Motion is present when trying to power up, print, zero or perform a
push button tare function. CORRECTIVE ACTION: wait for a stable
weight display ( STABLE annunciator on) before performing any of
these operations.
The weight on the scale exceeds the zero range when powering up.
CORRECTIVE ACTION: remove the excess load then press the
ON/ZERO key.
The scale deadload is less than the zero range when powering up.
CORRECTIVE ACTION: replace the scale platform or items
normally on the scale then press the ON/ZERO key.
The 748P is attempting to display a positive number greater than six
(6) digits in length or a negative number of more than five (5) digits.
CORRECTIVE ACTION: return to Gross Weight mode and review
Tare value. May indicate miscalibration.
The load on the scale exceeds the scale capacity plus nine (9)
divisions. CORRECTIVE ACTION: remove the over capacity load
from the scale platform. May indicate miscalibration.
EEPROM checksum failure. CORRECTIVE ACTION: recalibrate
with "C" numbers or weight.
An invalid keypad entry was attempted:
A. PRINT key pressed with a negative weight.
B. TARE key pressed to enter a Push button tare value of zero
or of a negative value.
C. ENTER key pressed to enter a Tare weight value that
exceeds the scale capacity.
D. ENTER key pressed to enter a Tare weight value that is
inconsistent with the scale's division value (i.e. attempt to
enter a tare of 123 with scale divisions of 5).
E. ZERO key pressed when the gross weight is outside the
scale zero weight range.
F. lb/kg key pressed to change to kilograms when the kilogram
Tare weight value exceeds four (4) digits in length.
CORRECTIVE ACTION: determine which of the reasons
for the error display is applicable and take the appropriate
corrective action.

Analog Error High

1. The load cell input is above the range of the indicator.
CORRECTIVE ACTION: Check for improper load cell wiring,
excessive load, and for output of 1 to 50mV.
2. Load cell or circuit failure. CORRECTIVE ACTION: consult your
scale serviceman.
