3.2 Preparation and use
Connect the two probe heads, which can be used either as emitter or receiver to the
connectors marked EMITTER (E) and RECEIVER (R) using the cables supplied with
the instrument.
WARNING:
High voltage (at very low Energy) is present in the EMITTER connector of the
instrument, the cable must be connected before switching on the instrument. This voltage
could be dangerous for the user. Also ensure that the cables are not damaged.
Switch on the instrument via the ENTER button; the display will show:

To make readings, a thin layer of contact paste should be spread on both probe heads,
and/or on the face of the concrete under examination, and then they are placed on the
concrete. A small pressure should be applied to the probe heads, the varying of which will
show small variations of the transit time displayed on the instrument (if the applied
pressure is high, the transit time decreases slightly). The value shown on the display is the
transit time of the ultrasonic waves through the concrete from the transmitter to the
receiver expressed in micro-seconds.
