Dynamic testing instruments for construction use made by our company have achieved great progress with your help. Great changes have occurred on both the instrument appearance and the kernel. The hardware technology ranks a first-class level in the domestic market, with market share of over 80%. All of these owe to your great support and active feedback.

On the basis of original internal information, we introduce some external documents and references and try to make the instruction information as sufficient as possible so that every user could find applicable part.

The instruction addresses directions for use of RS-1616K(P), RS-1616K(S) and RS-1616W(L) dynamic testing instruments. It consists of foundation pile testing (incl. Acquisition of both large and small strain signals, rough field analysis of built-in softwares), wave velocity testing and preliminary analysis of some built-in softwares, and micro-tremor testing and preliminary analysis of some built-in softwares. The instruction is recompiled and rearranged, so there may be inaccurate words. We would be very appreciated if you find any errors and provide positive correction. Besides, if some primary users fail to well understand expressions in the instruction, welcome to call or contact us by the following ways so that we could use more understandable expressions and edit this instruction well together.
