Quick Start

The PosiTector 200 powers-up when the center navigation button is pressed. To preserve battery life, the instrument powers n after approximately 5 minutes of no activity. All settings are

retained.

1. Remove the protective rubber cap from the probe.

2.	Power-up Gage by pressing the center navigation	button.
3.	Zero the probe. (see pg. 5)
4.	Adjust to a known thickness, if necessary. (see pg. 6)
5.	Measure the part. (see pg. 3)

Menu Operation

Gage functions are menu controlled. To access the Menu, powerup the gage, then press the center navigation button.

	Navigation Button
	Up		To navigate, use the Up and Down buttons to
	Center		scroll and	to SELECT.
			Select Exit to exit from any menu.
	Down
		The center	button is purposely recessed to help
		eliminate un	ntional powering-up of the gage.

Probes

To disconnect a probe from a body, power-down the instrument and slide the plastic probe connector horizontally (in the direction of the arrow) away from the body. Reverse these steps to attach a new probe.

When powered-up, the PosiTector automatically determines which probe is attached and does a self-check.

PosiTector 200 probes are available for measuring a wide variety of coating thickness applications.

B probe - 13 to 1000 microns (0.5 to 40 mils)

Ideal for polymer coatings on wood, plastic, composites, etc. C probe - 50 to 3800 microns (2 to 150 mils)

Ideal for thicker coatings on concrete, fiberglass, etc.

D probe - 50 to 7600 microns (2 to 300 mils)

Ideal for thick, soft (attenuative) coatings such as polyurea

Range limits apply to polymer coatings only.

Additionally, the PosiTector accepts a number of probe types including magnetic and eddy current coating thickness, surface profile, environmental and ultrasonic wall thickness probes.

For the latest information on probe interchangeability, see www.defelsko.com/probes

Couplant

Couplant is required to propagate ultrasound into the coating. Water is a good couplant for smooth coatings. Use the supplied glycol gel for rougher coatings. While it is unlikely that the couplant will damage the finish or leave a stain on the surface, we suggest testing the surface by using the couplant on a sample. If testing indicates that staining has occurred, a small amount of water can be used instead of couplant. Consult the Material Safety Data Sheet available on our website and your coating supplier if you suspect the couplant may damage the coating. Other liquids such as liquid soap may also be used.

PosiTector 200 - Theory of Operation

PosiTector 200 probes emit a high frequency sound pulse that
travels into the coating via a coupling gel and reflects from ANY
surface that is different in density. Coating thickness readings are
obtained by measuring the time taken for the ultrasonic signal to
propagate from the probe to the coating/substrate interface and
back. The travel time is divided by two and multiplied by the
velocity of sound for the coating to obtain the thickness of the
coating.

How to Measure

1. Remove the protective rubber cap from probe.

2. Power-up Gage by pressing the center navigation button.

3.Apply couplant (see pg. 2) to the surface of the part.

4.Place the probe FLAT on the surface and press down.

5.Lift the probe when you hear a double BEEP,

- OR - leave probe on the surface in the same location for continuous measurements.

6.When completely finished, wipe the probe clean of couplant then return the Gage to the protective pouch. There is no need to disconnect the probe from the PosiTector during storage.

Calibration, Verification and Adjustment

Three steps ensure best accuracy…

1.Calibration - typically done by the manufacturer or a qualified lab. All probes include a Certificate of Calibration.

2.Verification of Accuracy - as done by the user on known reference standards such as the included plastic shims or optional coating thickness standards.

3.Adjustment - to a known thickness.

Calibration

Calibration is the controlled and documented process of measuring traceable calibration standards and verifying that the results are within the stated accuracy of the Gage. Calibrations are typically performed by the Gage manufacturer or by a certified calibration laboratory in a controlled environment using a documented process.

Verification

Verification is an accuracy check performed by the user using known reference standards. A successful verification requires the Gage to read within the combined accuracy of the Gage and the reference standards.

Adjustment

Adjustment, or Calibration Adjustment is the act of aligning the

Gage's thickness readings to match that of a known reference sample in order to improve accuracy of a gage on a specific coating. See Thickness pg. 6

Cal Settings Menu

Zero

The probe must be periodically zeroed using the Zero menu option to compensate for both extreme temperature and probe wear effects. Before using, allow the probe to reach ambient temperature. Wipe the probe clean of couplant. The icon appears after probe is zeroed.

If measurements will be made in extreme hot or cold temperatures, it is recommended to Zero the probe in the working environment. If measurements will be made on rough substrates, it is recommended to periodically Zero the probe to compensate for wear.

Set Range

The measuring range of each probe can be changed depending on the specific application or the expected thickness range of the coating system.

For most applications, the default range values do not have to be adjusted. But some conditions, like surface roughness, may cause the Gage to display very low or non-repeatable readings. In this case, the low range may be increased to cause the Gage to only display readings above the Lo value set by the user.

To adjust Set Range values...

1. Select or .

2. Use the (-)(+) buttons to decrease/increase the displayed value.

IMPORTANT:

The PosiTector 200 interprets the largest “echo” or “echoes” within the selected range as the coating/coating or coating/substrate echo. If the coating thickness is outside this range, incorrect or dashed readings may occur.

5

Here are some typical Range settings...

Expected paint thickness		Lo	Hi
500µm (20 mils) on concrete		130µm (5 mils)	1000µm (40 mils)
50µm (2 mils) on wood		25µm (1 mil)	250µm (10 mils)
Thickness
The PosiTector 200 measures most polymer coatings accurately
out-of-box with no adjustment required.

To determine if an adjustment is necessary, select a coating sample of known thickness as close as possible in composition to the intended application. For best results, the thickness of the sample should be equal to or slightly greater than the maximum expected thickness of the coating to be measured.

Measure the coated sample. If the average of a series of
measurements on the sample is not close to the known
thickness...
1. Select the Thickness menu option.
2. Use	(-) or (+) to decrease/increase the displayed measurement
thickness value to match the known thickness of the sample.
3. For	Advanced models with multiple layers selected, use the
Down	navigation button to select the next layer and adjust as
necessary.
4. To save adjustments, use Down navigation button to highlight
OK and press the center navigation				button.
Polyurea			(PosiTector 200 D probes only)
When checked, the Gage loads a pre-programmed calibration
adjustment optimized for measurement of polyurea coatings.
Cal Lock
When checked, the			icon appears and the current calibration
adjustment is “locke			to prevent further user adjustments.
Cal Reset
Restores the gage back to factory calibration and range settings.
The	icon will appear on the display.

Setup Menu

	Reset
Reset (soft reset) restores factory settings and returns the Gage to
a known condition. The following occurs:
-	All batches, stored measurements, images, batch names and
	screen captures are erased.
-	All calibration and range adjustments are cleared and returned
	to the Gage’s factory settings.
-	Menu settings are returned to the following:
	Memory = OFF				Bluetooth = OFF		Layers = 1
	Graphics		= ON		Display = None		Layer Name = Layer 1
	Cal Lock		= OFF				Layer Color = blue
Perform a more thorough Hard Reset							by powering down the
Gage, waiting several seconds, then simultaneously holding both
the center					and (+)	buttons until the Reset symbol
appears. This			urns the instrument to a known, “out-of-the-box”
condition. It performs the same function as a menu Reset with the
addition of:
-	Bluetooth Pairing info is cleared.
-	Menu settings are returned to the following:
	Units = microns					Battery Type = Alkaline
	Flip Display = Normal					Backlight = Normal
	White on Black = OFF					USB Drive= ON
	Language = English					Auto Sync = OFF
		Date, Time and WiFi are not affected by either Reset.

Battery Type

Selects the type of batteries used in the Gage from a choice of

“Alkaline”, “Lithium” or “NiMH” (Nickel-metal hydride rechargeable). If NiMH is selected, the Gage will trickle charge the batteries while connected via USB to a PC or optional AC charger. The battery state indicator icon is calibrated for the selected battery type. No damage will occur if the wrong battery type is selected.

DeFelsko recommends the use of eneloop (NiMH) rechargeable batteries.

Graphics	(Advanced models only)
When selected, the Gage displays a
graphical representation of the ultrason-
ic pulse as it travels through the coating
system.
As the probe is depressed and the
ultrasonic pulse travels through the
coating system, the pulse encounters
changes in density at the interfaces
between coating layers and between the
coating and the substrate.
These interfaces are depicted by a "peak". The greater the change
in density, the higher the peak. The more gradual the change in
density, the greater the width of the peak. For example, two coating
layers made of essentially the same material and "blended" would
result in a low, wide peak. Two materials of very different density
and a well-defined interface would result in a high, narrow peak.

The PosiTector 200 chooses the highest peak (single layer) or peaks (multi-layer) within the Set Range. For example, if the number of layers is set to 3, the three highest peaks would be identified with small red triangles. The peak values are also displayed numerically as thickness measurements.

The Graphics display can also be accessed using the Set Range menu option.

Use the navigation Up (move left) and Down (move right) buttons to highlight icons on the graphic display.

Zoom - Visually magnifies the waveform of the displayed peaks for more visibility. Pressing the (+) or (-) button repeatedly will increase/decrease the zoom.

Set Range - Press the (-) or (+) buttons to adjust the ge Lo or Hi measuring range. (see pg. 5)

8

Cursor - The Cursor allows for further analysis of displayed
veform. Use the			(-)(+) buttons to move the green cursor line left
or right over the waveform. The thickness value is displayed at the
top right	of the		cursor line. This feature is particularly
useful in	multi-layer applications			where there are more than
3 distinct layers.
Screen Capture - Press				to capture and save an image
y of the current display. The last 10 screen captures are stored
in memory and can be accessed when connected to a computer.
(see PosiSoft USB Drive pg. 10)
	Press and hold the (-)(+) buttons simultaneously to
capture any screen.
Menu - Press			to access the Gage’s main menu.
Exit - Press			to close the Graphics display. Press the Up
on to return to			Graphics display.
Layers			(Advanced models only)
Advanced models of the PosiTector 200 are capable of
numerically displaying up to 3 individual layer thicknesses in a
multi-layer system.

Select the Layers menu option to:

- Choose up to 3 individual layer thickness values.

- Edit layer names and Batch Chart colors.

• Before setting up the Gage for multi-layer measurement, it is recommended that you first take measurements in single layer mode and interpret the results using the Graphics option. (see pg. 8)

• When a batch is Open, press the Up button to view the

Batch Chart.

El PosiTector 200 interpreta el "eco" mayor dentro del rango seleccionado como econ del recubrimiento/recubri miento

o eco de recubrimiento/ sustrato.

Acoplante

El acoplante es necesario para propagar el ultrasonido en el recubrimiento. El agua es un buen acoplante para revestimientos lisos. Utilice el gel de glicol suministrado para revestimientos más ásperos. Si bien es improbable que el acoplador dañe el acabado o deje mancha en la superficie, le sugerimos que realice una prueba sobre una muestra. Si la prueba indica daño en la superficie, puede utilizar una pequeña cantidad de agua en lugar del acoplante. Consulte la hoja de datos de seguridad del material disponible en nuestro sitio Web. Contacte a su proveedor de recubrimiento si sospecha que el acoplante puede dañar el revestimiento. También pueden utilizarse otros líquidos como el jabón líquido.

PosiTector 200 - Fundamento de Operación

Las sondas PosiTector 200 emiten un pulso de sonido de alta frecuencia que viaja por el revestimiento a través de un gel acoplante y se refleja en CUALQUIER superficie que tenga densidad diferente. Las lecturas de espesor de recubrimiento se obtienen midiendo el tiempo que necesita la señal ultrasónica para propagarse desde la sonda a la superficie de recubrimiento o sustrato y regresar. El tiempo de transmisión se divide en dos y se multiplica por la velocidad del sonido en el recubrimiento y así obtener el espesor del recubrimiento.
