PIECE COUNTING IN EXTRACTION
1) Load a FULL container on the scale and press "TARE" to tare it.
2) Press "MODE": The display suggests various REFERENCE QUANTITIES: 5,10,20,30,40,50,60,75,100,200
3) Press "ZERO" or "TARE" various times until the chosen quantity is displayed.
4) From the container take off the same number of pieces and press "ENTER/PRINT” to confirm. The display shows
"SAMPL" while the indicator calculates the Average Piece Weight. The display shows in negative the quantity extracted.
5) Continue the counting in extraction.
“Er.Mot” ERROR DUE TO WEIGHT INSTABILITY DURING THE SAMPLING
It may happen that during the sampling phase the weight is unstable and therefore it is not possible to correctly calculate
the APW. The “Er.Mot” is shown remaining for about three seconds. One should therefore repeat the sampling operation.
MINIMUM WEIGHT OF THE SAMPLE
It is advisable to use a reference quantity equal or greater than 0,1% of the scale capacity.
In any case, the weight of the reference quantity should not create an APW lower than the two internal points of the
converter (intrinsic limit of the instrument); if this condition takes place, during the sampling, the display will indicate for an
instant: "Error " and the quantity put on the plate will not be accepted. One should therefore use a higher reference quantity.
VARIABLE SAMPLE SIZE (REFERENCE QUANTITY) (only for 17-key indicator)
It is possible to insert directly by keyboard any reference quantity up to 999999 (not only the quantities proposed by the
MODE key).
- With the scale at zero, after having stored a tare, press “F”+ “5”; the display will indicate “n S" and then "0" or a
quantity already stored.
- Modify and/or enter the quantity (up to 999999) using the numeric keys.
- Follow the operations describe in point 5) in the COUNTING PROCEDURE section.
DISPLAY AND MODIFICATION OF THE AVERAGE PIECE WEIGHT (only for 17-key indicator)
It is possible to view or enter a known Average Piece weight using the keyboard. This can significantly speed up the
reference operations.
- With the scale at zero, after having stored a tare, press “F” + “6”, or the ENTER/PRINT key at length.
- The display will indicate " APW “ and then "000.000" or a previously entered value expressed with three decimal digits
in the programmed unit of measure.
- Enter the APW value with the keyboard (or leave the one present) and press ENTER/PRINT to confirm.
Example:
Unit of measure of the APW in g
000.000 means 000,000 g (for example APW = 001,050 = 1,05 g).
PRINTING IN THE COUNTING MODE
If the presence of a printer has been configured, each time ENTER/PRINT is pressed, while either weight or pieces are
displayed, one prints the data programmed in the SEtuP >> SEriAL >> CoM.Prn >> Pr.ConF of the set-up environment
(TECH.MAN.REF.); for example:
- GROSS weight
- TARE weight
- NET weight
- Quantity of PIECES (PCS) on the scale in that moment.
- calculated APW, expressed in the set unit of measure, with three decimal digits
12. INDICATOR CONNECTED TO PRINTER, FUNCTIONING BY BATTERY
In a system made up of an indicator connected to a printer in which both are battery powered, the printer, normally in
STAND-BY, will be powered only when one prints. When the printing is finished the printer returns to STAND-BY
automatically. This functioning is useful to reduce the energy absorbed from the battery when the printer is not used.
In this configuration if one has the need to maintain the printer powered in order to replace the paper and for other
operations:
-
Press the ZERO key for a few seconds.
- On the display the blinking “onPri” message will appear.
