sockets are connected in parallel.
• on
Dual mode for the use with dual-element (TR) probes;
the left-hand socket (red) is connected with the
amplifier input whereas the initial pulse is available at
the right-hand socket (black).
• through
Through-transmission mode for the use with two
separate probes; the receiver is connected with left
(red), the pulser is connected with right (black).
