Use blocks of wood connected to a binder clip to measure
the lift of the balloon. Pinch the neck of the balloon with the
binder clip to test the lift without having to tie the balloon.
Unclip the neck and add more or release some helium in
order to achieve the right amount of lift.

It is best if the spikes or peaks just reach to the top of the lower window or a bit beyond (become flat-topped). This is controlled by adjusting the volume on your receiver. As signals get weaker, they may not reach to the top any more – in that case, just turn the volume on the receiver all the way up.
Set this vertical red
bar to the highest
peak in the frequency
left to right.
Legible data with /
will show up in this
box after the red
vertical and horizontal

until it is cutting through the middle of the spikes and peaks.
Changes in color from red to green with a successful configuration.
Click the green arrow to move to the next step (or to back up).
1. Batteries: The AA batteries should be Energizer AA lithium cells. The 9-volt should be an Ultralife lithium battery. The sonde would probably work with an alkaline 9-volt, but would be likely to have problems with alkaline AA cells.
These instructions are to help with maintaining a good signal for the longest possible duration.
