11-1. Notes on maintenance
Do not disassemble the scale. Contact your local A&D dealer if your scale
needs service or repair.
Use the original package for transportation.
Do not use organic solvents to clean the scale. Use a lint free cloth lightly
moistened with a mild detergent.
11-2. Error codes
Overload error
An object beyond the weighing capacity has been placed
on the pan.
Remove the object from the pan.
The scale has detected an excessive load.
Remove all objects from the pan.
Confirm that the weighing pan is correctly installed.
Underload error
The scale has detected an excessive upward force.
Check for anything trapped under the edge of the
weighing pan.
Unit mass / 100% reference mass error
The unit mass / 100% reference mass is too light in the
counting / percent mode.
Sample quantity error
When the sample weight is light and the counting error
could become large, the scale prompts you to use a
larger number of samples. Place the displayed number of
samples on the pan and press the MODE key to store
the unit mass.
Pressing the MODE key without adding
samples is possible, but that will reduce counting
accuracy.
When starting with the 100 samples,
100 -
may be displayed if the sample weight is light.
If so, press the MODE key without adding any
samples.
When the function setting “
aCai 0
” (ACAI
disabled) or “
Umin 2
” is selected, this error will
not appear.
