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.
