12 Apr Display range and measurement range – what is the difference?
The display range means all the features that may be displayed by the meter. However, every measurement may include some error caused by the measuring device. EN 61557 standard defines maximum error values for electrical measurements. Basing on this standard a measurement range of the instrument is defined to provide measurement results with an error lower than specified limits –this is called the measurement range. It should be noted that devices available in the European Union must have their measurement ranges specified on their cover casings, in accordance with EN-61 557.
