30. y basis in harsh environment conditions Often the user doesn t have confidence in instrument operation and its accuracy Continuity of measurement leads presents additional problem Many times it is not possible to conclude the instrument state from ordinary measurement results Such results may look correct but in fact they are wrong due to the instrument malfunctioning Regular test instrument calibration with Eurocheck will reveal such problems Eurocheck doesn t provide a complete calibration solution for installation test instruments Regular 6 months or 1 year calibration of all measurement functions of the instrument is still recommended What it does provide is simple field calibration of the most frequently used functions when testing installations Furthermore in some countries it is obligatory for approved contractors to demonstrate trustworthy control system for ensuring accuracy of test instruments like NICEIC in United Kingdom Eurocheck represents one simple solution in such cases Notes a If in doubt about instrument operation and or its accuracy send it to your distributor or manufacturer for a complete calibration and service if required The same is valid if you re in doubt about Eurocheck operation a Installation measurements in general and typical applications are explained in Metrel handbook Measurements on electric installations in theory and practice CS 2099 Eurocheck Safety and operational considerations
