Troubleshooting

7.1

Troubleshooting instructions

The instrument routinely performs self-diagnostics and provides you with two levels of specific 
diagnostic information.

• Battery low indicator
• System error messages

Refer to the sections "Battery low indicator" and "System error messages" to localize and rectify a 
warning condition or an error.

7.2

System error messages

Normally, the cause of an error message is external to the instrument. The following table lists the 
error messages and their associated meanings:
