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.
