Page 11: Zero Calibration
3.1 ZERO CALIBRATION If the probe’s zero is not calibrated correctly, all measured values will have a fixed error. When the probe’s zero is calibrated correctly, the unit can measure the fixed value and correct all subsequent measurements accordingly. To zero calibrate, follow the below operation: •... -

Page 13: Function And Setup
velocity of a material is known, you can also press to open the INPUT VELOCITY GUI and directly input the velocity using Note: Ensure the probe and block are coupled tightly. 4 FUNCTION AND SETUP 4.1 MAIN MENU Press to open the main menu (shown in Fig. 4-1). MAIN MENU1 MAIN MENU2 SAVE... - Page 14 to navigate between the options. 4.1.2.1 CHECK To view your completed measurements, select SAVE in the main menu and then select CHECK using . The group and serial number can be inputted using 4.1.2.2 UPLOAD (suitable for USB gauge) To transmit all measurement readings to a PC via USB, follow the procedure as below: •...
- Page 15 4.1.2.4 DEL-GRP Delete selected data saved in the gauge’s memory using . Note that deleted data can’t be recovered. 4.1.2.5 SAVE-SET This option activates the manual save mode for a data set. First, set the size of each data set according to your requirements (five measurement readings are saved under the default setup).

Page 16: Limit (Alarm Measurement Mode)
4.1.3 LIMIT (ALARM MEASUREMENT MODE) In this mode, the user will be notified when the measurement either drops below a lower limit or exceeds an upper limit. To set the lower and upper limits, select LIMIT in the main menu using , set the upper limit using and press... -
Page 17: Diff (Differential Measurement Mode)
Fig. 4-3: Scan Measurement GUI 4.1.6 DIFF (DIFFERENTIAL MEASUREMENT MODE) Differential mode can be used to measure the difference between the tested object’s thickness and that of the reference value. Follow the procedure below: • STEP 1: Select DIFF using to change the reference value using (the default value is 10mm). -
Page 18: Avg (Average Measurement Mode)
enter the setup GUI. Input the material’s temperature using , and press to complete and return to the main menu (the high temperature measuring GUI is shown in Figure 4-5). Fig. 4-5: High Temperature Measurement GUI 4.1.8 AVG (AVERAGE MEASUREMENT MODE) Average mode is used to measure the average of several completed measurements. -

the screen. After completing all measurements, the average thickness will be displayed in the center of the screen. 4.1.9 STD (STANDARD MEASUREMENT MODE) Standard mode is a basic measurement mode that can be used to measure the thickness of a material. Select STD using and press to complete setup. -
Page 20: Auto-Off
using . Press to complete the measuring frequency setup and return to the menu. Note: If the gauge is turned off before the is pressed, the measurement rate will retain the previous current value. Note: The battery drain rate is increased when the measurement rate is increased. 4.1.12 AUTO-OFF The gauge is programmed to automatically shut-down after 3 minutes without operation. -
Page 21: Probe-Zero-Cal
using Note: If the gauge is turned off before the key is pressed, the language will not be changed but instead will retain the previous current units. 4.1.16 PROBE-ZERO-CAL Whenever the probe is changed, it is recommended to do a probe zero calibration to improve measuring accuracy and to ensure proper probe functionality. -
Page 22: Velocity Preset (Velocity Table)
select 2-POINT in the main menu using . The procedure for two-point calibration can be found in Section 3.2.2. 4.1.22 VELOCITY PRESET (VELOCITY TABLE) If the sound velocity of a material is known, calibration is not necessary and the velocity may be entered directly as a known velocity as discussed in Section 3.2.3 (the initial setup of the gauge is 5900m/s). -
Page 23: Dim (Pipe-Wall Measurement Mode)
4.1.24 DIM (PIPE-WALL MEASUREMENT MODE) If the thickness of a pipe wall is to be measured, please select this measurement mode from the main menu. 5 APPLICATION NOTES 5.1 FACTORS AFFECTING PERFORMANCE AND ACCURACY 5.1.1 SURFACE CONDITION Loose or flaking rust, corrosion or dirt on the outside surface of a test piece may interfere with the coupling of sound energy from the probe into the test material. -
Page 24: Calibration
Fig. 5-1: Correct positioning of probe against a small diameter cylindrical surface It is possible that on some severely corroded or pitted materials there will be spots where readings cannot be obtained. This can happen when the inside surface of the material is so irregular that the sound energy is scattered rather than reflected back to the probe. -
Page 25: Probe Selection
5.2 PROBE SELECTION For any ultrasonic measurement system (probe and gauge together) there will be a minimum material thickness below which valid measurements are not be possible. Normally this minimum range will be specified in the manufacturer’s literature. Generally, however, as probe frequency increases, the minimum measurable thickness decreases. - Page 26 °F °C °F °C High Temperature 1000 /540 °F °C Medium Temperature /260 • Make measurements quickly and allow the probe body to cool between readings. High temperature probes have delay lines made of thermally tolerant material, but with continuous exposure to very high temperatures the inside of the probe will heat to a point where the probe may be permanently damaged.

Page 27: Maintenance And Trouble Shooting
6 MAINTENANCE AND TROUBLE SHOOTING 6.1 ROUTINE CARE AND MAINTENANCE The case of the gauge is sealed to prevent intrusion of environmental liquids and dust. However, it is not completely waterproof and thus should never be immersed in any fluid. To clean the case, keypad and display window, use a damp cloth (and mild detergent if necessary). -
Page 28: Identify Probe Problem
6.3.3 IDENTIFY PROBE PROBLEM If the gauge doesn’t register the probe being plugged in, please first ensure that the probe is well connected to the gauge. If the gauge still doesn’t register the probe, please exchange the plugs and make sure they are well connected to the gauge. - Page 29 Acetic acid resin 2670 Nickel 5630 Acrylic acid resin 2730 Steel 330 5600 3230 Steel 4330 5850 Gold 3240 Iron, steel 5920 Phosphor bronze 3530 Titanium 6070 Silver 3600 Magnesium 6310 Qingcheng AE Institute (Guangzhou) Co., Ltd www.aendt.com Tel:86-20-32290092 Sales2@ae-ndt.com...
