Troubleshooting and Error Indications

The FB300 detects and reports several events and conditions that are considered errors. The FB300 will stop any run in process and display "EXX" where XX is one of the below listed errors. When the FB300 is displaying an error indication, press the gray ON/OFF key to clear the error and return to setup mode, or press the Run key to resume the run (after correcting the cause of the error). Note that loss of AC power during a run is considered an error condition. Always stop a run before turning off AC power to the FB300.
