When the scale is first powered on, it will perform
a test sequence. During this sequence, the
display will show the following:
• The model number and the software
revision level.
• A numeric counting test for all segments of
the display. During this test, a test of
Random Access Memory (RAM) and a test
of Read Only Memory (ROM) is performed.
If everything is OK, the display will show zero
weight and the scale is ready for use.

scale platter is empty and the display is at
zero. If it is not, press the ZERO key...
0.00 is displayed.
2. Place an item to be weighed on the scale
platter...
The scale will display the gross weight.
