6. OPERATION

6.1 AUTOMATIC ZERO UPON START-UP

The indicator has an "auto zero at start-up" function: in other words it means that if at start-up a weight within +/- 10%
of the capacity is detected, it will be zeroed; if the weight is not within this tolerance, the display shows "Err 4" and with
a non approved instrument the present weight after a few instants, while with an approved instrument "Err 4" is shown
continuously.

6.2 SCALE ZERO FUNCTION

You can press the ZERO key at any time to set the zero point from which all other weighing and counting is measured,
within +/- 2% of power up zero. This will usually only be necessary when the platform is empty. When the zero point is
obtained the display will show the indicator for zero.
The scale has an automatic rezeroing function to account for minor drifting or accumulation of material on the platform
(see step "F7 AZn", section 7.1). However you may need to press the ZERO key to rezero the scale if small amounts
of weight are shown when the platform is empty.

6.3 TARE FUNCTION

Zero the scale by pressing the ZERO key if necessary. The zero symbol will be on.
Place a container on the platform, a value for its weight will be displayed.
Press the TARE key to tare the scale when the weight reading is stable. The weight that was displayed is stored as
the tare value and that value is subtracted from the display, leaving zero on the display. The "NET" indicator will be on.
As product is added only the weight of the product will be shown. The scale could be tared a second time if another
type of product was to be added to the first one. Again only the weight that is added after taring will be displayed.
When the container is removed a negative value will be shown.
To remove the tare, unload the scale and press again TARE.

6.3.1 LIMITATION OF THE TARE FUNCTIONS

It is possible to limit the tare functions, selecting "oFF" in the F8 step of the set-up environment (see section 7)
The SEMI AUTOMATIC TARE could be made only if the tare is equal to 0.
NOTE: With approved instrument, the F8 step is not settable.

6.4 OVERLOAD MESSAGE

Please do not add item that is over the maximum capacity. When reading "- - - - - -" and hear beeping sound, remove
the item on the platter to avoid damage to the load cell.

6.5 COUNTING PIECES

Through the reference function it's possible to use the scale as a piece counter.
COUNTING PROCEDURE
The operations to be carried out are the following:
1) Place the empty container on the scale and press TARE to tare it.
2) Check that the zero is on the display and put the quantity of pieces chosen for the SAMPLE on the scale and
press the ZERO key at length
3) The display suggests a REFERENCE QUANTITY. The possible options are: 10, 20, 50, 100, and 200.
4) Press ZERO the number of times needed to reach the desired sample size.
5) Press TARE; the display will indicate "- - - - - -" and the indicator will calculate the Average Piece Weight (APW).
After a few instants the display will indicate the quantity selected put on the platform.
6) Add the rest of the items to count in the container and whose value will appear on the display.
7) Unload the scale, the APW will remain stored in memory for the next counting of similar pieces, without having to
repeat the REFERENCE operation.
8) Per cancel or to carry out a new reference operation, press the ZERO key at length and repeat the operations
as describe in point 1).
