8.3 Error Messages and Troubleshooting
Symptom Probable Cause Remedy
Ad------ Loadcell wires to indicator are incorrectly
connected, shorted, opened, ADC or loadcell(s)
are damaged. Make sure wires are ok and correctly connected.
Replace loadcell or ADC chip, Service required.
Ad______
0------ Weight reading exceeds Power On Zero limit. Make sure scale platform is empty. Perform zero
calibration.
0______ Weight reading below Power On Zero limit. Install platform on scale. Perform zero calibration.
-------- Weight reading exceeds Overload limit or the
weight value cannot be displayed in the current
unit of measure because it exceeds 6 digits. Reduce load on scale until weight value can be
displayed. Use a more appropriate unit of measure.
Re-set some parameters of CONFIG or USER.
________ Weight reading below Under load limit. Install platform on scale.Perform zero calibration.
EEP.E1 CONFIG or CAL parameters are not correctly
set. Re-set items in CONFIG, do calibration.
EEP.E2 USER parameter is not correctly set. Re-set items in USER.
CAP.ER Capacity parameters are not correct. Set PRIM.N/PRIM.d/SECND.n to correct number,
make sure capacity not more than 6 digit.
CAL.Er Calibration error. Input data or loaded weight is
too small, too big, unstable, non-linear. Input correct data, load correct weight onto
platform, Service required.
PWT.ER Piece weight is error, it's too small (<0.5d), The
weight on the platform is too small to define a
valid reference weight. Use a greater weight for the sample.
PCT.ER Unit-Percentage -Weight is error, it's too small
(the weight of 1%, 0.1%, or 0.01%-determined
by CONFIG-FUNC-PERCNT is less than 0.5d). Use more weight for the sample.
STB.ER USER-HOLD-STB.TIM is too short, USER-
HOLD-HLD.RNG is too small, other failure. Set USER-HOLD-STB.TIM longer, or set USER-
HOLD-HLD.RNG bigger. Service required.
Will not turn on. Power cord not plugged in or properly
connected. Power outlet not supplying
electricity. Battery discharged. Other failure. Check power cord connections. Make sure power
cord is plugged into the power outlet. Check power
source. Replace batteries. Service required.
Cannot zero the display
or will not zero when
turned on. Load on scale exceeds allowable limits. Load
on scale is not stable. Load cell damage. Remove load on scale. Wait for load to become
stable. Service required.
Cannot display weight in
desired weighing unit. Unit not set to enable or d≥5oz, when unit is
lb:oz. Enable unit in CONFIG-UNITS.
Battery symbol is empty
or Lo.bAt is shown Batteries are discharged. Charge batteries.
