8.0 ERROR MESSAGES
When power is first applied to the scale a check is made to assure the A/D
counts are within a normal range. If an error is shown at this time the A/D
counts are either too high or too low.
EEEEE A/D counts at turn on are too high.
ADLOW A/D counts at turn on are below zero.
In either case, check the A/D counts as described above. Verify the load cell,
load cell wiring and the A/D counts are acceptable. Try to calibrate the scale
if the A/D counts are acceptable.
During normal operation, the display may show an error under these
conditions:
EEEEHI
Overload
EEEELO A/D value too low
Low battery, replace battery if used. Check the
external power supply if batteries are not used.
