Verify the balance shows the same
reading (within a tolerance depending
upon the model) when a mass is placed
at positions around the pan.
Verify the balance is acceptable
throughout the weighing range. The
balance must give acceptable readings
from low weights up to the capacity.
Inspect the area around the pan for hair,
dust or other obstructions,
*Inspection of the mechanics may be
needed for any possible problems.
Inspect the area around the pan for hair,
dust or other obstructions.
Re-check repeatability
*Inspection of the flexures for damage or
loose hardware may be required
*Use the Linearity Function in the service
menu to reset linearity
*A problem in the analogue circuit board
or power supplies can cause poor
linearity. Make sure all mechanical
problems have been eliminated first
*Check all flexures for damage
*Reset dealer calibration
*Verify linearity and repeatability
*The balance may be unstable. Verify
stability as above.
*Check the cables to the motor, try
plugging the balance into the power again
*Look for friction in the calibration weight
movement
*Check the opto-coupler that controls the
motor position.
Check parameters match the device
connected
Verify cable is correct
*RS-232 circuits damaged
*Check the cables to the display
*Replace the display which could be
damaged
