Page 4: Setting Test Parameters
The MET portable hardness testers are designed to measure hardness of metals and alloys in the most popular hardness scales, such as Rockwell C (HRC), Rockwell B (HRB), Brinell (HB), Vickers (HV), and Leeb (LD). Calibration on these scales are carried out directly by Phase II prior to shipment of each unit. The MET hardness testers offer additional “open”... - Page 5 Every level of the menu allows the selection of parameters or modes of operation. • The first level – ‘scale’ – allows to choose the current (operational) hardness scale from the following: HRC, HB, HV, HLD, H1, H2 or H3. •...
- Page 6 Procedure of Operation Preparation for Operation Visual Inspection Make visual inspection of the device, making sure that there is no mechanical damage to the electronic transducer, connective cable. Surface Preparation Prepare the area of the tested surface by removing moisture, lubricants, scale, oxidation, rust, etc. The roughness of the part to be tested and radius of curvature of the tested surface and also mass and size parameters of the article shall correspond to the parameters given in the hardness tester data sheet.

- Page 16 • Gently press straight down on the transducer body slightly until the diamond pyramid makes initial contact with the surface of your part. Using a little more force, increase the downward pressure . (The Blinking Transducer light will now immediately until the diamond pyramid is forced into the surface stay on constantly showing that you are making a good connection to the part) The effort should be made smoothly.

Page 17: Measuring Procedure
The First Measurement • Blinking of ‘transducer’ symbol on the display means that the hardness tester is ready to conduct measurements. Measuring Procedure Use the supplied Leeb test block to check your hardness tester prior to your own testing applications. Loading the impact device Press down the loading tube to lock the impact body. - Page 18 Start to Test Gently press the release button on top of the impact device while the work piece, the impact device and the impact body are all stable and the starting force coincides with the axis of the impact device ←...

Page 19: Maintenance And Repair
Battery Replacement: • Remove two rubber plugs on the back side Bottom half of the MET-U1A. Use the supplied hex wrench to loosen the two hex screws. Lift the metal battery cover off to expose the 4-AA batteries. It is recommended that you replace the batteries with a high quality NiMh set of rechargeable batteries. - Page 20 UCI- Ultrasonic Contact Impedance Method Terminology: Definitions: UCI Method UCI method Ultrasonic Contact Impedance, a hardness testing method developed by Dr. Claus Kleesattel in 1961 based on the measurement of the frequency shift of a resonating rod caused by the essentially elastic nature of a of the finite area of contact between the indenter and the test piece during the penetration.

Page 21: Leeb Hardness Test (Definition)
Leeb Measuring Method – (For MET-UD only) History The Leeb measuring method was first brought into measurement technology in 1978. It is defined as the quotient of an impact body’s rebound velocity over its impact velocity, multiplied by 1000. Harder materials produce a higher rebound velocity than softer materials. -
