2 Product Description

2.1

Field of Application

The DYNA pull-off tester is a mobile and versatile device with the following fields of application:

Measuring the adhesive strength of applied coatings:

This includes, for example, plastic coatings, concrete coats, mortars and plasters, bituminous coats as well as paint finishes and coatings of metals.

Determining the surface strength of concrete and other materials:

The surface strength is tested directly on the component.

Any measuring point can be used and there is no need to embed the sample in the concrete first.

The legs can be moved and/or extended on all models and the measuring procedure can be perfectly adapted to the test situation.

All measurements can be carried out using test discs with different diameters.

The standard diameter of a test disc is Ø 50 mm.

Test discs with other diameters can be ordered directly from PROCEQ or authorized agencies (see chapter 7.2,

Accessories).

All pictures of the pull-off tester (1) are refering to the model Z16(E).

4.2.4

k-Factor

The k-Factor serves for converting the electric signal emitted by the measuring cell (8, see Fig. 2.2) of the pull-off tester into the unit of the indicated measured value (force or tension).

To achieve maximum precision of the measured values, the pull-off tester with the DYNAMETER display unit is calibrated with ten load levels at our factory. These values are indicated in the menu option, "Calibration F10"

(see chapter 4.2.5, Fig. 4.6).

" Check to see if the serial number of the DYNAMETER matches the serial number of the pull-off tester (see chapter 3.2.2).

Warning!

The pull-off testers are available as a calibrated unit (pull-off tester - DYNAMETER display unit). The nominal tensile force in the display

(see Fig. 4.6) must be equivalent to the nomi-

nal value of the pull-off tester. The nominal

load and displayed k-Factor values of the

individual load levels must not be changed by the user. The values are only displayed for information purposes.

For new calibration procedures, PROCEQ offers separate calibration instructions to the testing authority.

Peak Value

With the menu option "Peak Value" you can set how values are to be displayed and stored.

" Select the menu option "Peak Value".

The following submenu appears in the display (11):

" Select the desired position using the arrow keys

DYNAMETER offers two basic possibilities for the dis-

play and storage of values:

If you select "Memory on", the DYNAMETER automatically stores the peak value after the force has significantly decreased by approx. 1% of the nominal value during a measuring procedure (if the sample breaks or in the case of manual relief).

If you select "Memory off", you can perform measuring procedures with loads up to the specified test force. In this case the data of the current measurement must be stored manually.

To document that the test force has been reached proceed as follows:

" When the specified test force has been reached press the "PRINT/STORE" key on the keyboard to store the current value.

Flow Bar

The flow bar indicates the tendency of the load increase or decrease which is influenced with the crank of the pull-off tester.

With the menu option "Flow Bar" you can control the

display speed of the bar movement. This setting also influences the display speed of the bar movement of the load pacer (see chapter 4.2.10).

© 2002 PROCEQ SA

This will not influence the speed of load application and the duration of the measuring procedure, which is determined by means of the load pacer (see chapter 4.2.10).

" Select the menu option "Flow Bar".

The following submenu appears in the display (11):

With these values set, the measuring procedure takes approx. 40 s.

" Select approx. 2/3 of the maximum speed for the flow bar.

If this speed is set, the flow bar and the load pacer bar move across the measuring display once from left to right.

During longer measuring procedures, the flow bar and the load pacer bar might move across the measuring display from left to right several times.

This avoids the display speed being too low.

You can change the display speed according to your requirements. The display speed is also influenced inversely proportional to the specified speed of load application (see chapter 4.2.10).

4.2.10 Load Pacer

With the menu option "Load Pacer" you can specify the speed of load application prescribed by the relevant standards.

While the measuring procedure is performed, the bar movement of the load pacer determines the flow bar´s speed of movement (see chapter 4.2.9).

The unit for the preselection must always be "kN / s" even if another unit had been selected for the display.

" Select the menu option "Load Pacer".

The following submenu appears in the display (11):

Conversion example:

The speed of the load increase (in accordance with EN

1015-12, chapter 8) is between 0.003 and 0.100 N/

Preparing the pull-off tester

If the pull-off tester is to be stored for a longer period of time (2-3 months), move the piston (4) up and down 2-3 times by turning the crank (12) of the hydraulic pump (3) in a clockwise and counterclockwise direction. This reduces friction losses caused by the piston seals.

Warning!

Avoid hasty, jerky movements, particularly when the piston is in its initial and end

position, because otherwise the piston might jam (see also chapter 6.2.1, page 24).

Measuring Process 19

" Turn the crank (12) back to its initial position in a counterclockwise direction until slight resistance is encountered (see Fig. 5.3).

" Then turn the crank (12) once in a clockwise direction

(to relieve the hydraulic system).

This ensures that the full piston stroke is available during the measuring procedure.

" Connect the coupling (15) of the draw spindle (14) to the draw bolt of the test disc (6).

" Turn the wheel (13) clockwise until slight resistance is encountered.

" Position the pull-off tester in such a way (1) that the tensile force is applied perpendicular to the test surface:

To achieve this, adjust the legs (16) of the pull-off tester (1) until no "pulling at a slant" can occur.

"Pulling at a slant" during measuring will falsify the measuring result and cause increased wear of the pull-off tester. Premature repair or new calibration might become necessary!

" After alignment, slightly release the draw spindle (14) with the wheel.

Measuring procedure

" Turn the crank (12) steadily clockwise to increase the force on the test surface.

The movement of the crank directly influences the speed of the flow bar in the measuring display (see chapter 4.2.9).

" Turn the crank (12) just enough for the flow bar to follow the speed of the load pacer flow bar.

22

Depending on the display speed (see chapter

4.2.9) and the value of the specified test force, it might be necessary to move the flow bar 2 or 3 times from left to right before the specified peak value is reached or the sample breaks.

Measuring Process

Two types of data storage are now possible depending on the option you have selected (see chapter 4.2.6):

Measuring with the

"Memory on" setting

After the force of the pulloff tester has dropped by approx. 1% of the nominal load, "Peak" flashes in the measuring display and the peak value is displayed and stored.

The DYNAMETER stores the data of

- Peak value

- Sample no.

- Test surface (if preselected, see chapter 4.2.3).

Measuring with the

"Memory off" setting

" When the specified value has been reached press the "PRINT/

STORE" key:

The DYNAMETER stores the data of

- Current value

- Sample no.

- Test surface (if preselected, see chapter 4.2.3).

The "PRINT/STORE" key can also be pressed several times during a measuring procedure (if sample changes, e.g. a fracture, occur). The values will then be stored in this order.

" After every measurement, turn the crank (12) back counterclockwise until slight resistance is encountered.

© 2002 PROCEQ SA

" Then turn the crank (12) one turn in a clockwise direction.

If you want to carry out a new measuring procedure:

" Prepare the pull-off tester (1) according to the instructions (see chapter 5.1).

" Check all settings (see chapter 4.2).

" Press the "START/RESET" key.

The peak value in the measuring display is deleted and the sample number is increased by 1.

The pull-off tester (1) is now ready for a new measuring procedure.

5.3.3

Display of the Measured Values

After every measuring procedure the stored values can be displayed directly on the DYNAMETER (9):

" Select the menu option "Data Output" in the main menu (see chapter 4.2.1).

" Select "Display Data" in the submenu.

" Select the desired sample number using the arrow keys #$ .

5.3.4

Storage Capacity of the DYNAMETER

The memory capacity is 1000 groups. When the memory is full, no further values will be accepted.

For this reason it is important that you transmit the data to a printer or PC in time (see chapter 4.2.1).

Afterwards you can delete the memory (see chapter

4.2.1).

6 Maintenance, Storage and Care

6.1

Cleaning After Each Use

Warning!

Never immerse the DYNAMETER and pull-off tester in water or wash it under a running tap!

Use neither abrasives nor solvents for cleaning!

6.1.1

Pull-Off Tester

" Clean the pull-off tester with a clean, dry cloth.

" If necessary, clean the gaps with a pneumatic pump

(no compressed air!).

" Clean the digital manometer or DYNAMETER with a clean, dry cloth after use.

" Clean dirty input sockets and connectors of the DYNA-

METER with a clean, dry brush.

6.2

Performance Check Before Each Use

6.2.1

Pull-Off Tester

" Ensure that the pull-off tester is complete.

" Ensure that the coupling (15, see Fig. 5.3) is screwed in correctly.

" Fix the legs (16) in their basic position.

" Check to see if there are traces of oil on the pull-off tester.

Warning!

Oil is an indication of leaking seals. Check the oil level immediately!

" Turn the crank (12) back counterclockwise until slight resistance is encountered (initial position).

" Measure the distance H

A

(see Fig. 6.1) between the highest point of the device plate (5) and the outer top edge of the piston (4) in this position.

" Now turn the crank (12) clockwise until slight resistance is encountered (end position).

" Measure the distance H

E tion.

(see Fig. 6.1) in this posi-

The difference of level ∆H (H

E

- H

A

) between the initial and end position should be 3 - 4 mm.

" Turn the crank (12) back counterclockwise until it reaches its initial position.

" Then turn the crank (12) one turn in a clockwise direction.

Warning!

If the difference of level is too small, the oil volume will not be sufficient. Immediately send the device to an authorized service center.

" Check the cables for damage.

" Check the battery capacity (see chapter 3.2.2).

If a battery life of 4 to 6 hours is indicated on the DYNAMETER when it is started up, you should take a new set of batteries to the measuring site.

6.3 Storage

" Store the DYNAMETER and pull-off tester in the original case in a clean, dust-free room.

" If the device is not used for a long period of time, remove the batteries from the DYNAMETER or digital manometer.

6.4

Maintenance

6.4.1

Pull-Off Tester and Display Units

We recommend performing a general check and new calibration of the pull-off tester and DYNAMETER every

two years.

Warning!

Any warranty or liability claims will expire if maintenance work is carried out improperly.

For this reason, always send the pull-off tester and its components to a service center authorized by PROCEQ.
