Connected like this you will see the pressure you are needing to create to inflate the tube i.e. the tube pressure.
I have the same pump. There is a knob on the top of the pump which switches the pump from one way to two way pumping, i.e. pressure on down stroke only or on both up and down strokes.
sorry for the late reply, but was abroad....
just tried using the pump as you instructed me, and it worked. thanks so much !!!
