Page 24: Setting The Approximate Length
In order to utilize the AUTO SET feature of the MAX II, when measuring reference lengths, the MAX II has to know where to start looking for the detection. We can accomplish this by entering an approximate length into the gauge. The MAX II will automatically take the value entered and scan +/- 5% in both directions of the approximate length for the detection signal.

Page 29 Dakota Ultrasonics Important Note (recap): Always be sure to place the transducer in the same exact location if it will be removed in between reference lengths and elongation measurements. This will eliminate any potential sound path error caused by moving the transducer to a completely different location on the bolt, thus causing potentially erroneous measurements.
Page 30: Chapter Four Keyboard, Menu, & Connector Reference
CHAPTER FOUR KEYBOARD, MENU, & CONNECTOR REFERENCE 4.1 Menu Key (Operation & Sub Menus) The Menu key activates the primary menu structure containing 11 menu tab groups.

There are three zero mode options available in the MAX II – FIXED, ONE POINT, TWO POINT and AUTO. Selecting the proper mode is dependent on the application requirements, but the most convenient mode of preference is - AUTO.
Page 33: Matl (Material) - Menu
LOAD FACTOR: The conversion factor from elongation to Load. This value is typically determined by performing a field calibration and running a regression or vector using the MAX II or utility software. Alternatively, the load factor can be determined using the bolt calculator in the utility software. However, if extreme GlobalTestSupply www.

Page 45: Chapter Five Theory Of Operation
While the concept is comparatively simple and ultrasonic measurement can produce astoundingly accurate results, the selection of the optimum bolt and transducer, and their coupling can be difficult. The MAX II minimizes these difficulties to the greatest extent possible:  The variable width pulser system can send the maximum amount of energy to the ultrasonic transducer, allowing the broadest possible range of transducers for a given application.
Page 46: Ultrasonic Waves
5.4 Measurement Modes In this section we will discuss the different measurements modes the MAX II is capable of operating in, the transducers required, and the reasons for using specific modes:...
Page 47 Dakota Ultrasonics Echo-Echo Mode (E-E) Multi echo mode that measures from the first to the second return echo, and blocks the initial pulse. This mode can slightly improve user transducer placement errors, coated fasteners, and coated fasteners with changes in temperature. Because two return echoes are required, generally not suitable for long fasteners applications.
Page 48: Chapter Six Bolt Preparation
6.1 Use of Ultrasonic Couplant Sonic energy at the frequency range used by the MAX II travels well through solid materials and most liquids. It does not travel well through air. This variable resistance to the passage of sonic energy is called sonic impedance.
Page 49 Dakota Ultrasonics Figure 1 Sound path in a good bolt Smooth, even surfaced bolt ends that seat the entire active surface of the transducer with minimum gap are required for accurate signal transmission. Bolt ends may need to be cleaned, ground, etc. to achieve the required surface.

Page 52: Chapter Seven Transducer Selection
CHAPTER SEVEN TRANSDUCER SELECTION 7.1 Selecting the Transducer Transducer selection is a very import part of getting the best results from the MAX II. The frequency and diameter of transducer should be carefully selected using the following information:  Select the largest diameter transducer that will seat completely on the end of the bolt.
Page 53: Chapter Eight Measuring System Zero (Calibration)
Data created using one MAX II, can send the data file to another operator for use in another MAX II, transducer (diameter or frequency), or cable (length or type). The MAX II offers a few selectable calibration options for flexibility based on preference, or the type of calibration standard used.

(not recommended for use with our triple path glass block). If valid signals cannot be acquired during the ‘auto set’ routine, the MAX II will report “can’t find stable echo”. Before eliminating this option altogether and using one of the manual options listed below, try relocating the transducer to various positions on the end of the calibration standard first.
Page 56 MAX II Bolt Tension Monitor Caution: A very small amount of “WATER”, or other non-intrusive fluid with a similar viscosity, should be used as the couplant between the transducer and calibration standard selected.

Page 74: Using A 'Set Aside' Bolt
The primary objective is to establish a zero, verify a zero value prior to measuring, and avoid measurement errors if the MAX II, transducer, or cable has been replaced. While this sounds like an economic way to go, the operator must keep in mind the lack of a calibration certificate, and the need to maintain possession of the bolt, either at the jobsite or in a storage facility for future measurements.

Page 76: Chapter Nine Temperature Compensation
CHAPTER NINE TEMPERATURE COMPENSATION 9.1 Purpose The temperature of a fastener affects the overall physical length, as well as the velocity of a fastener. As the temperature of a fastener increases, the ultrasonic length increases at a rate greater than the physical change in length. If the user intends to measure the same fastener at different time intervals over the service life of the bolt, temperature compensation is very important to produce accurate results.

Page 85: Stress Factor Calibration
Since the change in ultrasonic length is approximately 3 times the change in physical length, due to the change in velocity, a stress factor must be applied to correct the ultrasonic length in the MAX II. GlobalTestSupply www.
Page 86 Sonic Stress Factor is to be determined. NOTES:  The Dakota Ultrasonics MAX II must be calibrated, or zeroed, as described in the Zero Calibration procedure section Error! Reference source not found..  The Velocity Calibration should be performed prior to determining the Stress Factor.
Page 87 Note: The following steps assume that the user has performed the steps in the previous section and calibrated the velocity. Therefore, the velocity has been adjusted, approximate length already entered, and the MAX II is currently setup and ready to measure in elongation mode.

Rotate the transducer clockwise and counter clockwise applying a small amount of pressure to eliminate any excess couplant between the transducer and bolt.
Page 92: Chapter Eleven Load Measurment
The cross sectional area of the bolt is defined as the average area of a fastener under stress. This factor is only used in the MAX II’s calculation of load. It has no effect on stress or elongation, time, or strain, and is directly proportional to the load measured ultrasonically.
Page 93 Dakota Ultrasonics For bolts with complex geometry, the areas should be estimated by averaging each individual area and length. In the case of a hollow fastener, the area of the hole must be subtracted from the overall area. The area of a fastener with complex geometry can be estimated as follows: ...
Page 94: Calibrating Load Factor (Field Calibration)
The MAX II is equipped with a self- calibrating feature that uses a linear regression or vector equation to produce a best-fit line through the known loads, minimizing error.
Page 95: Performing A Field Calibration
Dakota Ultrasonics zero and produces only a load factor. Why are both options needed? In applications where a small amount of load is applied to the fastener, thus producing very little elongation, the regression option can potentially produce non-linear results. In cases such as these, a vector may sometimes produce better results as the offset is set at zero.
