Setting the Gate Work Mode
Two options for the gate work mode: SINGLE and E-E.
SINGLE: measures the distance from the surface to the peak echo.
E-E (Echo-Echo mode): measure the distance between two peak echoes (the
two peak echoes should be selected by two gates). It is very useful in thickness
measuring.
Use the GATE MODE function in the LOGIC submenu to select the gate work
mode.
4.11 Setting the Damping Level
This function serves for matching the probe. You can use it to adjust the
damping of the probe
’
s oscillating circuit and to consequently change the height,
width and resolution of the echo display.
- Activate the PULSER submenu (located in the P/R menu) by pressing
the menu key below it.
- Press the function key next to the selection titled DAMPING.
- To change the specified damping level and optimize the A-Scan signal
appearance, continue pressing the function key or turn the knob. You
’
ll
note that the following damping levels are available: 100
Ω
、
200
Ω
、
400
Ω
.
- The damping level will be set to the one last displayed.
4.12 Setting the Pulse Energy Level
Use the function ENERGY to set the pulser voltage. The relative energy with
which the pulser fires can be set to LOW, MEDIUM or HIGH.
The setting MEDIUM is recommended for most inspections. HIGH is used for
inspections in which maximum sensitivity is import, e.g. for the detection of
small flaws. Choose the setting LOW for broadband probes or if narrow echoes
are required (better lateral resolution).
To set the pulser energy
- Activate the PULSER submenu (located in the P/R menu) by pressing
the menu key below it.
- Press the function key next to the function titled ENERGY.
- Select the energy level by turning the knob or continuing to press the
function key.
