5 Measuring Process

5.1 Measuring Procedure

Preferably perform measurements at temperatures between

10 °C and 50 °C only.

The items in (brackets) are illustrated in Fig. 5.4. 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 you are going to evaluate.

• Enter the basic settings as described under ”Settings”.

• Use a grindstone to smoothen the test surface.

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!

• Position the concrete test hammer perpendicular to the

test surface.

• Deploy the impact plunger (1) by pushing the concrete

test hammer towards the test surface until the

pushbutton (6)

springs out.

Danger!

Always hold the concrete test hammer in both hands, perpendicular to the

test surface, 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 20mm apart.

• Position the concrete test hammer perpendicular to and

against the test surface. Push the concrete test

hammer against the test surface at moderate speed

until the impact is triggered (a high beep acknowledges

registration).

• Repeat this procedure for the whole measurement

series.
