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. Hold top cover up with care. Pay attention
not to touch Rockwell Dial gauge. Take out plastic safety parts. Equipment is now ready for
testing.
4 Setting into Operation for Rockwell Hardness Testing
Before starting to test load application lever (KL2) (8) has to be in starting position (see drawing
and picture). Locate part to be tested on testing table, Insert indenter to holder (ML3) (5) and
choose load by means of load selector disc (VL1) (14) (according to testing method in attached
table)
5 Testing
As soon as indenter touches on part, actuating main spindle (ML1)) (12) by means of arms (SM1)
(13) Rockwell dial gauge pointers start movement. Keep going until big pointers at “0” and small
pointer at 3 in red dot. Now Pre –load is applied. (If big pointer is exceeded by ±3 points start to
test again) Then apply total load application lever
(KL2) (8) to forward (see drawing) and follow movement of big pointer until it stops. Wait 3-5 sec.
more. Then take back lever (KL2) (8) to starting position. And read value on display. Black
numbers on dial gauge for HRA, HRC and HRD with diamond indenter. Red values for HRB, HRE,
HRF etc. with ball indenters.
6 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 (PS1) Take out bolt on the left (A1). Add
some oil (Tellus 37 or similar) While adding oil, you can use load application lever (KL2) (8)
forward and backward. This helps oil to settle down easily. You can adjust hydraulic speed, by
allen bolt on the right (B1). If you turn this bolt clockwise load application speed is decreased, if
you turn anti clockwise it is increased.
7 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).

8 Brinell Hardness Testing (EN 6506-1, ASTM E10)
Brinell hardness testing method is made by different balls depending (for BMS 200-RBOV only 2,
5 mm ball) on material type, thickness and loads applied. Diameters of ball indentations can be
evaluated by optical system built-in hardness tester.

9 Setting into Operation for Brinell Hardness Testing
Locate 5X objective (16) on optical system
Before starting to test, load application lever (KL2) (8) has to be in starting position (see drawing
and picture) Locate part to be tested on testing table (10), Moving lever of sliding table (11) to
the left , assure testing table (10) to touch stopping bolt.
Insert 2, 5 mm ball indenter to holder (ML3) (5) and choose load by means of load selector disc
(VL1) (14) (according to table shown above)
IMPORTANT: For Brinell and Vickers tests quick lift lever (7) always must be in forward
position touching the stop pin.
Apply pre-load and total load as described in Rockwell testing.
Follow movement of big pointer until it stops. Wait 3-5 sec.more.Then take back lever (KL2) (8) to
starting position. Move quick lift lever (7) from right to left until it touches stop pin.
Move quick lift lever (7) from right to left until it touches stopping pin.(in this case indenter to be
separated from the surface of the part to be tested)
In this case, move the lever of sliding table to the right carefully (11) until testing table touches
micrometer.
Observe, ball indentation as per shown in eyepiece of microscope (OP-1)
9.1 Sample of reading indentation
Drawing: OP-2
Adjust, measuring moving line by means of micrometer of eyepiece (2) until it touches leftist side
of indentation. Then move, measuring line from left to right until it touches rightest side of
indentation. Than calculate value.
For example, value shown in OP-2 can be calculated as follows.
Every single line is 100 unit. (In Brinell testing total magnification is 75X when 5X objective is
used) One line of eyepiece micrometer is 0,002 mm.
100X6 = 600, Plus 24 unit shown on micrometer.
Total = 600 + 24 = 624 .Total value = 624 X 0,002 = 1.248
From the related table 145 HB 2, 5 / 187, 5 obtained.
10 Vickers Hardness Testing (EN-6507-1, ASTM E-92)
Vickers Hardness testing method is made by 136° Vickers pyramid indenter. Vickers indentation
can be evaluated by optical system built-in hardness tester.
(For this method, only 30kgf available with BMS 200-RBOV)

11 Setting into Operation for Vickers Hardness Testing
Locate 10X objective (16) on optical system
Assure all points same as Brinell test before start to operation.
Insert Vickers diamond indenter to holder (ML3) (5) and choose 30 kgf load by means of load
selector disc (VL1) (14)
Actuate Vickers test using same steps as per mentioned for Brinell test.
Observe, pyramid indentation as per shown in eyepiece of microscope (OP-1)
Sample of reading indentation
Drawing: OP-3
Adjust, measuring moving line by means of micrometer of eyepiece (2) until it touches leftist side
of indentation. Then, move, measuring line from left to right until it touches rightest side of
indentation. Than calculate value.
For example, value shown in OP-3 can be calculated as follows.
Every single line is 100 unit. (In Vickers testing total magnification is 150X when 10 X objective is
used) One line of eyepiece micrometer is 0,001 mm.
100X3 = 300, Plus 45 unit shown on micrometer.
Total = 300 + 45 =345.Total value = 345 X 0,001 = 0,345
From the related table 467 HV30 obtained.
