  • Page 10: Test Procedure

    The brown test lead can be substituted by using the red remote test probe supplied. This allows remote activation of the MFT5000 from the safety of the test probe ensur- ing that you are always looking at the point of contact and not the MFT5000.
  • Page 11 The Socket & See MFT5000 is now correctly set up to perform continuity testing on a circuit. You can also set up your Socket & See MFT5000 to be used in Handsfree mode on continuity by simply pressing the 'Handsfree' button and then pressing test. Handsfree will flash at the top of the screen to indicate you are on Handsfree mode.

  • Page 12: Principle Of Measurement

    If the tester is connected to a live circuit (25V or greater), the LED will flash red and the hazard buzzer will sound. Your Socket & See MFT5000 is fully protected but measured RMS voltage will be displayed on the secondary/lower display. Further testing after this point will be inhibited.

To enable the Handsfree feature simply press the ‘Handsfree’ button once, The ‘Handsfree’ annunciator will appear flashing on the display and will continue to do so until cancelled by a further press of the 'Handsfree' button or by changing the function selector switch. When the ‘Handsfree’...
  • Page 15 Socket Testing The MFT5000 has a unique feature for testing sockets. Switch the Rotary Dial to socket, insert the 13A test leads BLUE, GREEN and BROWN into the tester terminals. Plug the 13AMP plug into the socket under test. If no voltage present the If voltage is present and wiring is above will be displayed.
  • Page 16 Polarity Test Pad Your Socket & See MFT5000 tester has a special polarity test function. It is a little known fact that a system can be reverse wired with Live (Phase) to earth/neutral and earth/neutral to Live (Phase) The sockets will all work and conventional loop testers will show and test that everything is correct despite this very dangerous wiring condition.

  • Page 17: Loop Impedance Testing

    Loop Impedance Testing Principle of Measurement BROWN GREEN (PE) T= 1/(2F) Hi-I Line-Earth Loop Measurement Place in several steps: a) The tester measures an unloaded half-cycle of the mains. b) The tester switches in load RL. This causes the main circuit to be slightly attenvated due to the e ective source impedance.
  • Page 18 Important note for calibration check box users: The smart loop test system used by the Socket & See MFT5000 is immune to sudden high value changes such as voltage spikes. As a result when changing calibration or check box loop values the tester or the supply must be switched o between changes of calibration values.

  • Page 19: Intermittent Operation

    The Socket & See MFT5000 Loop test function has 2 modes for Loop testing that allow the user to conduct the most accurate test possible whether or not the circuit under test is protected by an RCD. Intermittent Operation The Socket & See MFT5000 is designed for a large number of loop tests in rapid succession.
  • Page 20 Unlike most testers that only measure the resistance of the Loop, the high current mode of the Socket & See MFT5000 will measure the impedance of the Loop which includes an element of reactance. This can be significant where the distribution board is close to the mains supply transformer and is therefore much more accurate than older Loop testing techniques.
  • Page 21 This will reduce the chances of the RCD tripping as a result of combined leakages. PFC/PSC In both Loop test mode the Socket & See MFT5000 will also display the supply voltage and at the touch of the PFC button the PFC/PSC depending on being connected L-E or L-N will be displayed.
  • Page 22 High Current Test (Ze) The high current should only be conducted with the distribution board test lead set Socket & See SOC/DLMPROLEAD configured in 2 wire mode. Do not use this function with the Socket & See mains lead SOC/DLMPROLEAD or the distribution lead set in 3-wire configuration.
  • Page 23 The brown test lead can be substituted by using the red remote test probe supplied. This allows remote activation of the MFT5000 from the safety of the test probe ensuring that you are always looking at the point of contact and not the MFT5000.
  • Page 24 The result of the test will be shown in the primary display. A single press of the PFC/Loop button will toggle the display so that the PFC is shown in the primary display and the impedance in the secondary display. A further press will toggle the results between the primary and secondary displays.
  • Page 25 Warning Leakage currents in the circuit following the residual current protection device may influence the measurements. Potential fields of other earthing installations may influence the measurement. Special conditions in S-type residual current protective devices shall be taken into consideration. Equipment connected downstream of a residual current protective device (RCD) may cause considerable extension of the operating time.
  • Page 26 0° and 180° this means that four tests (or for 30mA RCD’s six tests) have to be made for each RCD. The user friendly design of the Socket & See MFT5000 simplifies the test process by enabling you to do any of these tests by making just two function selections.
  • Page 27 The Socket & See MFT5000 takes care of this for you by alternating the start point of consecutive tests at any given setting. If for example you have selected a test at the rated trip current (x1) of a 100mA RCD, the first press of the test button will apply a...
  • Page 28 Pass or Fail Result In addition to displaying the time taken for the RCD to trip the Socket & See MFT5000 will also indicate whether it has passed or failed the test requirement of BS 7671.
  • Page 29 This option is not available or required for other ratings. Ramp Test The Socket & See MFT5000 also includes a diagnostic Ramp test feature. In this mode rather than applying a steady fault current and measuring the time taken for the RCD to trip, the Socket &...
