Page 3: Safety And Liability
1 Safety and liability These operating instructions contain important information about safe handling and maintenance of your new device. Before using the appliance for the first time, please read these operating instructions completely and carefully. Please keep the manual in a safe place for future reference. 1.1 Safety Instructions Your device is a high-precision instrument;... -
Page 4: Specification
considerable damage to the surface of the test specimen. The Vickers method uses an optical measurement, but a problem-free and correct measurement requires extensive expertise. Furthermore, there is no possibility to test a test piece of greater weight or solid parts for hardness. The ultrasonic hardness tester is based on the ultrasonic contact impedance method for performing comparable hardness tests on test specimens. -

Below is an image of the impression in prism form on the test piece, the size of the impression varying according to the material of the test piece. The shape of the impression is the same as the Vickers method and would require a strong microscope for observation.

Page 10: Safety Instructions For Handling
5 Safety instructions for handling 5.1 Preparation and control 5.1.1 Requirements concerning test pieces Minimum thickness The ultrasonic hardness tester uses a Vickers diamond indenter, so the Vickers hardness calculation formula is also used in the ultrasonic hardness tester. Thin layers or top coats of base material must have a minimum thickness (t). - Page 11 Material thickness of the test object, test load and hardness value （HV 0.2 up to HV 100） Important! According to the ultrasonic contact impedance method (UCI method), the sensor must come into contact with the test piece, then it starts to oscillate and the hardness value is determined.

Page 12: Measurement
Roughness of the test piece surface The applied test load (i.e. the selected UCI sensor) must be designed not only for the specific application, but also for surface quality and roughness of the fabric. For smooth and homogeneous surfaces a low test load can be applied, for surfaces of greater roughness and coarseness the highest possible test load should be applied. - Page 13 If this is the case, the user can perform the calibration himself. The HO device supports hand-held and motorized sensors, available in the SAUTER range. The sensor type must be set before measurement.
- Page 14 5.2.2 Measurement with a motorized sensor Select [Menu]-[Select probe]-[Motorized probe]- Select [Motorized probe]. After correct connection, place the sensor vertically on the test sample, then press the red button on the top of the sensor. An AUTO test is performed. After 2s, the main unit triggers an acoustic signal, which means that the test load has expired.
- Page 15 The result of the measurement is stored under [Memory settings]→ [Data overview], where all test results can be selected using the arrow keys [↑] and [↓]. Single test mode: After the acoustic signal, the display shows the message "Ready", which means that the first measurement has been completed. The test result is stored in [Memory Settings]→...
- Page 16 Group mode: After the acoustic signal, the display shows the message "Ready", which means that the 1st measurement has been completed. Then repeat the measurement 4 times. After the 5th measurement, two acoustic signals are triggered by the main unit and the display shows the message "Complete" in the upper left corner, which means that 5 measurements have been performed in this group.
