IMPORTANT NOTE

Our devices, units and accessories are designed, constructed and finished according to the state of the art. We presume that our customers similarly have knowledge of the art in respect of the restrictions in the completeness or reliability of the test process resulting therefrom. We are pleased to give full explanations where customers are in doubt. Our products are subjected to an acceptance test according to specified technical data. The release of equipment is incumbent on specialized personnel. We accept responsibility for malfunctions or defects as specified under our general terms of delivery. Our products are also used for the non-destructive testing of working materials in parts, the failure of which can represent a high risk. This applies, for example, both to working materials or component parts for the automobile industry and to the aviation or nuclear power fields. The user needs to undertake all reasonable measures to avoid workpieces from passing unnoticed. Observation units on the test units for this purpose are offered. The risk of a malfunction of the unit can be reduced by regular checks of the device, accessories, test media, operating conditions and test personnel. In particularly important cases a check needs to be carried out both before and after each test. Such checks lead to the discovery of not only systematical malfunctions but malfunctions of the system and the device occurring sporadically. When the malfunctions in function have been ascertained, then measures must be taken without delay to prevent the construction parts, which were established in the last check as perfect, from being further used without reexamination. We are ready to discuss the type and scope of checking or organisation measures prior to acceptance of the test procedure.

11.1

What you should know prior to startingPassing-on, availability and storage of this handbook

This handbook is a standard accessory and comes with the ECHOMETER 1073 when delivered. Please make sure that this handbook is passed to the quality assurance dept. of your company from where it can be ... handed on to the specific user. Please store this handbook like a document. Copies of this manual can be ordered from KARL DEUTSCH.1.2 Notes on this handbook

This manual deals with the proper use of the Ultrasonic Thickness Gauge Economy-ECHOMETER 1073. Notes marked with the symbol must be read and considered in order not to reduce the quality of the test process and, where appropriate, not to neglect safety-relevant aspects. Supplementary notes worth knowing can be recognized by the information symbol At the end of this manual a folder sheet with reference numbers is included. Subassemblies described in text or mentioned are provided with the corresponding reference numbers in order to allow an easy assignment.

1.3

Requirements concerning the test personnel

To operate the ECHOMETER according to the demands of the corresponding test task, the user of the ultrasonic thickness gauge should be able to read and understand this manual. Moreover, there should be a basic knowledge of methods used in the application of measurement technique; thus the operator can judge objectively the measured values and their tolerance. By this, the possibility to recognize systematic or applicational malfunctions can be increased as well as the recognition of error caused by the gauge. By means of periodically executed check measurements using comparable test pieces with known thickness you can verify the correct function of the test system. In addition, the test personnel should be familiar with processes to be executed in the case of instrumental malfunction or error.1.4 Safety noteThe ECHOMETER 1073 must not be used in an explosive environment (e.g. in mining areas, in tanks with explosive gas mixtures etc.). Observe the respective safety rules.

1.5

Intended use

The ECHOMETER 1073 is a gauge to measure thickness of sound-conductive materials. The correct handling of the gauge is described in this manual. Section 1.6 of this manual deals with the gauge-specific properties and requirements for the intended use. If accessory is required for the intended use, only gauge-specific KARL DEUTSCH accessory or accessory expressively approved by KARL DEUTSCH may be employed.

Measuring range of probes, display resolution and unit, measuring tolerance

The ECHOMETER works with dual element (TR or SE) probes. Dual element (TR) probes have separate transmitter (T) and receiver (R) elements, which must be connected to the respective transmitter output and receiver input of the thickness gauge. ECHOMETER probes are equipped with fixed twin cables of approx. 1 m length and Lemo type connectors. Corresponding probe connectors and instrument sockets have colored marks to assure proper assign
