Note: Eurocheck powers on automatically 2 seconds after it is connected to the mains supply. It checks for correct mains supply plug orientation during power up. If the orientation is wrong “incorrect polarity” LED lights. In such case reverse connection of power supply cord.

CS 2099 Eurocheck Eurocheck operation 4 Eurocheck operation 4.1 Recommended calibration sequence and practice This chapter lists recommended sequence for calibration of installation test instruments. It is not obligatory to follow this sequence. Eurocheck offers additional calibration functions (all functions are explained in detail in the following chapters). Calibration using universal test cable Step Calibrated function Purpose 1 LowΩ Determination of measurement accuracy.
CS 2099 Eurocheck Eurocheck operation 4.2 Sample test report form Caution: This sample test report form is suitable for Metrel installation test instruments like MI3100 – EurotestEASI. It could be easily modified to suit other types of instruments. q It is not based on any regulation or recommendation.
CS 2099 Eurocheck Eurocheck operation 4.3 Selecting calibration function/sub-function The following measurements can be selected with the RCD/LOOP function selection button (see Figure 3.1). Appropriate LED lights when particular function/sub-function is selected: q Fault loop and trip-lock impedance calibration (two impedance values available), q RCD trip-out time calibration and instrument test current verification. The following measurements are not indicated with LEDs on front panel.
CS 2099 Eurocheck Eurocheck operation 4.5 Fault loop impedance calibration Fault loop impedance is measured between L and PE conductors. Fault loop calibration will not trip an RCD if it’s present in installation where Eurocheck is connected, regardless of selected IΔn current. Caution: q q When performing fault loop impedance calibration Eurocheck connects fault loop calibration output to mains line impedance (L and N, important when evaluating calibration measurement results).
CS 2099 Eurocheck Eurocheck operation Note: q In some instruments the function is named “Fault loop resistance”; however the calibration procedure is the same. Figure 4.1: Performing fault loop impedance calibration using plug cable L PE N Figure 4.
CS 2099 Eurocheck Eurocheck operation 4.6 Trip-lock impedance calibration Fault loop impedance is measured between L and PE conductors. Trip-lock calibration will not trip an RCD if it’s present in installation where Eurocheck is connected, regardless of selected IΔn current. Caution: q q When performing fault loop impedance calibration Eurocheck connects fault loop calibration output to mains line impedance (L and N, important when evaluating calibration measurement results).
CS 2099 Eurocheck q 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. Caution: q Pay special attention when selecting appropriate IΔn current. It should be set to 30 mA, and multiplier should be set to x1. Otherwise the reading of trip-out time may be wrong.
CS 2099 Eurocheck Eurocheck operation 4.9 RCD measuring current IΔn=30 mA verification This test is part of RCD trip-out time calibration and couldn’t be performed separately – it is valid only for IΔn = 30 mA. Refer to chapter 4.8 for more information. 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 %.

CS 2099 Eurocheck Eurocheck operation 4.12 Voltage and frequency calibration Eurocheck offers a.c. voltage source of 50 V (at 240 V mains voltage). This source can be used for voltage and frequency calibration. It is possible (and recommended) to include second value into your calibration procedure – 0 V (short-circuited test leads, not open). Frequency is equal to mains and is usually very close to 50 Hz or 60 Hz.

Refer to chapter 4.12 for more information.
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. Eurocheck is not needed to perform this test.
