NMi (Netherlands) - The use of measuring instruments for custody transfer purposes is generally subject to regulations worldwide. These regulations tend to be based on the IEC, EN or OIML standards and recommendations. The immunity EMC (Electromagnetic Compatibility) rules form an important part of the type examination of measuring instruments. This course is designed to provide you with a good insight of the specific metrological EMC requirements, interpretations and solutions that apply with these tests.

Object:
All electronic devices are subject to a set of EMC requirements, whether they are measuring instruments for consumer usage (such as kWh meters, taxi meters, retail weighing instruments and fuel dispensers) or industrial measuring instruments such as flow computers, automatic weighing instruments and flow meters.

On completion of this training course you will be better prepared for the type of testing that your measuring instrument must undergo and for the certification requirements that apply during the metrological EMC testing.

During the course, you will be apprised of all current and future EMC requirements. Taking these factors into account in the earliest stages of the design and development phase can reduce time and money and involve fewer retests in getting your product to market.

Our extensive experience in the area of testing and certification has taught us that metrological EMC testing, where the accurate measurement of the instrument is taken into account, represents one of the most critical tests in the certification process. Designers sometimes make the mistake of confusing generic EMC requirements (as required under the EMC directive) with the metrological EMC requirements that are currently in force. If any device fails to measure precisely during the testing process in our lab due to the effects of electromagnetic radiation, the design will have to be modified and retested. This can be wasteful and time-consuming. After all, it is your objective as well as ours to ensure that you receive your certification as quickly and as efficiently as possible. This training course will greatly increase your prospects in this regard.
