2.4. Selecting the right Equotip impact device type
For optimized testing of diverse metallic materials and sample geometries, a range of impact
device types is available as follows:
Type Application
Impact Energy
D
Universal unit.
For the majority of your hardness testing requirements.
11 Nmm
G
Increased impact energy.
For solid components, e.g. heavy castings and forgings.
90 Nmm
DL
Slim front section.
For measurements in confined spaces, at the base of grooves or
on recessed surfaces.
11 Nmm
E
Diamond ball indenter.
For measurements especially in the very high hardness range
(in excess of 50 HRC / 650 HV): Tool steels with high carbide
content inclusions.
11 Nmm
S
Ceramics ball indenter.
For measurements in the high hardness range (in excess of 50
HRC / 650 HV): Tool steels with high carbide content inclusions.
11 Nmm
C
Reduced impact energy.
Surface hardened components, coatings, thin walled or impact
sensitive components (small measuring indentation).
3 Nmm
DC
Short device.
For use in very confined spaces, e.g. in holes, cylinders or for
internal measurements on assembled machines.
11 Nmm
SVP
40
Wedge seating tester.
Semi-automatic device for the fast evaluation of the wedging
(seating and regularity) of stator windings.
28 Nmm

Note:
For Equotip 2 and Equotip 3 impact devices, the Equotip 3 indicating
device automatically recognizes the device type. When older impact devices are
connected, a selection menu pops up to allow the user to select the appropriate
device type.

Note:
The impact device DL can only be used with manual correction for impact
direction.
2.5. Testing procedure
• Press the on / off button
for approx. 2 seconds to switch on the device.
• Select “Bar graph” or “Basic mode” from the “View” menu (see section 5.1. “Views”).
• Select automatic compensation for impact direction (“a Automatic”) by pressing the F1 key
(see section 6.1. “Settings”). If “a” is not selectable, set the impact direction (
).
• Select the material group applicable to the tested sample by pressing the F2 key (see sec
tion 6.2. “Material groups”).
• Select the hardness scale to be displayed by pressing F3 (see 6.3. “Hardness scales”).
