Must-read for experimental operation of concrete dynamometer
During the experiment, the instrument and test block should be placed on a solid platform, and it is best to place a rubber pad under the test block.
Place the transmitting probe at the middle position on the side of the test block, and place the receiving probe at the same end of the transmitting probe from the edge. At the same time, the probe should reach the middle of the height of the test block.
After placing the probe, first press the transmitting probe firmly, then adjust the instrument to the manual state, and then adjust the resonant frequency on the display appropriately to make it the same or similar to the frequency of the test block, and then adjust the receiving probe appropriately. The distance relationship with the test block. At this time, the graphics on the oscilloscope will change, and the last two digits on the display will also change. At this time, place the receiving probe at the position where the graphics is the largest or the amplitude value is the largest, then the probe is in good contact.
Do not change the parameters in the instrument at will (except weight, time, date), otherwise it will affect the experimental results.
The environment where the instrument is located must be dry to prevent electronic components from getting damp and affecting their lifespan.
