SECTION 6 OPERATION
6.1 ZEROING THE DISPLAY
You can press the ZERO/ENTER key at any time to set the zero point from which all
other weighing and counting is measured, within 4% 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. However you may need to press the
ZERO/ENTER key to rezero the scale if small amounts of weight are shown when the
platform is empty.
6.2 TARING
Zero the scale by pressing the ZERO/ENTER key if necessary. The zero indicator 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. 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 "TARE" 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. If the scale was tared
just before removing the container this value is the gross weight of the container plus
all product that was removed. The zero indicator will also be on because the platform
is back to the same condition it was when the ZERO/ENTER key was last pressed.
6.3 CHECK-WEIGHING
Check-weighing is a procedure to cause an alarm to sound when the weight on the
scale meets or exceeds values stored in memory. The memory holds values for a
high limit and a low limit. Either limit can be used or both can be used.
Press the LIMIT key. The display will show the current High Limit with the left most
digit flashing and the HI symbol on to the left of the display..
To change the value shown use the LIMIT/ to select the digit to change. Then
use the TARE/ key to increment the flashing digit. When the desired value is
shown press the ZERO/ENTER key to accept the value.
After pressing the ZERO/ENTER key the display will then show the Low Limit, the LO
symbol will be on to the left side of the display.
Enter the low limit in the same way the high limit was entered.
After pressing the ZERO/ENTER key the scale will return to weighing with the
