Page 15: Line Impedance Calibration
CS 2099 Eurocheck Eurocheck operation Selected IΔn current will affect dissipation of measurement results. Lower IΔn currents (especially 10 mA) will cause larger variations in results. Consider accuracy of trip-lock function when evaluating calibration results (accuracy is defined in User manual of your instrument). 4.7 Line impedance calibration Line impedance is measured between L and N conductors. -

CS 2099 Eurocheck Eurocheck operation 4.8 RCD trip-out time calibration Eurocheck simulates an RCD with IΔn of 30 mA and trip-out time of 50 ms. Trip-out time calibration will not trip an RCD if it’s present in installation where Eurocheck is connected, regardless of selected IΔn current. -
Page 17: Rcd Measuring Current Iδn=30 Ma Verification
It is essential that the test instrument measuring current is within certain limits. For example, standard EN 61557 defines low limit as IΔn – 0 %, and high limit as IΔn + 20 %. Metrel test instruments has even narrower specification, high limit is defined as IΔn + 10 %. -
Page 18: Lowω And Continuity Resistance Calibration
– 0 Ω (short-circuited test leads). Metrel installation test instruments usually offer 2 distinctive functions for measuring low resistances. LowΩ usually stands for measuring low resistances with 200 mA test current, often with automatic polarity reversal. Continuity denotes a function with lower measuring current, usually around 7 mA. - Page 19 Notes: Most Metrel installation test instruments use L and N measuring leads of universal test cable to perform low resistance measurements. However, there are exceptions to this rule like MI 3101 – EurotestAT, which uses N and PE leads.

CS 2099 Eurocheck Eurocheck operation Insulation of measurement leads Insulation of measurement leads may deteriorate over time. This can cause measurement and/or safety related problems. If insulation material leaks current measured results will be wrong. Also in such case there is a risk of electric shock when the user touches deteriorated part of insulation. -
