Check the operation of weight /
temperature offset A/D.
(Refer to
“6-13, 1 Method of
identifying defects in the internal
offset mode
”)
In the T1 display of check mode
menu, check the absolute value
and dispersion (Refer to 6-7). If it
is NG further, replace and
reassemble temperature sensor.

Then if it is NG, the cause will be
the analog board assembly.
Replace the analog board.

If it is OK, the cause is the force
motor.
Check the force motor.

Then if it is NG, the cause will be
the analog board assembly.
Replace the analog board
assembly.

Pan
assembly
Check that the pan assembly is
correctly installed.
Install the pan assembly
correctly.
F
Check for foreign matter between
the pan and dust plate.
Clean the area around the pan
assembly and the dust plate.
F
Check that the dust plate does
not touch the pan assembly.
Install the dust plate correctly so
that it does not touch the pan.
F
Damaged
flexures
Check the condition of tension
and fulcrum flexures and lever.
Replace the parts and
reassemble the force motor unit.

Magnet
assembly
Check for dust particles between
the magnet and the force coil.
Clean the force motor assembly.
