Measuring device ZVUK 203M

Measurement procedure

1. After switching on the device, use the buttons to enter the default parameters which are necessary for evaluating the measurement results:
   • Total measurement time [ms]
   • Delay in receiving and evaluating the signal [ms]
   • Coefficient of the product´s shape
   • Type of bond
   • Type of the basic material (for vitrified products)
   • Specific weight or dimensions and weight
   • The appropriate frequency range, where the device will search an optimized natural frequency of oscillations in the measured product
2. The measured product must be placed on a suitable surface which will not muffle the forced vibrations.
3. During the measuring process, the device must be held at a minimum distance from the product, and in a suitable position with the microphone in its direction.
4. By a gentle hammer blow on the measured product, oscillating movements will be triggered.
5. The device will do the measuring in a matter of seconds and the result will be shown on the display.
6. If we need to store more measured results for further processing, it is necessary to connect the device to a PC.
