) the scale has to be isolated of airflows.
D) the scale has to be isolated of vibrations.
E) the scale has to be isolated of humidity and dust.
F) the motion indicator of display will have to be turned off.
G)the zero indicator in display will have to be turned on.
H) the section of display of weight showing zero weight.
3.-In order to fit the zero weight, press the zero key, this adjustment is made
just when there is a vibration absence.
4.-In order to avoid wrong references when making the sampling is recomme
nded to tare the container before making the sampling, if the container is
the same one for all the samplings with taring once the optimal conditions of
the sampling is enough.
5.-In order to obtain the greater possible resolution it is recommended to
sample the minimum pieces required according to the table of error and with
the unit weight
Calculated and verified to make the count of pieces.
6.- The error of count of pieces is based on:
A) the margin of error in the weighing according to the shown in d isplay
It is recommended to verify the optimal conditions of the sampling (2) to
reduce the error in the weighing.
B) the calculated margin of error of the unit weight according to sample
Verify the absence of the indicator of motion in the calculation of the unit
weight when pressing the enter key.
C) the margin of error of the weight between the same pieces.
Verify the difference of maximum weight between 0.01% pieces.
7. - The verification of the scale will have periodically to be made with a
weigh pattern and after some inadequate handling:
A) drop or hit the scale,
B) hit the weight sensor,
C) overload,
D) abrupt changes of temperature,
E) excessive humidity.
