Appendix IV

In Case of Difficulty

If the balance will no longer follow your instructions, unplug it from its

power source; then, plug the unit in again. If any unusual messages appear

during warm up, or if the balance does not return to normal operation,

contact your dealer or Setra Systems, Inc.

If the balance displays “–␣ –␣ –␣ –␣ –␣ –” for an extended period of time, or the

displayed reading is unstable, too much vibration or draft may be present.

Relocate the balance away from the source of vibration or shield the bal-

ance from draft. If it continues, service may be required.

If the balance displays ”nOCAL” during calibration, check to make sure you

are using the correct calibration weight. (This calibration procedure can

only correct for ± 1% span shift.)

If you are experiencing difficulty in calibrating or printing, check the set up

of the balance. To restore the factory default setups:

1. Hold down the TARE key then press the MODE key. Release both keys,

the display will read "FUnC".

2. Press the TARE key repeatedly until the display reads "FACdEF" for

factory defaults.

3. Press the MODE key. The balance should display “buSY” and return to

the normal weighing mode.

If the RS-232 interface does not function correctly, first make certain the RS-232

cable is securely fastened to both the balance and the peripheral device. Next,

reset the balance's baud rate and parity to match the external device and make

certain the data formats are identical. If data transmission or reception is still not

possible, check that the cable is the correct type. (It may be necessary to “cross”

the receive and transmit lines of the interface. That is, the receive line of the

balance must connect to the transmit line of the external device. Likewise, the

transmit line of the balance must connect to the receive line of the external

device. Special cables can be purchased for this purpose from a computer

dealer.) See Appendix II for detailed information.

If the problem still persists, contact your dealer or Setra Systems, Inc.
