TG MODE

When unit is turned on, it

goes to the TG ModeConfirms probe andmeasurement modes in one

view.

Probe Selection - Dialog Probe

Dialog Probe : Automatically

selected by the instrument.Can not change selection.

Sets up Gain, Gates, Mode

and other probe selectionitems.

Measurement Mode

Select Measurement Mode

for application

Non-Coated Material =DUAL

Coated Material = DUAL-MULTI


6/34



DUAL Mode

Measurement is made to

the 1st backwall echo.

Used for makingmeasurements when nocoatings are present on thetest object

Carrot shows echo

being measured


7/34



DUAL-MULTI Mode

Measurement is made from

the 1st backwall echo to the2nd backwall echo

Requires 2 gate operation.

Used for measuringmaterials with coatings areon the surface

Carrots shows echoes

being measured


8/34



Probe Zero Mode

Probe zero measures thedelay times in the probe so

the instrument knows whento start measuring the testmaterial.

AUTO - automatically setszero (default)

MANUAL - User has topress PRB ZERO key tozero the probe.

Thickness Calibration Options - 1 Point

Calibrate to a known

thickness sample or cal.Block

DMS 2 performs Zero

Couple to sample

Adjust thickness and press

SEND


10/34



Thickness Calibration Options - 2 Point

Calibration on a Thin andThick calibration Block

Set THKCAL to 2-PT

Adjust Low BlockThickness

Measure and press SEND

Adjust High Block

Thickness

Measure and press SEND


11/34



2 Point Calib. Memory

DMS 2 remembers thethin

andthick

values so youDONTadjust them everytime you calibrate

Simply press CAL, and theSEND key twice tocomplete a 2-pt Calibration

Remembered

Velocity Calibration

Adjust velocity to knowvalue to calibrate system

Alarm Menu

Set and turn on both Min.

and Max. alarmsIf thickness values exceedthe limits, the red LED will

light, < or > icon shows thealarm on the display.

B-Scan Operation

Before Starting B-Scan

Set Range

Set Sweep Time

Set Time-Out

Set T-Min. Value (same asalarm T-Min.)


17/34



B-Scan Operation

During the scan

Range, Time, T-Min itemsare not shown

No thickness display isshown


18/34



B-Scan Operation

At the end of the scan

Minimum value isdisplayed

Range, Time, T-Min valuesare shown (but notchangeable)

CLEAR function is active -Pressing CLEAR will erasethe B-Scan and start the

process over.


19/34



Parameter Sets

ONLY the DMS 2 allows

Parameter Sets to be savedfor both single AND dualelement probes.

Complete calibrationincluding Velocity settings.


20/34



Parameter Sets

Using parameter sets allows for saving and

recalling special set-ups.Only a simple calibration check may be required

after recalling a Parameter set. Significant timesaver!!!


21/34



TEST MODE

TEST key always takes you

to the TEST ModeActs like home key.

Where MENU you are inpressing the TEST key willtake you out and to theTEST menu.


22/34



MIN-CAP saves time

Use the DMS 2 Min-Cap mode to always get

the minimum thickness.Fast 32Hz measurement rate.

Time Out mode allows re-couple of probe tocomplete scanning (no need to start over).


23/34



Min Cap Mode

While Scanning, the

minimum value measured isdisplayed in the black box.

The live value is in big digits


24/34



Time Out Bar

If you un-couple during a

Min-Cap scan, the time outbar indicated how muchtime is left that you can re-couple to continue the scan.


25/34



Min-Cap Completed

When the time out has

completed, the DMS 2 willdisplay the thinnest readingtaken during the scan anddisplay the associated A-Scan.

Multiple Update Rates

Only the DMS 2 enablesthe user to set the defaultupdate rate.

> 4 Hz

> 8 Hz> 12 Hz

> 16 Hz

> 32 Hz (B-Scan & Min-Cap Modes)


29/34



DMS 2 Scans FASTER

32 Hz update rate in B-Scan and MIN-CAP modeallows users to scan faster.

Higher frequency update

rate = fast scanning withbetter coverage

Approx. Speed of 2

inches/second.

TopCOAT IS a Superior

Through CoatingMeasurement Technique


31/34



TopCOAT

Superior Thru-Coating Thickness Measurement

TC-560 4 Element Probe

No need to calibrate to coating thickness

Have Auto-Velocity Mode

Temperature Limit (130 F)

DMS 2 Coating Value Prominent


32/34



DMS 2 Coating Value - Prominent

With no data logger fileactive, the CoatingThickness value is largeand very easy to read

With data logger file active,small coating value is aboutthe same size as the 37DL+

text but easier to read


33/34



Auto-V Mode

No Material CalibrationNeeded

No Special CalibrationBlocks

Conclusion

DMS 2 is the gauge with thebest value vs. features

Works with a wider varietyof probes for solving

corrosion applicationsHas the best utility Softwareavailable
