Weston 330 lb Digital Scale - Manual (Page 6)

-6-
OPERATING INSTRUCTIONS
NOTE: To accurately weigh an item, place the item in the middle of the scale
platform. This will ensure the most accurate weight reading.
6. When weighing an item that exceeds
the scale’s overload or max capacity
(150 Kg/330 LB), the display will show an
“Err” message (Figure 5). To eliminate
the message, remove the item from the
scale and try again, using an item within
the confines of the scale’s capacity. If the
scale’s max capacity is exceeded for an
extended period of time, there is a risk of
permanent damage to the scale. Promptly
remove the over-capacity item when you
see the scale displays the “Err” message.
