PROFITEST MF Series PROFITEST MF XTRA, MF TECH IEC 60364-6, EN 50110-1 • • Testing of residual current devices (RCCBs) Measurement of touch voltage without tripping the RCCB Touch voltage is measured with reference to nominal residual current using ⅓ of the nominal residual current value. Testing for N-PE reversal Tripping test with nominal residual current, measurement of time to trip Testing of equipment and RCCBs with rising residual current including indication of tripping current and touch voltage Testing of RCCBS with the following nominal current values: ½ × IN, 1 × IN, 2 × IN, 5 × IN to 300 mA Intelligent ramp (PROFITEST MF XTRA only): simultaneous measurement of breaking current IN and breaking time tA Testing of selective S SRCDs, PRCDs (SCHUKOMAT, SIDOS or comparable), type G/R, type AC, types A and F, types B and B+ and type EV Testing of RCCBs which are suitable for pulsating residual direct current – testing is conducted with positive or negative half-waves. Creation of test sequences (IZYTRONIQ) Intelligent data transmission Simulation of operating states of electric vehicles at charging stations with adapter Large Voltage and Frequency Ranges A broad-range measuring device permits use of the test instrument in all alternating and 3-phase electrical systems with voltages from 65 to 500 V and frequencies of 16 to 400 Hz. Loop and Line Impedance Measurement Measurement of loop and line impedance can be performed in the 65 to 500 V range. Conversion to short-circuit current is based on the respective nominal line voltage, insofar as the measured line voltage is within the specified range. Test instrument measuring error is also taken into account for conversion. Outside of this range, short-circuit current is calculated on the basis of momentary line voltage and measured impedance. Insulation Resistance Measurement Using Nominal Voltage, with Variable or Rising Test Voltage Insulation resistance is usually measured with a nominal voltage of 500, 250 or 100 V. A test voltage which deviates from nominal voltage, and lies within a range of 20/50 to 1000 V, can be selected for measurements at sensitive components, as well as systems with voltage limiting devices. Measurement can be performed with a constantly rising test voltage in order to detect weak points in the insulation and determine tripping voltage for voltage limiting devices. Voltage at the device under test and any triggering/breakdown voltage appear at the test instrument’s display. Standing-Surface Insulation Measurement Standing-surface insulation measurement is performed with momentary line frequency and line voltage. Gossen Metrawatt GmbH Low-Resistance Measurement Bonding conductor resistance and protective conductor resistance can be measured with a test current of  200 mA DC, automatic polarity reversal of the test voltage and selectable current flow direction. If the adjustable limit value is exceeded, an LED lights up. Earthing Resistance Measurement In addition to measurement of the overall resistance of an earthing system, selective measurement of the earthing resistance of an individual earth electrode is also possible, without having to disconnect it from the earthing system. A current clamp sensor available as an accessory is utilized to this end. Moreover, PROFITEST MF XTRA allows for battery-powered „battery operation“ earth resistance measurements: 3-/4-pole and earth loop resistance measurements. Universal Connector System The interchangeable plug inserts and 2-pole plug-in adapter – which can be expanded to 3-poles for phase sequence testing – allows for use of the test instrument all over the world. Special Features • Display of approved fuse types for electrical systems Energy meter start-up testing Measurement of biasing, leakage and circulating current of up to 1 A, as well as working current of up to 1000 A with current clamp sensor (available as an accessory)

Display with Selectable Language Menus, setting options, measurement results, tables, notes and error messages as well as schematic diagrams appear at the LCD. The display can be set to the desired language depending on the country in which the test instrument is used: D, GB, I, F, E, P, NL, S, N, FIN, CZ or PL. Operation Device functions are selected directly with the help of a rotary selector knob. Softkeys allow for convenient selection of subfunctions and parameter settings. Unavailable functions and parameters are automatically prevented from appearing at the display. The start and RCD tripping...
