4.3 Control elements

The control elements area contains all elements you need for positioning in the
Workflow. You can swivel in lenses and indenters and move the test unit in the X-Y-Z-
axes.

1 Positioning in the Z-axis

2 Positioning in the X-Y-axis Test anvil or specimen holder
3 Positioning in the X-Y-axis Joystick
4 Positioning lenses and indenters
5 Setting the zoom level

Several options are available for positioning in the Z-axis:

▪ The slider
can be used to move the lens to the specimen or the surface.
▪ Use the AF Camera function
to optimize the image when the lens is already located in the area of specimen or
surface.
▪ The AF Indentation function
can be used to automatically locate and identify the specimen. However, this
function leaves a little indentation.

Several options are available for positioning in the X-Y-axis:

▪ On the test anvil or specimen holder
▪ With the joystick
▪ Moving in the live image
The control element Turret can be used to position lenses and indenters.

Whenever making positioning movements, always check that the test unit is positioned
high enough above the specimen holder to prevent a collision between lenses/indenter
and specimen holder.
Should a lens interfere with the specimen holder, you may have to recalibrate the lens.
See Chapter "Adjusting lenses (Assistant - Objective Lenses)", page 8-17.

4-4
 Hardness Tester Basic operation
DuraScan 50 G5 / 70 G5 / 80 G5

4.3.1 Positioning in the Z-axis

4.3.1.1 Slider
The slider can be used to move the test unit up and down. This allows you to:
▪ focus the image.
▪ raise or lower the indenter.
With the bar in the middle, the test unit is moved continuously up or down.
The two arrows at the top and bottom end of the slider move the test unit up or down in
steps.
When rapid traverse (rabbit icon) is active, the test unit moves at a 10 times higher
speed. Manual focussing is not possible when rapid traverse is active. Rapid traverse
can only be activated when the indenter is swivelled in. It is deactivated automatically
when the turret position is changed.
Use the slider to move the optical system to the specimen or surface area. Next, use the
AF Camera function to optimize the image.

4.3.1.2 AF Camera
The AF Camera function is used when the lens is already in the specimen or surface
area.
In other words, use the slider to move the lens to the specimen or the surface before
you select the AF Camera function.
The AF Camera function automatically creates an optimum image without any further
user activities:
▪ The image is focused.
▪ Brightness is optimized.
Wherever possible, select the AF Camera function to ensure measured values that are
objectively comparable.
The perception of the focus by the human eye varies widely, which can result in user-
related differences in the test evaluation.

4.3.1.3 AF Indentation
The AF Indentation function is used for automatically locating and identifying the
surface of a specimen.
The indenter is automatically moved to the workpiece, where it leaves a little indentation
with a test load of approx. 10 g and a diagonal of 10 - 15 µ. Next, the indenter is raised
slightly.
The lens with the lowest magnification is swivelled in and automatically adjusted for an
optimum image.
The optimum working height is then approximately 0.3 mm above tje workpiece.

 Hardness Tester Basic operation
DuraScan 50 G5 / 70 G5 / 80 G5

4.10 Ring light

The ring light option with dark field illumination is mainly used for Brinell measurements
in cases where the surface integrity of the test material is poor. It is most suitable for use
with materials such as non-ferrous metals and, in general, materials of a Brinell
hardness below 250 Brinell. The ring light improves contrast, in particular for Brinell
indentations on relatively uneven surfaces.
Ring light and adapter are available as accessories for all DuraScan G5 units.
The aluminium ring light attachment is slipped on and fasten with a stud screw. Two
adapter rings are included in the ring light delivery that permit the different diameters of
the objective lenses to be compensated for. The ring light can only be used with
2.5x/4x/10x lenses.

Installing the ring light To install the ring light, first remove the lens ring and replace it with the ring light
adapter.
 Remove the lens (if installed).

 Attach the ring light lens adapter (1) and tighten it with the screws.
 Install the required lens. See "Installing the lens".
 If necessary: Use an adapter ring.
 Slip the aluminium slide-on attachment (ring light) (2) on the lens such that the long
side face of the slide-on attachment is parallel to the engraved number on the turret.
 Tighten the stud screw.

4-15
 Hardness Tester Basic operation
DuraScan 50 G5 / 70 G5 / 80 G5

Measuring with the ring To take a measurement with the ring light, you must additionally activate the ring light
light via an optional button on the Method screen in the software. Dark field illumination is
activated automatically. The evaluation algorithm is inverted and the image evaluation
program searches for a bright test indentation on a dark background. To return to using
the standard evaluation algorithm, simply use the same button to deactivate the ring
light. The ring light can remain attached to the lens in this case.

Adjusting the ring light If a test indentation does not have optimum illumination, the distance between the ring
light and the test indentation must be adjusted. To do this, slide the aluminium slide-on
attachment onto the lens in the correct position, and fasten it with the stud screw.

Example of a test indentation with sub-optimum illumination

4-16
 Hardness Tester Basic operation

6.1 Specimen screen

The Specimen screen opens automatically after login.

The Specimen area can be used to create the specimens to be measured and select the
test type.
You have the following options for creating specimens:
▪ You can create new specimens.
▪ You can load specimens that have already been measured and saved, and use
them as templates.

6.1.1 Creating new specimens

 In the Specimen area, select Add Specimen > New Specimen.

A specimen is created. ecos Workflow automatically assigns a free number to the new
specimen.
Alternatively, you may select a different name:
 Enter the required name in the Specimen Name box.

A duplicate name is recognized by the system and rejected.

6-1
 Hardness Tester Enhanced settings and
functions
DuraScan 50 G5 / 70 G5 / 80 G5

At Directory, you can see the default directory that is used to store the specimen data.
How to change the default directory is described in chapter "File Locations tab", page 8-
8.
At Test Type, you can select the type of measurement you wish to perform: Single
measurement, series measurement, CHD, Nht, Rht.

A basic distinction is made between measuring an individual test point and measuring a
series.

Single measurement Single measurement is carried out to measure an individual test point.

Series measurement In series measurement you measure predefined series.

Series measurement uses the following test types:
▪ Series measurement
▪ CHD
▪ Nht
▪ Rht

CHD CHD or case hardness depth is defined by determining the effective

depth of the carburized and case-hardened layer. With the HV1 test
method, the typical CHD limit is 550 HV.
Nht The Nht nitride hardening depth is defined by determining the
effective hardness depth after nitriding. The typical Nht limit
corresponds to the current core hardness of +50 HV with test method
HV0.5.
Rht The Rht surface hardness depth is defined by determining the
effective hardness depth after flame or induction hardening. The
typical Rht limit is 80% of the surface hardness of the HV1 test
method.
At the bottom of the screen, you can find the User boxes (see "User boxes tab", page
8-6) that you can fill out for subsequent reporting (see "Generating a test report", page
7-5), as well as a comments box in which you can enter free text.
