Troubleshooting

This section covers any problems that may arise when using the 777/788 systems.

• The indicator needs to see zero weight to register a change of weighing object

• The weight is more than zero and less than 20 intervals of the calibration of the 777/788 indicator. The weight may be too small for the system to register it as a valid weight to be printed

• Platform was unstable and in motion when the button was pressed

• The weight was not in the normal operation range, i.e. it was below zero or the platform was over capacity

• COM port settings of the printer on the 777/788 are different from the actual printer connection.

Technical information for scale engineers:

In some cases there is a chance that the hardware port from the PC or the 777/788 is damaged, or has internal problems. Please be sure that the port is physically working before requesting any software changes.

The easiest way to check both ports is to load the software into the 777/788 indicator from the PC via a download cable. If the download is successful then there is a bi-directional connection between the PC and the 777/788 indicator and all communications should work as expected
