Note: if the main or Lithium battery are absent then there will be FAIL lines in the output from the normal TEST command but this will
not affect the overall pass/fail result.
 Power on Self Test
The TEST command is also run automatically, following a hard reset. If this test fails then
Self test failed
is displayed on the LCD in conjunction with two flashing LEDs, and a message is output to comms port and event log.
Press any key to clear the LCD message. You should then send a TEST command to see which particular test is failing.
If the power-on test passes there will be no indication (no report is generated).
Event Logs
To aid in troubleshooting, the DT80 automatically logs significant events into an event log, which is a text file
B:\EVENTS\EVENT.LOG. These events include:
• any of the errors listed under Error Messages (P418)
• USB memory device inserted
• external power connected or disconnected
• system time changed
• low power forced sleep
• communications errors
• logger reset
• safe mode (triple push) reset
• self test failure
• logger not characterised warning
• user defined messages, using the LOG "string" command
The event log may help pinpoint the cause of any unexpected readings or failures, and will be used by dataTaker
engineers if the DT80 is returned for service.
In the event of an abnormal reset due to a firmware error, the DT80 may store additional information in a companion file,
the error log (
B:\EVENTS\ERROR.LOG).
The contents of the event and error logs can be viewed using the UEVTLOG and UERRLOG commands.
They may also be viewed via the web interface.
The event and error logs can be cleared using the
CEVTLOG and CERRLOG commands.
STATUS Command
The STATUS command returns a report showing the status of the DT80's schedules, channels, alarms, memory and
logging to the host computer. A typical report is shown below:
