1.
Insert the DO electrode into the top of right hole. And insert the 3.5mm Ø diameter phone jack ATC sensor plug
into the middle hole.
2.
Hold the BNC connector in one hand; with the other, insert the braid into the center of the connector. Continuing
pushing the braid into the connector until it will not go in any farther.
Do this gently and slowly; do not bend the braid.
3.
Turn the male BNC connector in a clockwise direction, until you cannot turn it any more.
