8.2 MAIN MENU ITEM DESCRIPTION
If in Pitch-Catch, RF or TONEBURST Mode
8.2.1 Gain
Gain can be changed via this menu item or the Direct Access Keys. As a matter of
convenience, the GAIN Direct Access Key can be used while in any other menu item
without re-scrolling through the menu to return to a previous position. The knob can
also be used.
8.2.2 RNG – RANGE
Selects the value of the total screen range. Start and stop values are displayed over
the waveform.
8.2.3 DLY – DELAY
This is the screen Delay or waveform position within the window
8.2.4 VLTS - VOLTS
Sets the desired drive voltage. Upper limit of voltage drive is determined by the probe attached.
8.2.5 GATE
Select GATE, Press ENTER to select & use the Up or Down Arrow Keys to select the cycle in the received signal
envelope. This will be the position the Phase measurements are taken and NULL(ed) from.
8.2.6 FREQ – FREQUENCY
Frequency is available only when the Tone Burst probes are attached and is not available when the LOW Frequency
(High Power) or broader banded probe is installed. To optimize the frequency to be used with a given material, place
probe on a good surface of the material under test and adjust the frequency up or down to attain a maximum amplitude
response. This will vary slightly for various materials, thicknesses and geometry. Generally speaking though, the
default value may work just fine.

8.2.7 PRB – PROBE
Returns to the power on screen to select another probe or setup. If in the top most menu item “AUTO” simply plugging
in a new (NDT Systems) probe will identify and select the attached probe. The selection options are then DEFAULT or
LAST. The BondaScope 350 keeps track of the last probe type connected in association with that probe type. It dos
not keep track of the specific serial number attached to the probe. So, for instance, if a probe model number PCHS31
were connected, removed and another PCHS31 were attached, the setup could be selected but due to minor
variances in the probe, slight adjustments may be required.
8.2.8 CYCLES
The number of cycles driving the probe in the Tone Burst Pulser. Set Cycles to optimize received signal envelope
symmetry and amplitude.
