Measuring Process
5.1
Measuring Procedure
Preferably do perform measurements at tem-
peratures between 10 °C and 50 °C only.
The items in (brackets) are illustrated in Fig. 5.4, page 11.
Perform test impacts with the concrete test hammer on a
smooth, hard surface, without the cable connected to the
display unit, before taking any measurements which you
are going to evaluate.
Fig. 5.1
Preparing the test surface
Warning!
The impact plunger (1) generates a recoil
when it deploys. Always hold the concrete test
hammer in both hands!
Fig. 5.2
Deploying the impact plunger (1)
Danger!
Always hold the concrete test hammer in
both hands, perpendicular to the test sur-
face, before you trigger the impact!
Each test surface should be tested with at
least 10 impacts.
The individual impact points must be spaced at
least 20 mm apart.

Performing the
test
• Enter the basic settings as
described under ”Settings”,
page 6.
• Use a grindstone to smoothen
the test surface.
• Position the concrete test ham-
mer perpendicular to the test
surface.
• Deploy the impact plunger (1)
by pushing the concrete test
hammer towards the test sur-
face until the pushbutton (6)
springs out.
• Position the concrete test ham-
mer perpendicular to and
against the test surface. Push
the concrete test hammer
against the test surface at mo-
derate speed until the impact is
triggered (a high beep acknow-
ledges registration).
• Repeat this procedure for the
whole measurement series.
