12.1. Notes On Maintenance
 Do not disassemble the scale. Contact your local A&D dealer if the scale needs
service or repair.
 Use the original packaging for transportation.
 Do not use organic solvents to clean the scale. Use a warm lint free cloth dampened
with a mild detergent.
 Calibrate the scale periodically to maintain the weighing accuracy.
12.2. Error Codes
Overload error
Indicates that an object beyond the weighing capacity has been
placed on the weighing pan.
Remove the object from the weighing pan.
Underload error
Indicates that the weight sensor receives a strong upward force.
Check if there is anything sandwiched around the weighing pan.
There is a possibility that the weight sensor or internal circuit
may have a problem.
Power-on zero error
Indicates that the power is turned on with a load beyond the
power-on zero range, or the weight value too unstable to
perform power-on zero. Remove the load, or check if there is
wind, vibration or anything touching the weighing pan.
Unit weight error
Indicates that total weight of samples is too light to set the unit
weight in the counting mode. Increase the number of samples
and try again
CAL error
Indicates that the calibration procedure is canceled because the
calibration weight is too light.
Check that the weighing pan is installed properly and the mass
of the calibration weight is correct.
Low battery
Indicates that the batteries have run out.
Replace them with new batteries.
