EPOCH XT Transducer Connections

BNC or Large LEMO transducer posts are available at the same price.

BNC connectors are designed to be sealed to IP67. Caps are provided to protect unused connector in wet environments LEMO connectors do not meet IP67. Will be supplied with a protective rubber cap, but these still must be protected from water. Standard size LEMO connectors for IP67 are not available but we are pursuing other connection possibilities.

It is possible to switch connector types, this must be performed at an authorized Olympus NDT service center.12

EPOCH XT IP67 Environmental RatingThe EPOCH XT is designed to meet the requirements of IP67

This test means that the instrument can be submerged in 3 ft of water for 30 minutes and no liquid will enter the case. This test has been conducted and passed several times. The instruments actually float and must be weighted down to conduct the test.

HOWEVER

ONDT does not recommend that operators submerge their instrument for any reason. The EPOCH XT is not suitable for use underwater. ONDT will not cover internal water damage under warranty in most cases. The IP67 rating is intended to provide a concrete specification that communicates the environmental durability of the instrument. Operators must still use their best judgment before exposing the instrument to a harsh environment. 13

Over 100dB for all filter settings Full gain adjustment on frozen waveforms. Amplitude measurement accuracy of 0.25% Unprecedented TVG performance with 110dB of dynamic gain in a setup and 100dB/usec slopes between points. *depends on filter setting

Unique EPOCH XT only features:

22

Digital Receiver FiltersDigital Receiver Filters provide many advantages over the analog filters used in competing equipment and in the EPOCH 4 series. Advantages include:

Highly accurate filter performance Elimination of variability due to components New and/or custom filters can be created and implemented through software updates. *This is not going to be a free service. If a customer is interested we would have to quote this as an added-cost feature.

23

First Peak MeasurementThe EPOCH XT is has three built in measurement modes:

Highest Peak (Peak) Measurement Edge (Flank) Measurement First Peak Measurement

First Peak Measurement measures the first peak in Gate 1 or Gate 2. This feature is typically used to make accurate thickness measurements on thin materials.

COARSE

In order to speed up adjustments with the Arrow keys, the EPOCH XT has a new feature that allows most parameters to be adjusted in Coarse or Fine increments with the Arrow keys. The UP and DOWN Arrow keys are used for COARSE adjustments. The LEFT and RIGHT Arrow keys are used for FINE adjustments. In most cases, the coarse and fine steps have been defined for the operator. For the GAIN adjustment the operator may set his preferences in the INST SETUP Menu EditPara TAB. The default setting is 6dB for Coarse steps and 0.1dB for Fine steps.29

New Keypad FunctionsDelay Function:DELAY

The EPOCH XT has a new Delay function, also known as Display Delay. This function is used to move the time (distance) area that is currently viewed onscreen without affecting the calibrated zero offset position. This feature has been available on competing instruments for quite awhile, but the EPOCHs have only had a ZOOM function available. The EPOCH XT also retains the ZOOM feature for Gate 1.

EPOCH XT Color SchemesThe Factory Color Scheme is the default setting for the EPOCH XT.

This color scheme provides excellent indoor visibility. It has been designed to provide color differentiation between parameter labels, settings, and units, and also between measurement icons and the displayed readings. 36

EPOCH XT Color SchemesThe screenshots below show the Outdoor Color Scheme.

The Outdoor Color Scheme is designed to allow good display visibility in direct sunlight.37

EPOCH XT Color SchemesThe ELD Color Scheme is shown in the screenshots below.

The ELD Color Scheme is an alternative to the Factory indoor color scheme. This scheme has been designed to be similar to the ELD displays in previous generation equipment with some improvements.38

EPOCH XT Grid Modes

The EPOCH XTs grid display modes have been enhanced to meet global market needs and competitive instrument features. The X-Axis has three display modes:

Standard: 10 equally spaced grid lines. Same as EP4 series SoundPath: 5 equally spaced grid lines that show sound path measurements. Based on Delay and Range settings. Leg: This mode displays up to 5 grid lines labeled LEG1 to LEG5. These grid lines correspond with the skip distance for your angle beam setup.

The Y-Axis has two display modes:

100%: Displays amplitude from 0 to 100% screen height just like the EPOCH 4 Series. Amplitude is measured to 110%. 110%: Displays amplitude from 0 to 110% screen height. Allows easy instrument setup to 100% for linearity or other system checks.39

42

EPOCH XT Setup Menus

The EPOCH XT has three setup menus that are used to control various instrument functions.

DISPLAY SETUP MEAS SETUP INSTR SETUP

This strategy has been implemented because the EPOCH 4 series menu has gotten complex and many levels deep. The three separate menus organize functions more logically. This structure also allows us to take advantage of a tabbed menu structure similar to the MG2 / 35 series instruments.

43

EPOCH XT Setup Menu Structure

All of the menus in the EPOCH XT have been organized in a similar manner and the navigation within the menus is standardized. There are four types of controls that are found within a menu:

TABS SUB-LEVEL TABS CONTROL GROUPS PARAMETERS

Navigation and adjustment is accomplished by using the arrow keys and the enter key. In some cases the operator may use the direct entry method to enter parameter values if desired.

NOTE: Full instructions for menu navigation can be found in the instrument operating manual.44

EPOCH XT Setup Menu NavigationTABS run across the top of the display when the operator enters one of the setup menus:

The operator uses the Left and Right Arrow keys to move from one tab to the next. The active tab is highlighted by the instrument. The operator presses the [ENTER] key to select and move into a TAB.

45

EPOCH XT Setup Menu NavigationSUB-LEVEL TABS run vertically on the left side of the display. These are only present in some of the EPOCH XT TABS. In the screenshot to the left the operator has already selected the TAB EditPara by highlighting it and pressing [ENTER].

The operator is now navigating through a set of vertical SUB-LEVEL TABS. He must use the Up and Down Arrow keys to select a tab (highlight it), and press [ENTER] to enter the SUB-LEVEL TAB.Pressing [2nd F], [ENTER] will bring the operator back to the EditPara TAB.46

EPOCH XT Setup Menu NavigationCONTROL GROUPS are sets of PARAMETERS that have been grouped together based on their function. These are located within TABS or SUB-LEVEL TABS depending on the setup menu. CONTROL GROUPS are usually surrounded by a box for visual reference. In the screenshot to the right you see the Meas TAB in the MEAS SETUP Menu. This TAB contains two CONTROL GROUPS. CONTROL GROUP 1 CONTROL GROUP 247

EPOCH XT Setup Menu NavigationIn this example the operator has used the Left and Right Arrow Keys to select the Meas TAB. To enter the first CONTROL GROUP he must press [ENTER]. To enter the second CONTROL GROUP he must press [ENTER] again. Since there is no third CONTROL GROUP in this TAB, pressing the [ENTER] key again will bring the operator back to the Meas TAB.

1st [ENTER] Press

2nd [ENTER] Press

3rd [ENTER] Press

48

EPOCH XT Setup Menu NavigationPARAMETERS are selected (highlighted) using the Up and Down Arrow keys. They are typically adjusted using the Left and Right Arrow keys, but in some cases the operator may use direct entry.

In the screenshot to the right the operator has used the [ENTER] key to select CONTROL GROUP 2, and the Up and Down Arrow keys to select the X Value PARAMETER. The Value of the X Value PARAMETER is adjusted using the Left and Right Arrow keys, or by pressing [ALPHA/NUM], entering the desired value, and then pressing [ENTER].

EPOCH XT DAC/TVGThe EPOCH XT DAC/TVG feature is standard in all instruments. This feature is similar to the Advanced DAC/TVG option in the EPOCH 4 series instruments with improvements. DAC/TVG Operation Modes: ASME ASME III CUSTOM JIS 20-80% TVG Table

61

EPOCH XT DAC/TVG ActivationDAC/TVG is setup and activated in the MEAS SETUP menu under the Options TAB as shown in the screenshot below: Once the desired DAC/TVG mode has been selected the operator presses the [MEAS/RESET] key. The operator will be returned to the live screen and the EPOCH is ready to acquire DAC/TVG points.

62

EPOCH XT DAC/TVG SetupThe DAC/TVG Setup Procedure is the same for ASME, ASME III, Custom and JIS DAC modes.DAC/TVG Setup Steps:1. 2. 3. 4. 5. 6. Position Gate 1 over the first echo. Press [F5] (Auto 80%) Press [F1] to capture the point Position Gate 1 over the next echo Repeat steps 2-4 until all points are captured. Press [F4] (DONE) to complete the setup.

Other Functions: 63

DELETE Deletes the last captured point. ERASE Erases the entire DAC/TVG setup.

EPOCH XT DAC/TVG OperationOnce the DAC/TVG points have been captured the operator is ready to use the instruments DAC/TVG setup. The curves are fully dynamic with Range, Delay, Gain, and Zoom. The F-Key Functions are:F1 = DAC/TVG View Switches between the DAC and TVG views of the setup. F2 = DAC/TVG Gain Allows the operator to move the DAC/TVG curves and the echoes vertically to achieve accurate and code-compliant defect sizing. F3 = Gain Step This parameter sets the adjustment step for DAC/TVG Gain.

F5 = Next DAC/TVG Rotates through the available DAC/TVG curves. Measurements are taken based on the currently selected curve (double thickness on screen).64

Special DAC/TVG Modes - CustomThe Custom DAC/TVG feature allows the operator to setup up to three warning curves (plus the main curve) from +10dB to -24dB from the main curve. The operator must choose the number of curves in the activation procedure. After that, the setup is the same as ASME DAC.

65

Special DAC/TVG Modes 20-80%20-80% DAC uses a combination of DAC and TVG to keep the DAC curve between 20% and 80% screen height. The only difference in the setup procedure is that the operator does not use the Auto-80% feature before each point is captured.

66

Special DAC/TVG Modes TVG TableThe TVG Table in the EPOCH XT is an advanced feature that is used to create fully customized TVG setups. These setups are not linked to any DAC setup. Typical uses include:

Building custom TVGs for immersion inspection Building TVGs for large forging inspections using DGS/AVG diagrams for the transducer that will be used Suppress Interface and Backwall echoes to achieve better near and far surface resolution. Eliminating near surface noise in materials like composites while using high gain in the far field to see clearly see the backwall and far surface defects.

67

Special DAC/TVG Modes TVG TableIn the example below the TVG Table is being used for three purposes: Equalize defect echo heights throughout the test piece Suppress the interface echo when the sound enters the test piece. This allows near surface defects to be detected. Suppress the backwall echo so it can be monitored on-screen and to allow detection of far surface defects.

68

Special DAC/TVG Modes TVG TableTVG Table Specifications are by far best in class: Dynamic Gain Adjustment 110dB (competitors offer 40dB) Slope Up to 100dB/usec* (competitors offer 12dB/usec to 40dB/usec) Number of Points 50 (competitors offer 10 to 20 points)*Depends on Filter Setting

EPOCH XT AWS D1.1 / D1.5

The EPOCH XT AWS D1.1 / D1.5 Software Option is intended to assist operators performing weld inspections according to AWS D1.1 / D1.5 regulations.

73

EPOCH XT AWS D1.1 / D1.5

While performing the inspection, the EPOCH provides the operator with the calculated D value (A-B-C=D) used to evaluate welds.

A (Indication Level): Automatically calculated in the EPOCH 4 for any indication echo less than 100% Full Screen Height. B (Reference Level): User entered at instrument calibration. C (Attenuation Factor): Automatically calculated based on the EPOCH Soundpath Calculator.

The EPOCH saves all data for A, B, C, and D for later review and inspection report generation.

74

AWS Activation

The AWS D1.1 / D1.5 Option is activated in the MEAS SETUP Menu under the Options TAB.

75

AWS Activation

After AWS D1.1 / D1.5 is turned ON, the operator must capture a reference echo. This is shown in the screenshots below:

76

AWS Measurement

Once the reference echo has been captured the EPOCH XT will automatically provide a D rating for a non-saturated gated reflector. This is shown below:

The instrument will store all setup parameters, measurements, the A-Scan, as well as the values for A, B, C, and D from the AWS formula. 77

EPOCH XT Accessories

Batteries When placing an order you will be able to specify NiMH or Lithium Ion battery. The instrument and its external charger can charge both battery types.

C-Cells All EPOCH XTs have the ability to use Alkaline C-Cell batteries. Every instrument will ship with a foam block to help hold C-Cell batteries in place before the battery door is closed.

116


External Charger The EPOCH XT has an external smart battery charger available as an option. This battery charger has the ability to calibrate these batteries periodically greatly extending their useful life. Sun Shade The sun shade casts a shadow on the EPXT display. Outdoor conditions might require this accessory for better visibility. The sun shade grips onto the XXX with or without the Rubber Boot.

117


Hardware I/O This option should be ordered when the instrument is ordered because an upgrade requires the instrument to be sent to a service center. Hardware I/O cable We are designing a 16 pin LEMO cable to match the instruments I/O port. The cable will not have a connection on the non-instrument end. This cable will be supplied with an output diagram for integration. Rubber Boot The rubber boot features an removable plastic window that protects the instruments permanently bonded display window.

118


Chest Harness The EPOCH 4 chest harness is available for use with the EPOCH XT. Since D-Rings are case mounted the Rubber Boot is not required for chest harness use. Transport Case The EPOCH XT Transport case is being designed to allow more storage of transducers, extra batteries, cables, couplant, etc.
