4.9.3 Diam eff / WIDTH eff Setting the probe crystal effective diameter (for Disc or Unknown shape) or effective width (for Rectangle shape).

4.9.4 LENGTH eff/ Near Field Setting the probe crystal effective length (for Rectangle shape) or near field value (for Unknown shape). -6dB=X.X is the beam divergency angle at -6 dB drop.

4.9.5 PROBE DELAY Adjustment of probe delay line value (e.g. for dual element or angle probe) within the range from -10.00 s to 4800.00 s. The instrument calculates the probe delay value based on DELAY LEN and DELAY VEL values and shows the calculated value just below the PROBE DELAY value in gray as DLY: X.XX s. This calculated value becomes a stopper for manual setting of the PROBE DELAY.



PROBE Sub-Menu Items on the Screen Right Side:


4.9.7 ANGLE Adjustment of the angle value for angle beam probe OFF, 1.0 to 89.0.

4.9.8 X-VALUE Adjustment of the x-point of the angle probe 0.0 mm to 100.0 mm (this button is active only if the ANGLE is different from zero).

4.9.9 DELAY LEN Delay line length, e.g. for dual element or angle probe.

4.9.10 DELAY VEL Setting of the velocity of ultrasound in the delay line material.

Version 3.0 June 2011 / SW Version: 2011.06.09 Functions of Gates


5. Functions of Gates Default conditions are:

- GATE 2, 3, 4 OFF; - GATE 1 ON; - ANGLE OFF; - DAC OFF.

5.1 GATE 1

5.1.1 Available Modes of GATE 1 - ON 1 (positive logic) without any alarm; - ON + 1 + (positive logic) with acoustic alarm; - ON+AUX 1ax (positive logic) alarm and analog position of echo flank

on ANALOG OUT.

5.1.3 Functions of GATE 1 with Angle Probes

When the ANGLE function is ON and X-VALUE had been set in the Settings menu, some values are displayed using corrected metrics:

- (1) S= non-corrected sound path position of maximum echo peak (marked with blue cross ) within the GATE 1;

- (2) 1.P= position and height of first echo peak (marked with white cross) over the GATE 1;

- (3) D= calculated depth of the indication (maximum echo peak within the GATE 1, marked with blue cross );

- (4) maximum echo peak (marked with blue cross ) relative amplitude against the GATE 1 [dB] (not active in RF display mode);

- (5) maximum echo peak (marked with blue cross ) absolute height within the GATE 1 [% FSH];

- (6) P projection distance from the probe X-point to the maximum echo peak (marked with blue cross ) within the GATE 1.

5.1.4 Functions of GATE 1 with DAC Curve When any DAC function is ON, all amplitudes are measured against the basic DAC curve (DAC1), instead the GATE1 vertical position of the gate has no effect. In the Status window, the following values are displayed:

a) with ANGLE function OFF: (see also 4.6.7 or 4.9.7) - (1) DAC dB maximum echo peak

(marked with red cross ) relative amplitude against the DAC curve [dB] within the Gate 1;

- (2) AP maximum echo peak (marked with red cross ) absolute height within the GATE 1 [% FSH];

- (3) 0-P position of the maximum echo peak (marked with red cross ) within the Gate 1.

b) with ANGLE function ON: (see also 4.6.7 or 4.9.7) - (1) S= non-corrected sound path

position of maximum echo peak (marked with red cross ) within the GATE 1;

- (2) D= calculated depth of the indication (maximum echo peak within the GATE 1, marked with red cross );

- (3) DAC dB maximum echo peak (marked with red cross ) relative amplitude against the DAC curve [dB] within the Gate 1;

- (4) AP maximum echo peak (marked with red cross ) absolute height within the GATE 1 [% FSH];

- (5) P projection distance from the probe X-point to the maximum echo peak (marked with red cross ) within the GATE 1.

5.1.5 Other Functions of GATE 1 - Acoustic alarm may be switched ON, when the echo reaches or exceeds the

GATE 1 level or, with DAC switched ON, when the echo reaches or exceeds the DAC level within the GATE 1 (GATE 1 level has no effect, when DAC is ON).

- ON+AUX analog output may be switched ON. There is a signal on the AOUT1 output (LEMO Analog Out), with voltage corresponding to relative echo position within GATE 1:

minU = GATE1_BEGIN;

maxU = GATE1_END.

Note: If there is no echo within GATE 1, then maxU is on the output.



5.2 GATE 2

IMPORTANT: ANGLE and DAC functions shall be OFF for proper thickness measurement!!!

5.2.1 Available Modes of GATE 2 GATE 2 measures always against GATE 1, options are:

- OFF inactive not displayed;,

- THICKNESS AUTO 1P-1P 1st peak to 1st peak see 5.2.2 for details;

- THICKNESS 1P-1P 1st peak to 1st peak see 5.2.3 for details;

- THICKNESS F-F flank to flank see 5.2.4 for details;

- THICKNESS P-P peak to peak see 5.2.5 for details.

5.2.2 THICKNESS AUTO 1P-1P - GATE 2 in this mode cannot be moved

its positioning is automatic.

- Measuring gate is GATE 1. The position of first echo peak within GATE 1 (which exceeds GATE 1 level) is taken as the reference.

- Minimum THICKNESS shall be set in the right side of the GATES menu. This THICKNESS value (T>x.xx) is added to position value of first echo found within GATE 1 and determines a zone to search a second echo. This zone is indicated on the screen as GATE 2 with variable width, if at least first echo has been found within GATE 1.

- A first echo peak is now searched within GATE 2. Its position is indicated with cyan cross. The relative position against the reference is the resulting thickness, which is displayed in the Status window with dark blue colour.

- With proper GATE 1 position, width and minimum thickness setting, you can get automatic thickness gauge, operating within wide range, which doesnt require any operators intervention.

- If measured values are very unstable and their variation exceeds certain limit, then minimum measured value will be displayed, because highly probably there is some unwanted echo within the gate, which interferes with measuring.



5.2.3 THICKNESS 1P-1P - GATE 1 shall be positioned across first

echo, GATE 2 shall be positioned across second echo at discretion.

- When both gates are overpassed, thickness is determined by the difference between positions of first peaks of first echoes within gates.

- Measured echo shall be whole within the gate, i.e. gate shall not start inside the signal. Otherwise next whole echo (half wave) will be used.

5.2.4 THICKNESS F-F - GATE 1 shall be positioned across first


- When both gates are overpassed, thickness is determined by the difference between positions of flanks of first echoes within gates.


5.2.5 THICKNESS P-P - GATE 1 shall be positioned across first


- When both gates are overpassed, thickness is determined by the difference between positions of peaks of first echoes within gates.




5.3 GATE 3

5.3.1 Available Modes of GATE 3 - OFF,

- ON (positive logic) without any alarm, - ON + (positive logic) with acoustic alarm, - ON - (negative logic) with acoustic alarm - AUTOFREEZE any signal within GATE 3 level, which exceeds the gate level

for 1 sec. or more, will cause automatic freezing of actual picture (screenshot), indicated by the red indicator *FROZEN*. The picture then may be saved see 3.6.2. This function is used with SPOT WELD mode (optional).

5.3.2 Function of GATE 3 Intended use monitoring of back wall echo etc.

Fully independent GATE 3 may be switched ON in any operation mode of the instrument. It measures echo position and echo peak height (% FSH), marked with yellow cross. Values are displayed directly underneath the gate.

Acoustic alarm with positive and negative trigger logic may be applied.

There is a possibility of GAIN correction within GATE 3 for monitoring of back wall echo simultaneously with small defects detection.

Actual GAIN correction (GATE 3 XX.X dB) is displayed at the center of the right section of the display (instead the REJECT value) in the GATES menu with GATE 3 switched on (ON, ON + or ON -).

Notes: If required gain correction within GATE 3 cannot be executed due to actual setting of the attenuator and basic GAIN, a figure of the gain correction is displayed in red colour.

Info about actual gain correction is displayed with small text directly under GATE 3 ON.



5.4 GATE 4

5.4.1 Available Modes of GATE 4 - OFF; - ON (positive logic) without any alarm; - ON + (positive logic) with acoustic alarm; - ON - (negative logic) with acoustic alar
