7. Set the pan unit and I/O unit to adapt to the peripheral system. Set the following for the I/O unit.
RS-232C (Refer to
“
8. STANDARD INPUT AND OUTPUT INTERFACE
”
)
Set the weighing speed to adapt to the ambient conditions.
Note
Make sure that the personal computer is in operation before connecting to the AD-4212D.
8. After the balance has been installed, calibrate the balance using the internal weight or external
calibration weight. For details, refer to “4.2. Calibration”.
9. By removing the provided weighing pan, a locally fabricated weighing pan can be attached to the
AD-4212D series by using the four screw holes (M3 x 8) on the pan support.
MASS OF THE LOCALLY FABRICATED WEIGHING PAN
Design the weighing pan so that the mass falls within the ranges shown in the table below:
Model Status
Mass of
the weighing pan (g)
Pan support is used (with weighing pan removed)
10 to 21
AD-4212D-33/32
Pan support boss is used (with the weighing pan
and pan support removed)
35 to 46
Pan support is used (with weighing pan removed)
20 to 230
AD-4212D-302/301
Pan support boss is used (with the weighing pan
and pan support removed)
70 to 280
AD-4212D-33/32
AD-4212D-302/301
Notes
If the balance is to be used in a range other than shown above, contact the local A&D dealer.
To avoid the effects of static electricity or magnetism, use materials other than resin or
magnetic materials when designing a weighing pan.
When a locally fabricated weighing pan is used, the zero point may be shifted greatly
right after the AC adapter is plugged in. Perform re-zero before weighing to cancel the
amount of zero drift as necessary.
