of the probe head. Attach the red lead of the mini-grabber to the signal
input and the black lead to the ground input of the probe head.

termination if the function generator requires such a load).
4. Attach a BNC cable to the unused female port of the BNC tee and connect

banana plug adapter into the DMM input. Be sure the side of the banana
plug adapter corresponding to the BNC shield (marked "GROUND") is
