11. In the case of a measurement at high current 200 mA at the end of one second the device reverses the direction of the current and makes another measurement for one second The result displayed is the mean of these two measurements It is possible to make measurements with either the positive or the negative polarity of the current disabled For measurements at low current 12 mA or kQ the polarity is positive only 3 2 2 MAKING A MEASUREMENT To comply with standard IEC 61557 the measurements must be made at 200 mA The reversal of the current serves to compen sate for any residual electromotive forces and more important to check that the continuity is in fact duplex When you make continuity measurements that are not contractual prefer a current of 12 mA Even though the results cannot be regarded as those of a normative test this significantly increases the life of the device between charges and forestalls untimely tripping of the installations if there is a connection error The permanent mode is used to chain measurements without having to press the TEST button each time If the object to be measured is permanent it is better to switch to pulse mode and make a measurement at positive polarity then a measurement at negative polarity manually in order to leave time for the measurement to settle The alarm if activated serves to report by an audible signal that the measurement is below threshold making it unnecessary to look at

TN or TT type installation the loop impedance measurement also makes it possible to calculate the short circuit current and size the protections of the installation fuse or circuit breaker This measurement cannot be made in an IT type installation because of the high earthing impedance of the supply transformer which may even be completely isolated from earth 3 5 1 DESCRIPTION OF THE MEASUREMENT PRINCIPLE The device starts by generating pulses having a duration of 300 us and an amplitude of at most 5 A between the L and N terminals This first measurement is used to determine ZL It then applies a low current 6 9 or 12 mA at the user s discretion between the L and PE terminals This low current serves to avoid tripping residual current devices of which the nominal current is greater than or equal to 30 mA This second measurement is used to determine Z The device then calculates loop resistance Z Z_ Z Z and short circuit current Ik U Z PE The value of Ik serves to check the proper sizing of the circuit breaker For greater accuracy it is possible to measure Z with a high current TRIP mode but this measurement may trip out the instal lation 3 5 2 MAKING A MEASUREMENT Connect the measuring cable to the device then to the socket outlet of the instal At the time of connection the device first checks that the voltages present on its terminals are correct then determines the position of the phase L
15. When the RCD opens the circuit the device displays the exact value of the tripping current and the trip time This time is an indication and may differ from the trip time in pulse mode which is closer to the operational reality m For the pulse mode test the device generates a sinusoidal current at the mains frequency having an amplitude of I 2 or 5 between the L and PE terminals lasting at most 500 ms And it measures the time the circuit breaker takes to open the circuit This time must be less than 500 ms m For the non tripping test the device generates a current of 0 5 I for one or two seconds depending on what the user has programmed Normally the circuit breaker must not open the circuit In all cases if the circuit breaker does not trip out the device then sends a current pulse between the L and N terminals If the circuit opens it means that the circuit breaker was incorrectly installed N and PE reversed 3 9 2 PERFORMING A TEST IN RAMP MODE Connect the measuring cable to the device then to a socket outlet included in the circuit Set the switch to RCD s L protected by the circuit breaker to be tested At the time of connection the device detects the positions of the phase L and of neutral N with respect to the protective conductor PE and displays them If 9 L necessary it then automatically switches the L and N terminals so that the test can be done without modifying the connections of the termin
