3 Unpacking Of Equipment
Unscrew fixing steel sheet plates of upper side to wooden base of case and hold up upper side of wooden
case by means of carrying handles. Take out two M8 bolts fastening equipment to lower wooden case.
Locate equipment on a special table (see drawing of table enclosed) and fasten two M8 bolts by means of
eye bull putting on flat testing table.
Open left cover. Take out wooden safety parts. Take out also 3 off M6 bolts of top cover by means of 5 mm
special alyen key which is in accessory box with care. Take out plastic safety parts. Equipment is now ready
for testing.
4 Setting into Operation
Before starting to test, load application lever has to be in starting position. Locate part to be tested on testing
table, Insert Indentor to holder and choose load by means of load selector disc (according to testing method
in attached table).
5 Adjusting loading speed
Load application is adjusted by hydraulic system. Hydraulic oil is filled at our works and hydraulic
application speed is adjusted at our works. (But, working at extremely high temperatures or during
transportation due to wrong handling if oil is reduced you may add some oil again. To do this, open left
cover. There are two bolts on hydraulic piston Take out bolt on the left (A1). Add some oil (Tellus 37 or
similar) while adding oil, you can use load application lever forward and backward. This helps oil to settle
down easily. You can adjust hydraulic speed, by alyen bolt on the right (B1). If you turn this bolt lock wise
load application speed is decreased, if you turn anti clockwise it is increased.

6 Rockwell Hardness Testing (EN 6508-1, ASTM E18)
Rockwell Hardness testing method is evaluated from penetration depth of 120°diamond cone or ball
indenter with different dias (please refer to table enclosed).

For Rockwell tests, HRC, HRA, HRD tests Rockwell Diamond indenter to be chosen while 1/16” ball
indenter for HRB, HRF, HRG tests (see enclosed table) Using 1/8”, 1/4” ball indenters (optional) others
tests can be also achieved.
For Brinell tests, 2, 5 mm ball indenter to be used. Without using optical microscope, it is possible to see
Brinell values directly on screen (depth measurement) please see Operational Manual of DIGIROCK for test
menu enclosed. Materials to be tested by Brinell methods can easily be chosen in the menu shown below.
7 Brinell Hardness Testing (EN 6506-1, ASTM E10)
Brinell hardness testing method is made by different balls depending on material type, thickness and loads
applied. Diameters of ball indentations can be evaluated by optical system or portable microscopes.
You may also see Brinell values of Aluminyum, Copper, Brass (Bronze), Steel, Stainless Steel and Cast Iron
directly by DIGIROCK unit without using portable microscope. To do this, please refer to manual of
DIGIROCK for different materials. Insert 2, 5 mm indenter to holder. Apply position of load selector disc on
suitable load (62, 5 kgf or 187, 5 kgf) and do the same procedures as like Rockwell.

8 Prior to Test
Pay attention load application lever is in starting position .Using table, choose suitable indenter according to
test method to be applied. Locate indenter on holder carefully and gently tighten alyen screw using alyen
key.
9 Choosing the Test Load
Choose suitable Rockwell test load according to table 2 using load selector disc (In this position, load
application lever must be in starting position). Locate part to be tested on testing anvil.
