LMG Test Suite – CE compliance test software

August 29, 2014 // By Graham Prophet
LMG Test Suite tests in accordance with the currently valid version of EN 61000-3-2/-12 or EN 61000-3/-11 and also supports measurements according to ECE R-10.4 Annex 11 (that is, electromagnetic compatibility of vehicles). The software is available for download as free demo version or full version.

As a manufacturer of precision power measurement technology, ZES Zimmer is represented on international standards committees allowing it to enact changes and updates immediately in its test systems. Measurement results and the limit values (either fixed or product-specific) defined in the standards are also visualised graphically. Analysis can be carried out either online, while directly connected to the measurement hardware, or offline, using stored data records. Each data record is furnished with the basic characteristic data of the test sample (RMS values of voltage and current, active power, reactive power and apparent power, power factor, harmonic distortion, etc.) to increase the significance of the information and to avoid incorrect allocations.

The system is based on the ZES Zimmer's power analysis technology. A fast Ethernet interface (Gbit) provies smooth communication and data transfer between software and test hardware. The LMG Test Suite allows for quick identification of the cause of an inadequate test result. All measurements can be displayed and evaluated in the time domain alongside the familiar presentation in the frequency domain. All harmonic frequencies can be isolated throughout the test and investigated to assist with localising the problem. In addition, all data can be passed on to third-party applications in full resolution using the clipboard or file export for additional analysis.

The LMG Test Suite supports all AC power sources available on the market which fulfil the requirements of the CE standards to be tested. This provides maximum flexibility for users. In particular, they can continue to use the sources that are already available and thus avoid additional investments. Calibration of the AC power source specifically for the CE tests is not necessary, as the test system monitors compliance with the stipulated source parameters. For example, the system analyses the voltage harmonics and presents them graphically. This ensures freedom from distortion and voltage stability of the source.

All results are documented in test reports in PDF format. Alongside the
