TROUBLESHOOTING

Shown below is a list of various phenomena of the AD-8922A and the remedies.

Table 7

Phenomenon

Cause and remedy

error10

appears.

•

The communications settings of the AD-8922A and the weighing

instrument are not the same.

Check the settings.

error11

appears.

•

The weighing instrument data format is incorrect.

Set the data format to A&D standard format. Also check whether or not
data other than weighing data is output.

The bar display
remains and no
weighing data
appears.

•

Is the weighing instrument in the stream mode?

Only the stream mode displays the weighing data continuously. Other
modes display the data only when received. When the hold display is
selected in the AD-8922A function setting, the previous data received is
displayed until the next data is received.

•

Are the communications settings correct?

•

Is the cable correct?

The display flickers.

•

Electrical noises may affect the display.

Using the grounding terminal located on the rear of the AD-8922A,
ground the AD-8922A.
