Page 76: Pulse Repetition Frequency (Prf)
6.2.6 Pulse Repetition Frequency (PRF) The EPOCH 6LT allows you to manually adjust the PRF from 10 Hz to 2000 Hz in 50 Hz (coarse) or 10 Hz (fine) increments. The instrument has an Auto-PRF mode to automatically adjust the PRF based on screen range.
Page 77: Adjusting The Receiver
The EPOCH 6LT is a single-shot instrument. This means that the instrument acquires, measures, and draws the complete A-scan with each pulse rather than using multiple acquisitions to construct a full waveform. The measurement rate in the EPOCH 6LT is always equal to the PRF rate unless you are using a multiplexer.
Page 78: Digital Receiver Filters
6.3.1 Digital Receiver Filters The EPOCH 6LT has a total instrument bandwidth of 0.2–26.5 MHz at −3 dB. The instrument offers 8 standard fixed digital filters designed to improve the signal-to-noise ratio by filtering out unwanted high and/or low frequency noise.
Page 79: Waveform Rectification
6.3.2 Waveform Rectification The EPOCH 6LT can operate in one of four different rectification modes: Full, Half+, Half-, or RF (unrectified). NOTE RF mode is not active while operating in special software feature modes, such as DAC mode or Peak Memory.

Page 85: Gate Measurement Modes
(see “Zooming in on a Gate” on page 81 for details). Gate Measurement Modes The EPOCH 6LT ultrasonic flaw detector’s two gates provide measurements of a gated indication based on one of four possible measurements modes. You can select the measurement mode of a gate in the Gate1 or Gate2 dialog box (see Figure 7-4 on page 75).
Page 86: Figure 7-5 Gate Trigger Indicator In Edge (Left) And Peak (Right) Modes
DMTA-10084-01EN, Rev. 2, November 2018 When a measurement is in progress using one of the measurement gates, a small triangle appears on the gate to indicate from which echo/point the measurement is being acquired (see Figure 7-5 on page 76 and Figure 7-6 on page 77). This triangle is called the gate trigger indicator.
Page 87: Figure 7-6 Gate Trigger Indicator In 1Stpeak (Left) And J-Flank (Right) Modes
DMTA-10084-01EN, Rev. 2, November 2018 1stPeak Acquires measurement readings based on the position of the first peak to break the threshold of the gate within the gated region (see Figure 7-6 on page 77). J-Flank Acquires thickness measurement readings based on the position of the first crossing point of a gated signal and amplitude measurement readings from the highest peak of the first echo in the gated region (see Figure 7-6 on page 77).
Page 88: Viewing Measurement Readings
NOTE The EPOCH 6LT does not acquire measurement readings unless the indication of interest is within a gated region of the screen. You should be careful to adjust the Start, Width, and Level of a measurement gate so that only the indication of interest falls within the gated region, as per the measurement mode definitions above.
Page 89: Gate Tracking And Echo-To-Echo Measurements
DMTA-10084-01EN, Rev. 2, November 2018 Gate Tracking and Echo-to-Echo Measurements The gate tracking feature enables you to make echo-to-echo measurements whenever this feature is required by an application. Echo-to-echo measurements can be made between gate 2 and gate 1. Gate tracking maintains a constant separation between the position of the indication in the first gate and the start position of the second gate.

Echo-to-echo flag Figure 7-7 Echo-to-echo measurement example Time-of-Flight Mode The EPOCH 6LT is capable of displaying time-of-flight (TOF) sound path data for a gated indication. Time-of-flight is the location of the reflector in terms of microseconds. The time-of-flight mode does not divide the measurement reading value by two. The entire time-of-flight through the test piece in both directions is displayed.
Page 91: Zooming In On A Gate
Figure 7-8 Time-of-flight measurement Zooming in on a Gate The EPOCH 6LT can quickly zoom in the screen range to provide fine resolution of a particular inspection zone. When the zoom is activated, the instrument automatically brings the point that corresponds to the gate start to the left side of the screen and adjusts the displayed range to match the gate width.
Page 92: Gate Alarms
In unrectified (RF) mode, gate alarms can be used in positive, negative, or dual gate modes. By default, when an alarm condition is triggered, the EPOCH 6LT emits an audible beep. The instrument also illuminates the red indicator, above the display window, corresponding to the gate with which the alarm has been triggered.

Page 99: Calibration
DMTA-10084-01EN, Rev. 2, November 2018 8. Calibration Calibrating the EPOCH 6LT is the process of adjusting the unit so that it measures accurately on a particular material, using a particular transducer at a particular temperature. In calibrating the instrument, you set the zero offset and velocity parameters. The zero offset (sometimes referred to as probe delay) is set to compensate for the dead time between the firing of the main pulse and the entry of the sound into the test piece.
Page 100 DMTA-10084-01EN, Rev. 2, November 2018 On the setup menu, select the UT icon ( ), and then press the Enter key to open the UT dialog box (see Figure 8-1 on page 91). Press the Enter key to select Range, and then turn the adjustment knob to set the range based on the sound path range within the selected calibration block.

Page 102: Calibration Modes
Straight Beam Modes Straight beam calibrations can be performed using one of two modes. For the purposes of the EPOCH 6LT calibration, straight beam refers to all zero-degree probes, including contact, dual, delay line, immersion, etc. The two straight beam calibration modes are as follows: •...
Page 103: Angle Beam Modes
For accurate measurements, you must first verify the refracted angle of the transducer, since the EPOCH 6LT calculates depth values based on sound path and known refracted angle. The shallow reflector depth allows for zero offset calibration, and the deep reflector depth allows for velocity calibration.
Page 104 NOTE If the EPOCH 6LT is set to work in metric units, the calibration process is exactly the same, except the entries are in millimeters rather than inches. To calibrate using a straight beam transducer Couple the transducer to the 0.200 in.

Page 175: Figure 11-11 Standard Dac With 6 Db Scanning Gain
To quickly find and identify potential defects, it is commonly required by code to increase the gain (scanning gain) on the EPOCH 6LT from the reference (calibration) gain for scanning purposes. However, after a potential defect is identified, this gain is usually removed to view the reflector at Ref gain level, set at calibration.
Page 176: Figure 11-12 Standard Dac With Scanning Gain Off
DMTA-10084-01EN, Rev. 2, November 2018 Select the Off button to turn the scanning gain off completely. Figure 11-12 on page 166 shows a Standard DAC setup with 6 dB of scanning gain added. Figure 11-12 Standard DAC with scanning gain off When reference correction is active, the digital comparison between a captured reflector and the DAC curve is accurate even with the scanning gain applied to the inspection, provided that the gated echo is not saturated.

Page 178: Figure 11-14 Dac Curves With Adjusted Gain
The coupling conditions on the test surface can often cause signal loss after calibrating a DAC curve, which results in inaccurate comparisons of the test reflectors with the calibrated DAC curve. The EPOCH 6LT can be easily adjusted for this potential difference by adding transfer correction to the calibrated base gain after completing the DAC curve setup.

20 % FSH. Therefore, to inspect beyond a certain depth/sound path time within a part, it is necessary to raise the gain of both the live A-scan and the DGS/AVG curve to continue the inspection. This is accomplished on the EPOCH 6LT using the DGS/AVG curve-adjustment gain.
Page 189: Registration Level Adjustment
This is usually equal to the critical flaw size for the application. The EPOCH 6LT allows you to adjust this registration level during a live inspection.
Page 190: Relative Attenuation Measurement
This allows the EPOCH 6LT to plot the attenuation curve (in steel) for a particular reflector size without having to acquire individual data points, as is required in a DAC/TCG setup.
