Precautions during installation

1) Ensure to check power supply in the installation place! - This product is designed for AC 220V, 1 A, 1ph, 50~60Hz. - If power voltage is wrong, over current may cause a damage of the machine. - If you have different power voltage, please contact us.

2) Check for power earthing status. - Earthing work can prevent electrical shock.

3) Check input power cable - If it is possible, use exclusive power cable for the machine. - If the thickness of power cable in the input part does not match the capacity, it can cause a fire owing to over load.

4) Install the machine on a flat place. - This product is precise machine. - Never install the product on a slope or uneven place.


- Please maintain level.

Power and earthing work

1) Power work - AC 220V, 1 A, 1ph, 50~60H

2) Earthing work [Caution] - This product is designed for single phase 3 wire system based on standard of electric equipment. Be sure to connect the power cable to the plug with earthing. - If there is no earthing, it can damage electric and electronic parts owing to thunderbolt, etc. - In addition, it may cause electric shock.

OutlineBrinell hardness tester presses an indenter of steel ball onto test sample with regular test load,and divide the load applied to a test sample by mark area (diameter) to get hardness value. The values are divided into HB, HBS, HBW according to the types of the steel ball. Usually, Brinell hardness tester is used to test hardness of casting, cast steel, and metallic material.

① Select test load (500 ~ 3000) kgf, and put weight hanger and test load weight on the machine. ② Select a indenter(5mm or 10mm) and mount it on indenter holder.

③ Select Anvil (flat Anvil or VAnvil) and connect it to the upper part of the screw.

④ Place a test sample on Anvil, turn the screw handle clockwise to rise the screw to softly contact indenter and the test sample.

⑤ Turn valve clockwise to close it and pump operate operating lever up and down. At this point, check the pressure gauge. When load rises up to the selected load, operate the pump slowly and stops operating the pump when test load weight rises about 40㎜.

How to test (DTB‐500)


⑥ After load maintain time, open the valve by turning counterclockwise to remove the load. At this point, if you open the valve suddenly, test load will be reduced rapidly giving impact to the machine. Therefore, conduct all operations slowly.

⑦ Turn the screw handle counterclockwise to take the test sample out, and measure the diameter using measuring microscope and then read hardness value referring to attached Conversion Table

⑥ When the steel ball contact closely with a test sample, press START button.

⑦ To rapidly stop a test, press Emergency Stop button. At this point, the applied pressure will be back to initial status.

⑧ Turn the screw handle counterclockwise to take the test sample out, and measure the diameter using measuring microscope and then read hardness value referring to Conversion Table on the side of the machine or Reference Table in the manual.

Precautions during test

- Roughly process contacting surface of test sample and Anvil to make them flat for a test. - Make test sample and indenter axis to be vertical and mark surface should not to be too coarse. - Generally, steel ball indenter with 5, 10㎜ diameter are usually used for Brinell hardness tester, and load of 3000, 1500, 1000, 750, 500㎏f are usually used.

- Selection of D (diameter of indenter) and P (test load) is important and the following conditions must be met. - If D/d is smaller than 0.25, the mark is too small to measure it and error of measurement is getting bigger. If D/d is bigger than 0.6, diameter of pressure mark does not change much according to the variation of hardness. Therefore, we can see variation of hardness clearly.

- Combination of test load and indenter diameter P: test load (kgf) D: indenter diameter(㎜)

0.25 < d/D < 0.60 ( KS B0805 )


- Test load kgf

- If you use a steel ball indenter to test strong light alloy, permanent deformation will occur to the indenter. Therefore, we use a steel ball indenter for test sample below HB 450 and we use a cemented carbide ball indenter for HB 600~650.

- Marking hardness valve: mark the type and size of diameter load of the used indenter.

- Also mark the standard and load of the steel ball (Ø) along with hardness value.* ex) If you get value of 321 by applying load of 3,000kgf with steel ball of 10mm, ☞ put down HBW (10/3000) 321.

- In case of the long time use of the machine, hydraulic fluid (#68) of oil tank (cylinder) will slowly flow into the auxiliary tank in the control box. However, there is auto function to supplement the hydraulic fluid in the auxiliary tank to the main cylinder. Accordingly, you do not have to replace the fluid frequently.
