Preface
Important Ultrasonic Testing Guidelines
Please read the information in this section before using your instrument. It is important that you understand and observe this information to
avoid any operator errors that might lead to false test results. Such false results could result in personal injuries or property damage.
Using Ultrasonic Test Equipment
This Operator’s Manual contains essential information on how to operate your test equipment. In addition, there are a number of factors that
affect the test results, but a description of all these factors is beyond the scope of this manual. The three most important factors for safe and
reliable ultrasonic inspection are:
• Operator training
• Knowledge of special technical test requirements and limits
• Choice of appropriate test equipment
xiv
DMS Go Operator’s Manual
Preface
Operator Training
The operation of an ultrasonic test device requires proper training in ultrasonic testing methods. Proper training comprises adequate
knowledge of:
• The theory of sound propagation
• The effects of sound velocity in the test material
• The behavior of the sound waves at interfaces between different materials
• The shape of the sound beam
• The influence of sound attenuation in the test object and the influence of the surface quality of the test object
Lack of such knowledge could lead to false test results with unforeseeable consequences. You can contact GEIT or NDT societies or
organizations in your country (DGZfP in Germany; ASNT in the USA) for information on opportunities for training on ultrasonic
instruments that use time-of-flight measurements.
Accurate measurement results require a constant sound velocity in the test object. Steel test objects have only slight variations in sound
velocity, thus affecting only high precision measurements. Test objects made of other materials (e.g., nonferrous metals or plastics) may
have larger sound velocity variations, which could adversely affect the accuracy of the measurements.
DMS Go Operator’s Manual
xv
Preface
Test Object Material Effects
If the material of the test object is not homogeneous, the sound waves may propagate at different velocities in different parts of the test
object. An average sound velocity should then be used for the range calibration. This is achieved by using a reference block with a sound
velocity equal to the average sound velocity of the test object.
If substantial sound velocity variations are expected, then the instrument calibration should be adjusted to the actual sound velocity values at
shorter time intervals. Failure to do so may lead to false readings.
Test Object Temperature Effects
The sound velocity also varies as a function of the temperature of the test object. This can cause appreciable errors in measurements if the
instrument has been calibrated with a reference block at one temperature, and the instrument is then used on a test object at a different
temperature. Such measurement errors can be avoided either by ensuring that the reference block and the test object are at the same
temperature, or by using a correction factor obtained from published tables.

Chapter 1. General Information
The DMS Go is a portable ultrasonic thickness gauge. In addition to its light-weight design, the DMS Go includes a clean and simple user
interface and a large, easy-to-read color WVGA (800x480) display. The instrument provides ultrasonic flaw detection and thickness
measurements., and can store scans, operating parameters, and reports. Before beginning to take measurements, however, the instrument
display, operating parameters, and data files must be configured by using the Configure, Probe & Cal, and DR menus. The following
specific topics are discussed in this chapter:
• Supplying power to the instrument
• Powering the instrument ON and OFF
• Using the keypad
• Using the display

Chapter 1. General Information
1.1 Supplying Power to the Instrument (cont.)
The DMS Go can be powered in either of two ways (see Figure 1 on page 2):
• A lithium-ion battery pack that is installed in a compartment on the rear of the case, or
• An external power adapter plugged into the connector on the side of the case
CAUTION!
Use only the GEIT supplied lithium-ion battery pack in this instrument, and charge only this battery pack in the
instrument or in the provided GEIT charger/adapter.
To remove the battery compartment cover, loosen the two 1/4-turn screws and then lift up on the slot between the screws. The standard
GEIT lithium-ion battery pack is designed to provide maximum operating life between chargings.
The approximate level of remaining battery life is shown on the display (see Figure 2 on page 5) by the battery icon, , and the
approximate “hours of charge” indication below the icon. When a fully-charged battery pack is installed, the icon will appear as “full,” and
the icon will begin to “empty” as the battery life is depleted. If you remove the battery pack, the rear side of the pack offers a button. There
you will find a button that illuminates up to 5 blue LEDs, each of them representing @20% of battery charge (on) or discharge (off). If you
see all 5 LEDs lit, it means you have a fully charged pack. When the battery indicator is down to one-quarter full, charge the battery pack as
soon as possible.
Note: The instrument automatically shuts OFF when the batteries are too weak for reliable operation. However, your settings are saved
and then restored when the instrument is turned back ON. When testing in remote locations, always carry a spare battery pack.

Chapter 1. General Information
1.1 Supplying Power to the Instrument (cont.)
When the AC adapter is connected to the instrument, the icon in the upper right corner of the display indicates the percentage of full-charge
of the battery pack. When removing the battery pack to install a charged spare, the instrument will automatically turn OFF if the AC adapter
is not connected to the instrument. However, if the adapter is connected, the instrument will remain ON while you change battery packs.
1.2 Powering the Instrument ON and OFF
To power the DMS Go ON or OFF, simply press the power button,
, on the side of the case (see Figure 1 on page 2). As soon as the
button press is recognized, you will hear the click of an internal relay. Then, after about 4 seconds, the display controller will be fully loaded
and the display will become visible.
1.3 Using the Keypad
The DMS Go is designed to provide the user quick access to all of the instrument's functions. Its easy-to-use menu system allows any
function to be accessed with a minimum of effort.

1.3.1 Joystick Functions
The effects of the joystick actions described on the previous page are as follows:
Joystick Center Press:
• A single press and release (
) allows users to toggle between normal and Portrait mode, or between the menu navigation and the DR
navigation (when a DR menu is open). It also activates or deactivates a parameter for adjustment, or allows a user to enter (in certain
functions) a highlighted alphanumeric character. A 2-second press-and-hold (
) confirms an entry.
Joystick Movement:
• Moving up/down (
) scrolls between the available function options for the highlighted menu.
• Moving left/right (
) allows you to navigate to a menu. Once you have selected an option, it opens a menu option or adjusts the value
of a selected parameter. (In the DR Properties option, you can also navigate in the submenu.) When you push the joystick slightly,
numerical values change in small increments. Pushing the joystick to the extreme right or left will cause values to change rapidly or in
larger increments.

To remove the SD card from its slot, proceed as follows:
1. Access the SD card slot by pushing on the cover in the direction of the arrow and lifting the hinged cover.
2. Press down of the SD card with your finger and then remove your finger quickly. The SD card will be partially ejected, and you can
then grasp it by the edge and slide it completely out of the slot.
1.6.2 Inserting the SD Card
To insert the SD card into its slot, proceed as follows:
CAUTION!
Do not force the SD card into the slot if you feel significant resistance. If the card does not enter the slot freely, it is
probably oriented incorrectly.
1. Access the SD card slot by pushing on the cover in the direction of the arrow and lifting the hinged cover.
2. Orient the SD card so that the label side faces the rear of the instrument and the blank side with the row of gold-colored electrical
contacts faces the display side of the instrument. The edge of the card with the row of gold-colored electrical contacts must enter the
slot first.
3. Slide the card fully into the slot and push gently until the card seats into its socket. Then, close the SD card slot cover.

1.6.3 Connecting the USB Port
The connector closest to the hinge of the top compartment cover (see Figure 6 on page 16) is a Mini USB port. If you use a standard USB
cable to connect the DMS Go to a PC (no special drivers are required), the installed SD card will be added to the list of active drives on the
PC. You can then perform all normal drive activities, such as copying and deleting files, on the DMS Go SD card.
Important:
18
While the DMS Go is connected to a PC via the USB port, the instrument will not accept any user input from the keypad.
Normal operation resumes as soon as the USB cable is disconnected.
DMS Go Operator’s Manual
Chapter 1. General Information
1.6.4 Connecting the I/O Port
The connector furthest from the hinge of the top compartment cover (see Figure 6 on page 16) is an I/O port. This port serves a dual role:
• Serial port pins - these are used strictly for factory service diagnostics.
• Sync & Alarm pins - these signals are accessible to the user via a special optional cable.
To use this connector you must order the optional DMS Go cable, which is available as P/N 022-510-032. The pin designations for
connecting the open end of this cable are listed in Table 2 below:

Selecting a Rectification Mode (CONFIG-RECTIFY)
Rectification effects the orientation of the A-scan on the display screen. The A-scan represents the sound pulse (i.e., echo) that is returned to
the instrument from the material being tested. The series of echoes looks like the Radio Frequency (RF) signal shown in Figure 15 below.
Note that the RF signal has both a negative component below the axis and a positive component above the axis. In RF mode, Gate A and
Gate B can be positioned either above or below the axis, to be triggered by either a positive-heading echo or a negative-heading echo. The
rectification mode is normally automatically set up by the probe selection. Most GEIT thickness gauge probes are designed to be used in
negative rectification.

Chapter 2. Instrument Setup
2.3.2h
Selecting a Rectification Mode (CONFIG-RECTIFY) (cont.)
• Positive Halfwave Rectification means that only the upper (i.e. positive) half of the RF signal is displayed.
• Negative Half wave Rectification means that only the lower (i.e. negative) half of the RF signal is displayed (see Figure 15 on page 41).
Note that although only the negative half of the RF signal is displayed, it is shown in the same orientation as a positive component to
simplify viewing.
• Full-Wave Rectification combines the positive- and negative-rectified signals together, and displays both of them in a positive
orientation (see Figure 15 on page 41).
• RF means no rectification.
The rectification determines the cycle in which the zero crossing measurement is made. Under ordinary circumstances, GE recommends not
changing this parameter. It is only necessary to change the rectification mode for special probes or special applications.If necessary, use the
procedure on the next page to select a rectification mode.

Follow the instructions in this section to install a probe on your DMS Go.
2.4.1 Connecting the Probe
Receive
Probe
When connecting a probe to the instrument, the following steps must be taken:
• Properly complete the physical connection of the probe to the instrument.
• Properly configure the instrument to work with the connected probe.
The DMS Go accepts either a single-element probe or a dual-element probe.
A single element probe has only one ultrasound crystal. It acts first like a
loudspeaker, converting the electronic pulse into a mechanical ultrasound pulse, then
the same crystal acts at the same time like a microphone, receiving all the echoes,
converting these back into electronic pulses.

2.4.1 Connecting the Probe (cont.)
A dual element probe has the loudspeaker separated from the microphone. Identify these probes simply by the number of LEMO (or other
type of) connectors: one for a single, two for a dual.
To install a single-element probe, connect the probe cable to either of the two ports on the side of the instrument (see Figure 20 on the
previous page). When a dual-element probe is connected to the instrument, the key ensures proper orientation of the transmit and receive
connectors.

) to select the function titled TG MODE, and then to select the mode. Six options are available:
• S-IP — This mode indicates that a single-element type transducer is connected to the DMS Go. It starts ultrasonic detection from an
artificial point relative to the pulser firing (IP, initial pulse, or “T0”) and ends with the last zero crossing before the first detected
flank crossing in gate-A. The corresponding TOF is compensated by the probe zero offset (P-delay), calculated automatically
during the calibration process. The DMS Go calculates and displays a thickness result value from the acquired data. It is used with a
single-element probe to test thickness in non-coated materials, especially those with smooth, parallel surfaces.
• S-PEAK — This mode indicates that a single-element type transducer is connected to the DMS Go. It starts ultrasonic detection from
the last zero crossing before the peak in gate A and ends with the last zero crossing before the peak echo in gate-B. The DMS Go
calculates and displays a thickness result value from the acquired data. It is used with a single-element probe to test thickness in
coated materials, especially those with smooth, parallel surfaces.

crossing in gate-B. The DMS Go calculates and displays a thickness result value from the acquired data. The mode is used with a
single-element probe to test thickness in COATED materials, especially those with smooth, parallel surfaces.
• DUAL — This mode indicates that a dual-element type transducer is connected to the DMS Go. It starts ultrasonic detection from an
artificial point relative to the pulser firing (IP, initial pulse, or “T0”) and ends with the last zero crossing before the first detected
flank in gate-A. The corresponding TOF is compensated by the probe zero offset (P-delay), calculated automatically during the
calibration process. The DMS Go calculates and displays a thickness result value from the acquired data. This mode is used with a
dual-element probe to test corrosion thickness in non-coated materials, especially on curved and irregular backwall surfaces.
• DUAL-MULTI — This mode is available when a dual-element type transducer is connected to the DMS Go. It starts ultrasonic
detection from the last zero crossing before a peak echo detected in gate-A and ends with the last zero crossing before a peak echo in
gate-B. The DMS Go calculates and displays a thickness result value from the acquired data. This mode is used with a dual-element
probe to test thickness in coated materials.
• TOP-COAT—When used with a special TopCOAT probe, this mode tests thickness in coated materials. It is especially well suited to
curved and irregular (pitted) backwall surfaces. (Optional)

2.5 Calibration
Calibration of the DMS Go requires the use of a calibrated standard. This standard must be made of the same material as the test piece.The
calibration procedure varies, depending on whether you have selected 1 or 2 points in the THK CAL option. The choice of 1 or 2-point
calibration depends on your test blocks:
• 1 Point involves use of a single test block, for which you enter or verify the thickness; both gates appear, and measure the distance
between the first and second backwall echoes (BWEs). The DMS Go also calculates and sets sound velocity and probe delay.
Note: The number of gates (1 or 2) is independent of the CAL mode, but is determined by the measurement mode (1 gate for dual, 2 gates
for dual-multi). You can perform 1-point calibration with one gate from the start to first backwall.
• 2 Point involves use of two blocks, or a single block with two steps (low-cal and high-cal). A user enters or verifies first the lower step
block, then the higher step block.
One-point calibration requires using the Probe Zero function; however, zeroing is unnecessary in 2-point calibration.

Setting the Probe Zero (PROBE & CAL - ZERO)
TOF values that are started from an artificial point relative to the pulser firing (the initial pulse, IP, or “T0”), must be compensated by a
probe zero offset value to remove the transit time due to the artificial starting position and probe delay lines. This value also allows
adjustment for uneven probe wear and variations in delay lines.
Note: ZERO is not available when the DETECT MODE parameter specifies a gate-to-gate and multi-echo type measurement, or when the
THICKNESS CAL parameter is set to 2-point mode.

) to select the function titled ZERO, and then to select the zero method. Six options are available:
• Manual — This zero method uses the instrument reference block of known thickness and sound velocity to determine the probe zero
offset value for the connected transducer. It is applicable to both single and dual-element contact type transducers, and works with
critical coupling conditions or rough surfaces. See “Setting the Zero Block Configuration” on page 37 for information on how to
enter thickness and velocity of the zero block.
• Auto — This zero method automatically determines the probe zero offset value while the transducer is actively coupled to the
material being tested. Zero is taken from the interface echo after the probe was coupled, and then takes the backwall echo. It requires
good coupling conditions, and multiple data acquisitions to determine the TOF to the material interface (the point at which sound
enters the material) and the TOF to material backwall (the point at which sound reflects from the backside of the material). Since it
performs zeroing every time a measurement is taken, it continuously adjusts for temperature changes and delay wear.

Chapter 2. Instrument Setup
2.5.4 Adjusting Temperature Compensation (PROBE & CAL - TEMP COMP)
Temperature variations change the sound velocity of materials and transducer delay lines and, therefore calibrations. All calibrations should
be performed onsite, and with calibration blocks at the same temperature as the test piece, to minimize errors due to temperature variations.
When it is not possible to heat the calibration block, the use of a temperature compensation formula can be used to calculate the test piece
thickness back to ambient temperature.
Temperature Compensation: As the temperature of a test object increases, the ultrasonic velocity of the material will slightly decrease.
When this occurs, the wall thickness will read thicker than the actual temperature when measured at ambient. To compensate for this factor,
the DMS Go has the ability to calculate a compensated thickness value based upon the inputted test piece temperature and a compensation
factor.
1.
In the MAIN menu, scroll to the PROBE & CAL submenu using the joystick (
2.
Use the joystick to ENABLE or DISABLE temperature compensation. If you ENABLE temperature compensation, three other functions
appear:
).
• CAL TEMP - The temperature of the calibration block (typically ambient temperature).
• CUR TEMP - The current temperature of the material.
• TEMP COEF (Temperature Coefficient) - The change in material velocity per degree, adjusted from a user table. (A typical value for
carbon steel is -0.0002 in/us/°F or -0.###mm/m/C). The value input should be obtained from the company level III UT manager or
corporate NDT guidelines.

4.1.1
Setting up Data Measurements
Positioning Gate A and Gate B
Setting the position and the characteristics of Gate A and Gate B is the first step in configuring the instrument for material thickness
measurements. Use the procedures in this section to set the vertical and horizontal position of Gate A and Gate B. Remember that gate
position has the following effects on instrument performance:
• A-Scan echoes on the right side of the display screen represent features that occur at a greater depth from the test-material surface than
those on the left side of the display screen. Therefore, moving a gate to the right means that the gate is evaluating a deeper portion of the
test material.
• A wider gate setting means that the gate is evaluating a thicker portion of the test material.
• Increasing the vertical height, called the threshold, of a gate means that only reflected signals of sufficiently large amplitude will cross
the gate.
Each probe selected has default gate settings which should work for most applications. If the echoes are not being properly measured, the
user can adjust the gating to ensure the DMS Go is measuring the proper echoes. To configure the gate parameters, proceed to the
appropriate section:

Adjusting the Gate Width (GATE - GATE A WIDTH or GATE B WIDTH)
Adjusting the A-gate width may be necessary in multi-echo modes because the returning sound pulse (backwall echo) may be too low in
amplitude to trigger a measurement reading. Adjusting the B-gate width reduces or increases the width of the B-gate to control which signal
crosses the B-gate and triggers a thickness measurement.

4.1.2
Selecting the Measurement Method (MEASURE - MODE)
The DMS Go can perform thickness measurement and corrosion monitoring in five modes:
• A-Scan- Display in which the echo amplitude is shown in the y-axis and the transmit time (also shown without echoes) and the pulse
travel time is shown in the x-axis. It provides a graphical display of the echoes used to measure thickness.
• B-Scan - Two-dimensional graph in which travel time is shown in the vertical axis and transducer movement in the horizontal axis.
If you select B-Scan, the Measure menu has two additional options:
• TIMEOUT - The time that elapses, once a probe is uncoupled from the DMS Go, before the B-scan stops. (During the timeout period,
the battery icon in the upper right corner fills with yellow.) The B-scan mode will allow you to map the thickness profile of the
material being tested over a period of time. The thickness mapping procedure may be briefly interrupted during this time period. The
maximum length of this interruption of data collection is controlled by the TIMEOUT feature, which can be set from 0 to 15 seconds.
• TIME — The duration of a B-scan (from 7 to 30 sec).
Use the joystick to adjust these parameters.
• Min/Max - Display of minimum and maximum values. This mode relies on a sequence of readings. On the left of the screen, it always
shows the minimum value of the sequence; on the right, it shows the maximum value. The large reading in the center is the current
value. If the probe is uncoupled for several seconds, the sequence is terminated. When you resume in Min/Max, the DMS Go starts a
new sequence. This mode aids in determining the stability of your actual reading(s) or the overall deviation of the thickness in your test
piece while scanning.

Selecting the Measurement Method (MEASURE - MODE) (cont.)
• Diff - Display of differential values. DIFF shows the difference from a NOMINAL value (located just below that function) as an absolute
value or as a percentage related to NOMINAL. Positive means “More than” Negative means “Less than” NOMINAL absolute or
relative in percentage. For example, for a NOMINAL thickness of 5.00mm for a tube wall, then a 4.50mm is indicated as -0.50mm, and
10% delta value. The delta symbol means Difference.
Note: Use the F3 and F4 keys to enter the NOMINAL option, and to enter values in increments of 10. Use the joystick to enter values in
increments of 1.
• Thickness - The thickness currently being measured (if the probe is coupled) or the last valid thickness value measured. The displayed
numerals will appear “solid” whenever the probe is coupled and “hollow”, or as a series of dashes (- - -), when uncoupled. The Last
Reading function sets the appearance when uncoupled.

Setting up a Dual Element Transducer (MEASURE - DUAL MULTI)
Note: This function does not appear if a single-element probe is connected.
The Dual Multi mode is available when a dual-element type transducer is connected to the DMS Go. It starts ultrasonic detection from the
zero crossing before a peak echo detected in gate-A and ends with the zero crossing before a peak echo in gate-B. The DMS Go calculates
and displays a thickness result value from the acquired data. This mode, sometimes called “Thru-Coating,” is always used with a
dual-element probe to test thickness through painted or coated materials. From the base material, the probe measures between two backwall
echoes. If you have attached a dual element transducer to the DMS Go, you should set this option to ON.

Setting the MAX GAIN MODE (MEASURE - MAX GAIN MODE)
The DMS Go always operates in Automatic Gain Control (AGC) mode: the gain is adjusted automatically by the instrument to get the echo
in the gate 4dB above the gate threshold. MAX GAIN MODE is used to select the maximum gain used by the AGC process:
• HIGH: the max gain is limited to a preset (different for each probe) high gain value (suitable for attenuative material like Stainless Steel)
• LOW: the max gain is limited to a preset (different for each probe) low gain value (suitable for less-attenuative material like Aluminum)
• AUTO: the instrument select the HIGH or LOW preset value automatically based on material velocity (the switch between HIGH and
LOW is at 6248400 mm/s = 246000 in/s to differentiate between steel and aluminum)
• MANUAL: the max gain is limited to the value set in “max gain” field (discussed on the next page).

Chapter 5. Using Parameter Files
The current DMS Go settings, which include most of the functional settings, can be stored as a parameter file. When a stored parameter file
is later recalled, all active function settings are modified to match those contained in the file. After a data set is loaded, the newly active
functional settings may then be modified if desired, and saved for later use. The PARAM menu allows users to select, save and re-load up to
twenty thickness gage parameter sets with corresponding A-scan images. When a parameter set is saved by selecting SAVE P-SET, the
settings of all of the parameters (except the user preferences listed below) are retained. You can then apply this set of parameter settings
(usually associated with specific applications such as tanks or cooling tubes) to a data file by selecting LOAD P-SET.
When an existing P-SET is loaded or applied to a new data file, the current instrument settings are automatically replaced by the stored
settings and the stored A-scan image is displayed. These settings can then be adjusted as required. The saved P-SET can’t be changed. If you
wish to modify an existing P-SET, first make the changes, delete the existing P-SET, as described below, and save the new parameter
settings using the same P-SET name. This feature provides the following two major benefits:
1.
Storing and recalling calibration setups saves time, ensures consistent data, and minimizes calibration errors. Transferring setups to and
from a computer also saves time and allows identical setups to be stored in multiple instruments.
2.
A-scan images and parameter sets associated with specific applications, such as pitted or thin wall conditions, can be saved in a
consistent format and later recalled, printed, or transferred to a computer for documentation and analysis.
All settings (including current A-Scan) are saved except the user preferences: language, radix, brightness, screen color, orientation, zero
block and reference block.

Using Existing Data Recorder Files (DR - PROPERTIES) (cont.)
Once thickness measurements are stored in data files, users can quickly locate specific points within a file and locate specific values for all
file parameters. For instance, users can pinpoint a value in a specific grid location, check maximum and minimum values, and t. This section
describes ways you can use the Properties submenu to examine and edit your files.
6.3.1
Moving to a Specific Data Point (DR-PROPERTIES-RECORD)
Note: To use this function, you must have created a 2-dimension file having ROWs and COLumns. A LINEAR file has LOCATIONS only!
Note: The described features are available in VIEW mode LIST only.
In the RECORD submenu, you can directly access the specific row and column location of the currently active file.
1.
Be sure the RECORD submenu is highlighted in the PROPERTIES function (see Figure 31 on page 112).

114
DMS Go Operator’s Manual
Chapter 6. Working with Recorded Data
6.3.2
Modifying Data Entry (DR-PROPERTIES-RECORD)
In the RECORD submenu, you can also modify the way in which the DMS Go enters data into the file.When operating in the MEASURE
menu, a user stores thickness measurement in the active data file location by pressing F 2 (SEND) . Then, the instrument typically advances
automatically, making the next point in the data file active. However, you can modify the AUTO-ADVANCE feature to suit specific
measurement applications. For instance, when recording measurements into a large grid type file, the physical measurement site may dictate
that it’s best to advance by column. Thus, the active data point would automatically move horizontally across the file window, and all the
way through the last column before moving down to the next point or row in the file.
Once the AUTO-ADVANCE feature has moved through a column of data, it will then move on the next column or point, and move through
all of the rows in that column of data. If AUTO REVERSE is turned ON, when data is recorded in the last row, the next position will be at
the last position of the next column. If AUTO REVERSE is OFF (the default position), the next position will be at the first position of the
next column.
To change how the DMS Go enters data:
1.
From the RECORD submenu, use the joystick to scroll to SEND FUNCTION. You can choose from three selections: Thickness,
Thickness + ASCAN, and Thickness/Thickness + ASCAN.
2.
Scroll to ADVANCE TIME. You can select a time at which the file will automatically advance from 0.0 to 3.0 sec (in 0.5 sec increments).
3.
Scroll to 1st ADVANCE BY. Depending on your file type, the selections can include Row, Column, Location, Point, and Elevation.Set
the first advance value to the file component you wish to auto-advance through first.
4.
Scroll to 1st ADVANCE DIR.The options are the FORWARD and BACKWARD directions, which determine whether the auto-advance
moves in the direction of increasing (+) or decreasing (-). Set the desired direction.

6.3.3
Viewing File Statistics (DR-PROPERTIES-STATS)
In the STAT submenu, you can evaluate a data file’s contents to identify overall trends. The DMS Go automatically compiles and calculates
the following statistical data related to each data file:
• Number of readings
• Number of empty points
• Number of obstructed points
• Minimum thickness reading stored
• Number of data points at the minimum thickness level
• Number of thickness points below the min-thickness limit
• Maximum thickness reading stored

• Number of data points at the maximum thickness level
• Number of thickness points above the max-thickness limit
• Number of points with A-scans attached
• Number of points with B-scans attached
• Number of points with Micro-Grids attached
• The range, mean range, and standard deviation of the data contained in the data file (empty and obstructed points are excluded from
these calculations.)
To view the statistical properties listed above, from the PROPERTIES menu, use the joystick to highlight the STATS submenu. You can then
scroll to the required statistic. In addition, you can press F2 to TAG a specific field to perform a search. For example you can tag “EMPTY
PNTS” . Then you can press F3 (SEARCH) and the DMS Go will return in the DR section all the empty points. This function aids users to

B.5 Boiler File
The boiler file is a Data file format with three structure elements (ELEVATION, TUBE, and POINT); especially for inspecting boilers and
other structures with two identifying levels.
Figure 37: Boiler File Structure
Each elevation must be given a name by the user. Each elevation will have the same number of points as set by the user when the file is
created.

B.5.1 Boiler File Flexibility
• Free choice of first tube to be tested
• Free choice of distance with “skipping” of tubes
Note: If you are measuring ribbed tubes and recording in a Boiler file, you can automatically insert “OBST” into a designated series of C
(center) positions. Set up the file with the “Points on Tube” option set to “L, C, R” (left, center, right). At a specific center (c) data
location, press F3 (OBST). A screen appears similar to Figure 38 below.Enter the end tube number for the last center location to
contain OBST. The DMS Go then inserts OBST into the designated center locations The user may then attach a “RIBBED” comment
to all obstructed positions
.

Appendix C. Environmental Compliance
Appendix C. Environmental Compliance
This appendix contains information on the following topics:
• WEEE Directive (see Section C.1 on page 152)
• Battery disposal (see Section C.2 on page 153)
DMS Go Operator’s Manual

Appendix C. Environmental Compliance
C.1 Waste Electrical and Electronic Equipment (WEEE) Directive
GE Sensing & Inspection Technologies is an active participant in Europe’s Waste Electrical and Electronic Equipment (WEEE) take-back
initiative, directive 2002/96/EC.
The equipment that you bought has required the extraction and use of natural resources for its production. It may
contain hazardous substances that could impact health and the environment.
In order to avoid the dissemination of those substances in our environment and to diminish the pressure on the natural
resources, we encourage you to use the appropriate take-back systems. Those systems will reuse or recycle most of
the materials of your end life equipment in a sound way.
The crossed-out wheeled bin symbol invites you to use those systems.
If you need more information on the collection, reuse and recycling systems, please contact your local or regional waste administration.
Visit www.ge.com/inspectiontechnologies for take-back instructions and more information about this initiative.

DMS Go Operator’s Manual
Appendix C. Environmental Compliance
C.2 Battery Disposal
This product contains a battery that cannot be disposed of as unsorted municipal waste in the European Union. See
the product documentation for specific battery information. The battery is marked with this symbol, which may
include lettering to indicate cadmium (Cd), lead (Pb), or mercury (Hg). For proper recycling return the battery to your
supplier or to a designated collection point.
C.2.1 What do the Markings Mean?
Batteries and accumulators must be marked (either on the battery or accumulator or on its packaging, depending on size) with the
separate collection symbol. In addition, the marking must include the chemical symbols of specific levels of toxic metals as follows:
• Cadmium (Cd) over 0.002%
• Lead (Pb) over 0.004%
• Mercury (Hg) over 0.0005%
DMS Go Operator’s Manual
153
Appendix C. Environmental Compliance
C.2.2 The Risks and Your Role in Reducing Them
Your participation is an important part of the effort to minimize the impact of batteries and accumulators on the environment and on human
health. For proper recycling you can return this product or the batteries or accumulators it contains to your supplier or to a designated
collection point.
Some batteries or accumulators contain toxic metals that pose serious risks to human health and to the environment. When required, the
product marking includes chemical symbols that indicate the presence toxic metals: Pb for lead, Hg for mercury, and Cd for cadmium.
• Cadmium poisoning can result in cancer of the lungs and prostate gland. Chronic effects include kidney damage, pulmonary
emphysema, and bone diseases such as osteomalcia and osteoporosis. Cadmium may also cause anemia, discoloration of the teeth, and
loss of smell (anosmia).
• Lead is poisonous in all forms. It accumulates in the body, so each exposure is significant. Ingestion and inhalation of lead can cause
severe damage to human health. Risks include brain damage, convulsions, malnutrition, and sterility.
• Mercury creates hazardous vapors at room temperature. Exposure to high concentrations of mercury vapor can cause a variety of severe
symptoms. Risks include chronic inflammation of mouth and gums, personality change, nervousness, fever, and rashes.
