PREFLIGHT CONNECTION TEST OF ELECTRICAL SYSTEMS ONBOARD DRONES.Slide2
Step 1:
Check
connection
between
positive pole from battery and all positive connections on PDB: There are in total 6 ”+” connections on the PDB.Make a note of measured resistance on your excelsheet diagrams first row marked ”Page 2, Step 1, point no 1”.

Step 2:
Check
connection
between
negative pole from battery and all negative connections on PDB: There are in total 8 ”-” connections on the PDB.Make a note of measured resistance on your excelsheet diagram on the second row marked:”Page 3, Step 2, point no 1”.

Step 3:
Check
crossconnection
between
positive pole from battery and the negative pole from the battery.Use the semiconductortest function on your DMM.Make a note of measured END voltage on your excelsheet diagram on the
third row marked:”Page 4, Step 3, point
no. 1”.Repeat the steps above, BUT change polarity
on your instrument: Positive on isntrument to ”LIPO -” on the PDB and the negative from your instrument to ”LIPO +” on the PDB.
Make a note of measured END voltage on your excelsheet
diagram on the third row marked:”Page 4, Step 3,
point no. 2”.

Step 4:
Check
connection
between
the ”12V” and ”GND”, make a note of the measured resistance in your diagram.Check connection between the ”5V” and ”GND”, make a note of the measured resistance in your diagram on the fourth row marked:”Page 5, Step 4, point no 1 & 2”.

1: 12V outletSlide6
Step 4:
Check
connection
between
the ”12V” and ”5V”, make a note of the measured resistance in your diagram.Check connection between the ”12V” and ”5V” using the semiconductor test – make an note of the measured voltage in your diagram.Change polarity and check again as mentioned
above.

Step 5:
Does all make sense?
Double check
everything
and
compare with another drone – If available.Upload your result on Slack so everyone can compare theirresults with yours.
