First, probes are installed on the 1-2 point scheme (crack is in the
middle, ie l = 2x), and the time t
1
, then the probes are installed at the
point of 3-4 (crack - in the middle l = 4x), time is measured t
2
and
when you press the function key "SAVE"
the depth of the
crack calculates automatically.
8.5.4. If after the change of area on the tested object speeds
significantly different from each other, it is necessary to verify the
compliance of the installation base of measurement and quality of
acoustic coupling of the "probe-object", defects in the concrete and
reinforcement effect.
9. Technical maintenance, special conditions of operation
9.1 On the whole, Ultrasonic Tester of Building Materials Strength
do not require any special maintenance. However, for the purpose of
device stable operation, regular maintenance is advisable.
9.2. Probe maintenance
Clean probes from dust, mud and oil traces. Use soft cloth
impregnated with alcohol solution.
9.3. Information processing unit maintenance
To clean from any pollution, use soft dry cloth. Do not use the water,
since the device is neither spray-proof nor water-proof due to the
joints on its body.
Do not use any solvents, they can damage indication signs and
writings on the front and back sides of the body.
9.4. Battery maintenance
The battery average life is not less than 3 years. The battery used in
compliance with the "C" or "AA" international standard. It is done for
