surface.
• An object is contacting the sample being
measured, the measuring pan, or the tare.
• An error was made in the tare subtraction
procedure.
• The adjusters remain lifted, resulting in an
incorrect level.
• The indication values are inconsistent
after long hours of use, or because the
balance has been moved to a new
location.
• The limit function is not selected.
• The limit value has been erroneously
entered.
• Likely to produce errors in the counting
mode because the sample weight is
insufficient.
• Gross weight exceeded the capacity of the
balance (weight range = container +
weight of sample).
• A section of the mechanism is damaged.
• A foreign object is caught between the
measuring pan (pan base) and the balance.
• A section of the mechanism is damaged.
• The balance is exposed to static electricity
or noise.
• The electrical system of the balance is
malfunctioning.
• A weight heavier than the capacity was
used.
• The reference weight is less than 50% of
the capacity.
• Calibration produced an error of 1.0% or
more.
• Adjustment was performed with
something loaded on the measurement
pan.
• Mechanism was damaged for some
reason.
• The automatic power-off function was
activated.
• The battery capacity is low.
