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).
HOW TO WEIGHT A PRODUCT
PUT THE PRODUCT TO WEIGHT ON THE PLATE AND YOU WILL SEE THE WEIGHT IN THE DISPLAY AND THE
UNITS OF MEASURE IN THE UPPER RIGHT INDICATOR. FOR EXAMPLE IF YOU PUT A PRODUCT THAT WEIGHS
250 gr, YOU WILL SEE THE FOLLOWING:

EASY OPERATION
COUNT MODE
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
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 NOT
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
THE SCALE HAS 50 MEMORIES TO STORE THE UNIT WEIGHT VALUES OF PIECES.
HOW TO STORE UNIT WEIGHT MEMORIES
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 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.
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
TARE WEIGHT, AFTER YOU HAVE THE DESIRED TARE WEIGHT, PRESS 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 DOESNT KEEP THE TARE WEIGHT, BECAUSE
IS DESIGNED TO WAIT FOR TWO DIGITS.
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.

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.
