+[title] Troubleshooting
+[* icon_caution] If the DO readings emit a reading of 0 mg/L then:
+[* black] Make sure the DO circuit board is facing the correct orientation (refer to step 2)
+[* black] Make sure that the jumper wires are connected correctly and securely. Likewise, check if the RX and TX wires are swapped.
+[* black] Check the connection between the adapter cable and the housing of the DO sensor to see if it is tight and sealed.
+[* black] Make sure there is adequate electrolyte solution in the cap of the DO sensor.
+[* icon_note] If the steps above fail, replace the DO sensor circuit board.
+[* icon_caution] If the DO readings emit a reading of 100,000 mg/L then:
+[* black] Replace the DO sensor circuit board.
