Gently press straight down on the transducer body slightly until the diamond pyramid makes
initial contact with the surface of your part. Using a little more force, increase the downward pressure
immediately until the diamond pyramid is forced into the surface
. (The Blinking Transducer light will now
stay on constantly showing that you are making a good connection to the part)
.
The effort should be made smoothly.
Be sure that your hand does not shake because the
transducer body must remain stable during the test. For the proper transducer operation, it is necessary
to apply an effort of not less than 14.7 N (1.5 kgf) to its body and keep it stable during the process of
measurement. Do not be afraid to apply an excessive effort to the transducer body as it will be limited
by the built-in stop.
DO NOT JAM PROBE ONTO ANY SURFACE!
•
Keep constant pressure on the transducer body during 3-4 seconds. ‘Transducer’ symbol on the
display will stop blinking.
•
After the sound signal and appearance of the hardness value on the electronic transducer
display, stop holding pressure on the transducer body. The ‘transducer’ symbol on the display will start
blinking again, and the transducer body will return to the initial position.
The first measurement has been completed, and the hardness tester is ready for the next measurement.
Experimental Measurement
It is advisable to consider the first measurement as experimental measurement. In order to acquire some experience of how
to use the transducer, it is recommended to conduct a number of experimental measurements.
Acquiring some experience working with the transducer
To acquire some experience of working with the transducer, it is recommended to use reference hardness blocks. Measure
the hardness of a reference hardness block (not less than 10-20 measurements) and compute its mean value. If the
obtained value does not correspond to the number of the reference hardness block, conduct more measurements.
If the hardness tester readings are stable and the obtained mean value corresponds to the reference hardness blocks rated
value you can begin testing your particular application.
In the process of working with the transducer, make sure that the cable (connecting the transducer with the electronic
module) is not twisted.
Using the D1 Dynamic Transducer
(Impact device “D”)
Be sure that the requirements for the tested article are observed, connect the transducer to the
electronic module switch the power supply on and turn to the ‘measurement’ mode
In the process of measurement, the article shall be fixed and the transducer shall be installed
perpendicular to the measurement area.
