BASIC PREPARATION

Т

FOR THICKNESS MEASUREMENT

1. Connect probe and select it in the probes list – PROBE → Probe type (add it to

the list if necessary);

Calibrate probe zero (for details refer to next pages)2. ; Set or calibrate sound velocity (for details refer to next pages3. ); Choose measurement type – MEASURE → Meas. type (0-1 by defaul4. t); Choose AGC mode MEASURE → AGC mode (Peak by defaul5. t);

Specify such Maximum Gain Mode (MEASURE → MaxGain mode) and value of 6. Maximum Gain (MEASURE → MaxGain) for manual mode, that Maximum Gain is high enough to raise back wall echoes at all thicknesses to be measured at necessary level and low enough that no noises come in the gate when probe is in the air;

Adjust scan and gate (for details please refer to the beginning of this guide) so 7. that back wall echoes at all thicknesses to be measured are in the gate limits;

Choose PRF mode (MEASURE → PRF mode)– High by default or other in case 8. if acoustic ghost signals are detected.

ADDITIONAL PREPARATION

Т

FOR THICKNESS MEASUREMENT

1. Choose measurement threshold (MEASURE →Threshold: Edge / 0-Edge);

Choose measurement mode (MEASURE → Mode: Conventional / Min & Max / 2.

Differential / % of wear) and specify rated thickness for “Differential” and

“% of wear” modes;

Specify measurement frequency;3.

Switch on measurement point marker (GTS & ALRM → Marker)(visible in 4. zoom mode);

Set alarm bounds (GTS & ALRM →Tmin and Tmax), alarm mode (GTS & ALRM →5. Alarms), visualization (GTS & ALRM →Show alarm zones) and sound (GTS & ALRM →Sound).

Probe

Zeroing in “on block” mode

Т

FREE CALIBRATION

Should be chosen in PROBE → Calibr.mode Prior to use free calibration all necessary preparations should be made and a thickness reading (can be incorrect) at the calibration block (or other object with known thickness) should be acquired.
