Note) The available items depend on the weighing instrument and may not be available when the settings are fixed.
For a detailed description of the settings, refer to the instruction manual for the weighing instrument used.
2-2. Connecting the AD-8920A
(1) Refer to Table 1 shown above to confirm that the communication cable is of the correct type.
(2) Disconnect the AC adapter from both the weighing instrument and the AD-8920A.
Refer to the connection diagram shown above to connect the AD-8920A to the weighing
instrument, using the specified communication cable.
CAUTION
The D-SUB9 cable (standard or
accessory) is for use only with
the AD-8920A.
If used with an older AD-8920,
it could blow the fuse or cause
other damage to the weighing
instrument.
Attach the identification label
on the cable so that it will be
used only with the AD-8920A.

3. Display
3-1. Confirm that the AC adapter is of the correct type. Connect the AC adapter each to the weighing
instrument and the AD-8920A to turn the power on.
All of the display segments of the AD-8920A illuminate, and then the weighing data transmitted
from the weighing instrument appears. The status of the data is indicated by a triangle (ۂ).
Table 3 Symbol (
ۂ
) and data status
Position of symbol (ۂ) Status of weighing data
ST The weighing data is stable.
(-) The weighing data is negative.
Usually the minus sign is placed before a numeric value,
but for a 7-digit negative value, the symbol (ۂ) illuminates.
mom The weighing unit is momme.
ct The weighing unit is carat.
g The weighing unit is gram.
Note: The unit indicating ۂdoes not illuminate for weighing units other than
those described above.

3-4. If the power is turned on without a weighing instrument connected, all of the display segments will
remain illuminated.

4. Maintenance / Troubleshooting
4-1. Cleaning
For cleaning, wipe the AD-8920A with a soft cloth. Do not use solvents such as thinner.
4-2. If the display brightness is not even:
Turn the AD-8920A on without the weighing instrument connected. All of the display segments will
illuminate. Leave the AD-8920A this way for a few hours.
4-3. If the AD-8920A does not function properly: (Before asking for repair, check the following.)
࣭Is the AC adapter type correct?
࣭Is the cable connected firmly?
࣭Are the weighing instrument settings correct?
(Particularly, has the data output mode been set to stream mode, and the data format to A&D
standard format?)
࣭Is data other than the weighing data, such as time or ID number, being output?
