ID ERROR

Weight on scale is greater than calibrated capac-
ity range.

Displayed weight is less than calibrated capacity
range.

ID number 0 cannot be stored. ID number must
be a positive integer.

Configuration settings relating to scale capacity,
divisions, grads, or decimal pt. have been changed.
Recalibrate scale using current settings.
No tolerances have been entered for the dis-
played ID register.

Buffer 90% full.

Buffer 100% full.

No load cell signal present.

Cannot display lb/oz data in 6 display digits.

CAL SP value must be greater than 20% of full
scale.

Less than 0.3

V/grad signal is present.

Keypad button X is not producing a signal.

Keypad button 0 = target error.

Keypad button 1 = print error.

Keypad button 2 = zero error.

Keypad button 3 = over error.

Keypad button 4 = ID error.

Keypad button 5 = tare error.

Keypad button 6 = units error.

Keypad button 7 = under error.

EEPROM checksum failure. CW-80 has de-
faulted to original units.

EEPROM write failure. Unable to write to ID
selected.
