10 INSPECTION TIPS & TECHNIQUES
10.1 Resonance Sample Setup Procedure
:
This is to provide a brief description for setting up and using a resonance probes on the Bondascope 350/350.
$
Select the proper resonance probe for the application
$
Select the BL8-S6 or BF11-S6 (350) Cable for use. Attach probe to Cable.
$
Plug Cable into appropriate connector socket located on the top panel of gage.
$
Turn gage on.
If AUTO-PROBE is on the screen will show that the probe part number (i.e. L3330, etc.) has automatically been
selected. If the probe is not automatically selected, a probe list will appear on screen to perform the following step(s):
$
Use the up/down arrow keys or the encoder knob to highlight “AUTO-PROBE” on the display screen. Press
“ENTER” on the keypad to turn on function. The screen display will show the probe part number of the probe
selected.
OR
$
Use the up/down arrow keys or the encoder knob to highlight the probe part number from the list of probes.
Press “ENTER” on the keypad to turn on function. The screen display will show the probe part number of the
probe selected. (Note: You will not be in the AUTO-PROBE Mode)
$
Use the up/down arrow keys or the encoder knob to highlight “DEFAULT”’ for a first time setup or “LAST” for a
previous non saved setup. Press “ENTER” (Stored setups can accessed in this matter.)
$
If DEFAULT is selected, the instrument will automatically go to, and perform a Probe BALANCING function.
This sets the resonant frequency of the probe as well as internal “best fit” parameters for gain and Analog to
Digital operational functions.
CALIBRATION
To set probe resonance frequency (balance):
1.
Press “SWEEP” on the front panel.
2. Highlight BAL in the menu and then press the ENTER key to balance the probe.
3. Press ENTER key again to accomplish and Air-NULL for conventional Resonance inspection.
4. Press RF/DOTS to return to the impedance display. (If the RF display is first apparent, press the RF/Dots
button again. Recall that this key acts as a toggle function key, in this case toggleing from RF to DOTS.
5. Place probe on an area of the sample considered good
6. Press NULL - this places the DOT in the center of the cross hairs. Any deviation from NULL will result in a
planar movement across the display
7. Enter the DOTS menu item to set and position any gating and alarming desired. Adjust gain and rotation as
required to get the best liftoff to defect separation
$
Optional Method: Place probe on “Good” area of cal standard. Press “NULL” on the front panel. Next, place
probe on defect area of cal standard. Press the “ENTER” key to accept.
$
Press SWEEP key again to enter into Swept Frequency Inspection Mode.
