    2.2. FUNCTIONS OF THE INSTRUMENT MX 535 installation tester is a portable measuring instruments with LCD display. It is powered by primary batteries or by recharge- able batteries, which it can recharge. This instrument is used to check the safety of electrical installations. It can be used to test a new installation before it is powered up, to check an existing installation, whether in operation or not, or to diagnose a malfunction in an installation.

    Function Press the key once to deactivate the audible signal emitted by the instrument. Press again to reactivate it. A sustained press serves to compensate the resistance of the leads. Press the key once to switch on the backlighting. Pressing it again switches it off. A long press on the key activates the Bluetooth link.

  • Page 11: Use

    3. USE 3.1. VOLTAGE MEASUREMENT 3.1.1. DESCRIPTION OF THE MEASUREMENT PRINCIPLE The device separates the alternating voltage from the direct voltage and compares the amplitudes to decide whether the signal is AC or DC. In the case of an AC signal, the frequency is measured and the instrument calculates and displays the RMS value of the signal (AC + DC).
  • Page 12 In the case of a live measurement (LOOP or RCD), the instrument shows where the phase should be on the outlet using the symbol. If the phase is on the wrong side, the symbol blinks to indicate that the tripod cable must be reversed. LOOP TEST SITE...

  • Page 13: Resistance And Continuity Measurement

    3.2. RESISTANCE AND CONTINUITY MEASUREMENT 3.2.1. DESCRIPTION OF THE MEASUREMENT PRINCIPLE For continuity measurements, the instrument generates a 200mA direct current between the + and COM terminals. It then measures the voltage present between these two terminals and from it deduces the value of R = V/I. For resistance measurements, the device generates a DC voltage between the + and COM terminals.
  • Page 14 3.2.3. VALIDATION OF THE MEASUREMENT The instrument then indicates whether or not the measured value is OK: „ If the measured value is less than the threshold (1Ω or 2Ω), the indicator lights and the instrument emits a continuous audible signal.

  • Page 16 3.3.3. VALIDATION OF THE MEASUREMENT If an alarm threshold is selected, the instrument informs you whether the measured value is OK or not: „ If the measured value is greater than the threshold, the indicator lights. „ If the measured value is below the threshold, the indicator lights.

  • Page 17: Earth Resistance Measurement

    3.4. 3P EARTH RESISTANCE MEASUREMENT This function is used to measure an earth resistance when the electrical installation to be tested is not live (new installation, for example). It uses two auxiliary rods, with the third rod being constituted by the earth electrode to be tested (whence the name “3P”). It can be used on an existing electrical installation, but the power must be cut off (main RCD).
  • Page 18 „ Press the TEST button to start the measurement. The instrument first displays - - - for several seconds. Ω  E-3P TEST TEST SITE Do not forget to reconnect the earth strap at the end of the measurement before powering the installation back up. 3.4.4.
  • Page 19 If the in-line configuration is not possible, you can plant the rods in a triangle. To validate the measurement, move the S rod on either side of the line HE. Avoid routing the connecting cables of the earth rods near or parallel to other cables (transmission or power supply), metal pipes, rails, or fences, this in order to avoid the risk of cross-talk with the measurement current.

  • Page 20: Loop Impedance Measurement

    3.5. LOOP IMPEDANCE MEASUREMENT In a TN or TT type installation, the loop impedance measurement is used to calculate the short-circuit current and to size the protections of the installation (fuses or RCDs), especially their breaking capacity. In a TT type installation, the loop impedance measurement makes it easy to determine the earth resistance without planting any rods and without cutting off power to the installation.
  • Page 21 „ The measurement starts automatically. The result is displayed: the loop impedance and the short-circuit current (Ik). „ Press the TEST key to return to voltage measurement. 3.5.3. MAKING A TRIP MODE MEASUREMENT  Press the LOOP key a second time to select the  LOOP function.
  • Page 22 3.5.4. ERROR INDICATION „ If the voltage measured between the L and PE terminals is not OK, in either amplitude or frequency, the symbol blinks. „ If, during the measurement, the fault voltage, U , is greater than the limit voltage, U , the measurement is aborted and the U symbol blinks.

  • Page 25 The instrument first of all checks that the voltage between the L and PE terminals is correct. If it is, the symbol lights steadily. If not, the symbol blinks and it is not possible to make a test. If there is a voltage on protection conductor PE, the instrument detects it and the indicator lights.

  • Page 27: Current Measurement

    3.7. CURRENT MEASUREMENT The MX 535 can make current measurements using a specific ammeter clamp, the optional MN73A. The MX 535 and MN73A clamp together can measure very low currents, of the order of a few mA, such as fault currents or leakage currents, and high currents, of the order of a few hundreds of amperes.
