BASIC PREPARATION
FOR THICKNESS MEASUREMENT
Т
1. Connect probe and select it in the probes list – PROBE → Probe type (add it to
the list if necessary);
2. Calibrate probe zero (for details refer to next pages);
3. Set or calibrate sound velocity (for details refer to next pages);
4. Choose measurement type – MEASURE → Meas. type (0-1 by default);
5. Choose AGC mode MEASURE → AGC mode (Peak by default);
6. Specify such Maximum Gain Mode (MEASURE → MaxGain mode) and value of
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;
7. Adjust scan and gate (for details please refer to the beginning of this guide) so
that back wall echoes at all thicknesses to be measured are in the gate limits;
8. Choose PRF mode (MEASURE → PRF mode)– High by default or other in case
if acoustic ghost signals are detected.
ADDITIONAL PREPARATION
Т
FOR THICKNESS MEASUREMENT
1. Choose measurement threshold (MEASURE →Threshold: Edge / 0-Edge);
2. Choose measurement mode (MEASURE → Mode: Conventional / Min & Max /
Differential / % of wear) and specify rated thickness for “Differential” and
“% of wear” modes;
3. Specify measurement frequency;
4. Switch on measurement point marker (GTS & ALRM → Marker)(visible in
zoom mode);
5. Set alarm bounds (GTS & ALRM →Tmin and Tmax), alarm mode (GTS & ALRM →
Alarms), visualization (GTS & ALRM →Show alarm zones) and sound
(GTS & ALRM →Sound).

FREE CALIBRATION
Т
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.
Probe
Calibrating probe zero (sound velocity is already set)
Н
Probe
Calibrating sound velocity (the probe is already zeroed)

1-POINT CALIBRATION
Т
Should be chosen in PROBE → Calibr.mode
Prior to use 1-point calibration it is necessary to specify the calibration
block parameters in OPTIONS → Block 1pt menu.
Probe
Calibrating probe zero (sound velocity is already set)
Probe
Calibrating sound velocity (the probe is already zeroed)

2-POINTS CALIBRATION
Т
Probe
Should be chosen in PROBE → Calibr.mode
Prior to use 2-point calibration it is necessary to specify the calibration
blocks parameters in OPTIONS → Block 2pts-1 and Block 2pts-2 menus.
Probe
Н1
Н2
Thicknesses of calibration blocks for 2-points calibration should differ
at least 2 times.
