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 pulloff tester (1) are refering to the models Z6(E) or Z16(E).

3.1.3 Units for the DYNA Z Instruments
The units bar, mbar/hPa, kPa, MPa, PSI mentioned in chapter 3.1.2 are those for the hydraulic pressure measured and normally displayed by the LEO 1 manometer and only for this.
For the use with the DYNA Z units this pressure display had to be converted for the required display (like the force in kN/lbf and to N/mm²/psi for the strength on a test disc of 50 mm diameter) by setting of conversion factors and units with letter sequences different from the ones for the hydraulic pressure display mentioned above. Up to 5 different conversion factors and units can be set and stored in the lines 1 to 5.
To display these units four letters and/or numbers had to be set. But only part of the letters were available.
For the force the units kN and lbf have been set:
• The letter sequence for the unit kN is Cnut (stored in line1)
• The letter sequence for the unit lbf is LbF0 (stored in line 2)
For the strength on a test disc of 50 mm diameter the units N/mm² and psi were added.
• The letter sequence for the unit N/mm² is nPnn (stored in line 3)
• The letter sequence for the unit psi is PSJ0 (stored in line 4)
You have been specially informed about additional and/ or other units set according to your requirements.

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).
Select the menu option "k-Factor".

The pull-off tester uses the k-Factor values of the factory calibration for operation (see chapter 4.2.5).
If you want to use the display unit with a different pulloff tester, select position m.
Set the k-Factor of the pull-off tester using the arrow keys .
Specifications for the kFactor can be found in the calibration certificate or on the type plate of the pulloff tester, depending on the model.
The measured values are calculated over the entire force area with the same k-Factor. This means that the displayed values deviate slightly more (approx.1.5%) from the actual value (due to the non-linearity of the sensor).
© 2006 Proceq SA
4.2.5 Calibration F10
The k-Factors determined during the factory setting are displayed for your information in the "Calibration F10" menu option (see Fig 4.6). Calibration is done in steps of 10% over the entire load area (10% - 100% of the nominal load).
Select the menu option "Calibration F10".
The following submenu appears in the display (11):

Warning!
The pulloff testers are available as a calibrat ed unit (pulloff 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.
4.2.6 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.

4.2.9 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).
Settings 19
This will not influence the speed of load appli cation and the duration of the measuring pro cedure, 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 seconds.
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).
Fig. 4.10 Flow Bar
Use the arrow keys
to set the display speed.
Example of possible settings:
- k-Factor: Position C (see chapter 4.2.4)
- Specified speed of load application: 0.1kN/sec
(see chapter 4.2.10)
- Test disc: Ø 50 mm (see chapter 4.2.3)
- Sample breaks at: 2N/mm 2 (= 3.9kN)

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/
(mm 2 x s).
For a medium speed of 0.050 N/(mm 2 xs) and a test disc with a diameter of Ø 50 mm, the speed is as follows in kN/s:
0.050 x 1963 x 0.001 ~ 0.10 kN/s

5 Measuring Process
5.1
Warning!
Before performing a measuring procedure, read through the relevant chapters for the required settings (see chapter 4). Incorrect settings will result in wrong measuring results!
Warning!
Observe the relevant standards and regula tions when performing preparatory work or settings for a measuring procedure (e.g., making cores).
Preparing the Measuring Procedure
Core
Fig. 5.1 Preparing the test surface
Test disc 6
Fig. 5.2 Test surface with
stuck on test disc
Cut into the test surface with a core drill (if necessary) so that the break can occur over the defined circular surface (see Fig. 5.1).
Attach the test disc (6) to the test surface using an adequate adhesive (see chapter 8, Appendix).
Wait until the required adhesive strength is reached.

Fig. 5.3 Preparing the pulloff tester
If the pulloff tester is to be stored for a longer period of time (23 months), move the piston (4) up and down 23 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).
© 2006 Proceq SA
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 avail able 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 pulloff tester. Premature repair or new calibration might become necessary!
After alignment, slightly release the draw spindle (14) with the wheel.
5.2 Measuring with the Digital Manometer
Fig. 5.4 Display of the digital manometer
Ensure that the pull-off tester (1) is prepared in accordance with chapter 5.1.
Ensure that the digital manometer (2) is switched off or switch it off.
Then press the "SELECT" key to switch on the digital manometer (2).
The pull-off tester is now ready for measuring. The current value is displayed.
For the normal case of peak value display switch to "PEAK on" as described in chapter 3.1.2 under
"Example: Setting of a new Zero Reference".
If the digital manometer is not under load and switched on in PEAK mode, the peak value may increase slowly to approx. 20 digits. This will not influence the measuring result.

Warning
Do not apply more force to the device than the permitted maximum nominal load as the seals of the pulloff tester might otherwise be dam aged. In certain cases, a force up to 10% greater than the permited maximum nominal load can be applied for a short period of time.
Warning
The device must never be exposed to perma nent load. Take the load off the pulloff tester after every measurement, as the seals of the pulloff tester might otherwise be damaged.
24 Measuring Process
Turn the crank (12) steadily clockwise until the specified test force is reached, or until the test surface breaks.
Always press the "ON" key after the measurement is complete to switch off the device or perform a new measuring procedure.
After each measurement, turn the crank (12) back counterclockwise until slight resistance is encountered.
Then turn the crank (12) maximum one turn in a clockwise direction.
The pull-off tester is now ready for a new measuring procedure.
5.3 Measuring with the DYNAMETER
5.3.1 Preparing the DYNAMETER
Check all settings in accordance with chapter 4.2.
After checking the settings and ensuring that the pulloff tester is not under load, press the "END" key to return to the measuring display.
Start the measuring procedure.
5.3.2 Carrying out the Measuring Procedure
Ensure that the pull-off tester (1) is prepared in accordance with chapter 5.1.
Press the "START/RESET" key.

Warning
Do not apply more force to the device than the permitted maximum nominal load as the seals of the pulloff tester might otherwise be dam aged. In certain cases, a force up to 10% greater than the permited maximum nominal load can be applied for a short period of time.
Warning
The device must never be exposed to perma nent load. Take the load off the pulloff tester after every measurement, as the seals of the pulloff tester might otherwise be damaged.
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.
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.
Two types of data storage are now possible depending on the option you have selected (see chapter 4.2.6):

The "PRINT/STORE" key can also be pressed several times during a measuring procedure (if sample changes, e.g. a fracture occurs). The values will then be stored in this order.
After every measurement, turn the crank (12) back counterclockwise until slight resistance is encountered.
Then turn the crank (12) one turn in a clockwise direction.
26 Measuring Process
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).
