Error Messages

Error messages may appear on the display when errors occur in the multimeter.
In remote operation, the current error list can be read by issuing the ERR? query.
When this is done, a string is returned containing the previously unread error
messages (up to ten) which are currently in the error message queue. When the
error queue is active, bit #7 of the Status Byte is also set to one.
Appendix A contains an explanation of the error messages which may be reported
by the OMM-6810B on the display or via remote operation.

Programming Examples

This section provides two simple examples of programming the OMM-6810B over
the GPIB.
Both examples are written in Quick BASIC for driving the National Instruments NI-
488.2 GPIB card. The first is an example of a "driver" for GPIB communications
with the OMM-6810B. The second is an example of how to remotely zero the
multimeter. These examples are not complete, and therefore cannot be used by
themselves. They do, however illustrate the simplicity of programming the 6810B.
The initialization of some variables and files have been purposely omitted.
The sample programs are shown on the next page.
