Diagnostic Commands
TEST Command
The TEST command causes the DT80 to perform a self-calibration, then run a series of self tests. Test results that are
out of range are flagged with a FAIL message.
This command can also be issued via the DT80 web interface .
A typical test report is shown below.

You can also request just one line of the report using
TESTn, where n is the line number (0-29, as indicated above). For
example, the following will return the firmware version number:

Some other useful test report parameters are described below:
• Product – this indicates the product type and series, for example DT80-2 indicates a DT80 Series 2.
• Serial number – this should match the number on the label affixed to the outside of the unit.
• VEXT – the voltage at the external power input.
• VBAT – internal battery terminal voltage.
• IBAT – internal battery current: positive when battery is charging, negative when discharging.
• VLITH – internal memory backup battery terminal voltage.
The other parameters listed in the test report are generally only useful to dataTaker service personnel. A description of
these entries is beyond the scope of this manual.
