batteries. Do not store the scale with batteries installed if it will not be
used for over 30 days to prevent damage from battery corrosion.

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, It is active within 4% of power up
zero. This will usually only be necessary when the platform is empty. When
the zero point is reached, the Weight display will show the indicator for zero.
The scale has an automatic re-zeroing function to account for minor drifting or
accumulation of material on the platform. However you may need to press
ZERO
to re-zero the scale if small amounts of weight are shown when the
platform is empty.
TARING
The Tare function is used to remove the package weight, effectively setting
the weight display to zero. If the item tarred is removed, a negative weight is
displayed. This allows weighing or counting only the contents of the
container.
There are two methods to enter a tare value. Normal Tare uses the weight on
the platform and Pretare uses a value input by the user.
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.
