will have an arrow above it.

determine an accurate count.
Memory

4. BASIC OPERATION
4.1 Zeroing The Display
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 Weight 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
ZERO
to rezero the scale if small amounts of weight are
-2-
shown when the platform is empty.
4.2 Taring
There are two methods to enter a tare value. The first uses the
weight on the platform and the second uses a value input by the user.
4.2.1 Normal Tare
Zero the scale by pressing the
ZERO
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 "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. 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
key was last pressed.
4.2.2 Pretare
This method allows you to enter a value for the tare weight from the
keypad. This is useful if all containers are the same or if the container
is already full but the net weight is required and the tare weight of the
container is known.
Remove all weight from the platform, press the
ZERO
key to zero
the display.
