Rectify
You can use this function to select the rectification mode
of the echo pulses according to your application.
RF (radio frequency)
There is no rectification. Both positive and negative
wave portions are displayed with true amplitude.
Full Wave
All half-waves are displayed above the base line on the
screen.
Positive HW
Only positive half-waves are displayed above the base
line on the screen.
Negative HW
Only negative half-waves are displayed above the base
line on the screen.
Dual Mode
You can toggle between single-element and dual mode.
Off
This setting is for single-element operation. The probe
must be connected to the
T/R socket (see page 51).
On
The dual mode is for using dual-element probes. The re-
ceiver must be connected to the
R socket and the pulser
to the T/R socket (see page 51).
Through
The through-transmission mode is for using two sepa-
rate probes in a through shot configuration.
The receiver must be connected to the R socket and the
pulser to the T/R socket (see page 51). As the sound
wave passes through the test object only once in
through-transmission mode, all range and wall thick-
ness measurement functions are adjusted accordingly.
TOF values are calculated for a single through path, not
for the pulse echo.
