Page 5: The Keypad
2 THE KEYPAD Activates the primary menu structure containing 9 menu tab groups. These tab groups then contain sub menu items, or functions. The sub menu items are organised in tab groups according to how closely they are related to the indi- vidual tab group names. -
Page 6: Getting Started
The 6.35 mm (1/4") delay line provides more signal strength and may allow you to measure tough-to-penetrate materials. Information can be found on the Elcometer NDT Knowledge Centre on www.elcometerndt.com. 3.3 SWITCHING ON/OFF To switch on or off, press the on/off key The gauge will switch off automatically after 5 minutes of inactivity. - Page 7 4.1 FULL MENU Press once to then press scroll right access the menus... scroll to the right along to the desired function adjust the selected the sub menu bar and function to scroll left to the sub menu you want. 4.2 HOT KEY MENU Alternatively, adjust Press...

Page 8: The Measurement Screen
5 THE MEASUREMENT SCREEN Your gauge has four types of measurement screen: • A-Scan Waveform, RF • A-Scan Waveform, RECT • B-Scan • Digits A-SCAN B-SCAN DIGITS RECT To see the measurement screen, press MEAS. To select which measurement screen to use, press MENU, select DISP, select VIEW and then select RF, RECT, B-SCAN or DIGITS. - Page 9 Measurement View Area RF, RECT, B-SCAN or DIGITS view area. Measurement Labels Bar Displays the viewable range and are based on the values of DELAY/B-START and WIDTH/B-DEPTH Hot Menu The hot menu contains a selection of the most commonly used options, allowing you to conveniently adjust these to your needs while the graphical display is active 5.2 RF A-SCAN MEASUREMENT SCREEN...
- Page 10 • Change the values of the DELAY and WIDTH functions until the measurement falls inside the viewable range of the display - see instructions below. • Use the Auto Find function - see “Auto Find” on page 16. Note: Even if the waveform is outside of the viewable range of the display, a measurement can be taken and viewed using the DIGITS view.

Page 13: Setting Up The Gauge
7 SETTING UP THE GAUGE 7.1 TRANSDUCER - SETTING TYPE OF The first step in using your gauge is to select the transducer type from the predefined list of setups stored in the gauge. Selecting a transducer type and measurement mode optimises all gauge parameters for that particular probe. - Page 14 3. Apply a drop of couplant on the transducer and place the transducer as shown in diagram. Note: Disregard the value displayed; it is not important. What is important is accurately performing these steps to ensure reliability of the zero calculation. 4.

7.3.2 Known Velocity Calibration If the material velocity is known, you can enter the velocity value directly into the gauge. For a list of the sound velocities of common materials see “Sound Velocities of Common Materials” on page 27 1. Select MENU/CAL/VELOCITY and press ENTER to display the DIGITS EDIT BOX. 2. -

E-E mode, to activate Thru-Paint operation select this measurement mode using the MULTI MODE key and a delay line transducer. Further information may be found on the Elcometer NDT Knowledge Centre on www.elcometerndt.com. 11 MEASUREMENT - OPTIONS 11.1 AUTO FIND When using a scan type display, the DELAY and WIDTH (or B-START and B-DEPTH) must be set correctly for the waveform to be shown on the display. - Page 18 (above or below the x axis in the RF A-Scan) and the Rectified A-Scan display (whether the top or bottom half of the RF display is shown). For further information refer to the Elcometer NDT Knowledge Centre on www.elcometerndt.com. To adjust POLARITY: 1.
- Page 19 Memory capacity You can create and save as many data files as required up to the maximum capacity of the gauge memory (32 Mbit). If you try to create a new file which exceeds the memory capacity, the gauge will display an error message.
- Page 20 Note: If you try to save a reading into a cell location which already contains a reading value, a warning message is displayed (see Deleting a reading). 4. To advance to a specific row number, press OK enter the row number. Press OK to advance directly to that row number in the grid log.

Page 21: Gauge Setups
12 GAUGE SETUPS Your gauge contains 64 configurable preset locations in which you can store custom gauge setups, each one optimised for a specific measuring application. These gauge setups can save time when conducting routine inspections of the same job or project. This feature also helps to eliminate error between two or more users during the setup and calibration process. - Page 22 It is sometimes necessary to rename a previously saved setup, or add additional comments about a particular setup. The other comments about the project may also be required for additional documentation purposes. The following procedures outline the necessary steps for saving and editing a setup: 1.

Page 23: Data Transfer Software
13 DATA TRANSFER SOFTWARE Software is available which allows data to be transferred from your gauge to a PC. Presently Elcometer supplies ElcoMaster 2.0™ software for this purpose. To set-up other types of communications software: 1. Start the communications software. -
Page 24: Maintenance
The gauge does not contain any user-serviceable components. In the unlikely event of a fault, the gauge should be returned to your local Elcometer NDT supplier or directly to Elcometer NDT. The warranty will be invalidated if the instrument has been opened. -

Page 29: The Menu Commands
22 THE MENU COMMANDS Menu Function Description PROBE ZERO TRANS- Zeros your gauge in much the same way that a mechanical DUCER micrometer is zeroed. If your gauge is not zeroed correctly, all of the measurements made may be in error by some fixed value. - Page 30 Menu Function Description TUNE GAIN Increases or decreases the overall amplitude of the signal. Gain is similar to the volume control on a stereo receiver. When operating in echo-echo mode, the gauge adjusts the gain automatically. Alternatively, the AGC can be manually controlled.
- Page 31 Allows you to restore grid files saved on a computer to GRID your gauge via the RS232 port. ABOUT Provides Elcometer NDT contact information and your gauge software version. Refer to the help section of your gauge NDT Link software for a complete electronic manual covering data transfer.
