15. MAINTENANCE
15.1. 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.
The scale can be washed with water. The weighing platform has a structure that is
easy to wash and does not collect dust.
When cleaning with water, please use fresh water. Make sure that no water
droplets remain after cleaning.
Calibrate the scale periodically to maintain the weighing accuracy.
15.2. 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 the weighing pan is touching
anything or if there is anything in the base. There is a
possibility that the weight sensor or internal circuit may
have a problem.
Unit weight error
Indicates that the sample weight is too light to set the unit
weight in the counting mode.
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.
Low battery
Indicates that the HC-02i battery is depleted.
Charge the battery immediately.
