These can then be edited in ETC and transferred back to the test instrument if required. 3h OFFSET RL-PE / RN-PE / RL-N For the measurement of ZL-PE, ZL-N, RE and ∆U(ZLN), ohmic offset values RL-PE, RN-PE and RL-N can be ascertained here, which then appear in the footers of the corresponding measuring menu pages and are subtracted from the measured values.
Measurement of Touch Voltage via Finger Contact 5.3 When a measurement is started and if you touch the ON/START key with your finger, the test instrument detects whether or not dangerous touch voltage Ub is present at the PE terminal relative to ground.
5.5 Help Function The following information can be displayed for each switch position and basic function after it has been selected with the rotary selector switch: • Wiring diagram • Measuring range • Nominal range of use and measuring uncertainty • Nominal value ➭ Press the HELP key in order to query online help. ➭ If several pages of help are available for the respective measuring function, the HELP key must be pressed repeatedly. ➭ Press the ESC key in order to exit online help. 5.
5.7 Freely Selectable Parameter Settings or Limit Values In addition to fixed values, other values can be freely selected within predefined limits for certain parameters, if the symbol for the EDIT menu (3) appears at the end of the list of setting values. Freely Selecting a Limit Value or Nominal Voltage Select editable value. Select editable value. 3 4 5.
6 Measuring Voltage and Frequency 6.1.2 Voltage Between L – PE, N – PE and L – L with 2-Pole Connection Select the Measuring Function Press the softkey shown at the left in order to switch back and forth between the country-specific measuring adapter, e.g. PRO-Schuko measuring adapter (Z503K), and 2-pole measurement with the KSPROFITEST INTRO (Z503L). The selected connection type is displayed inversely (white on black).
6.2 3-Phase Measurement (line-to-line voltage) and Phase Sequence 7 Testing RCDs Testing of residual current devices (RCDs) includes: • Visual inspection • Testing • Measurement Use the test instrument for testing and measurement. Connection The included measurement cables (Z503L) are required in order to connect the instrument.
Test Standard 7.1 The following must be substantiated per DIN VDE 0100-600:2008: – Touch voltage occurring at nominal residual current may not exceed the maximum allowable value for the system. – Tripping of the RCCB must occur within 400 ms (1000 ms for selective RCDs) at nominal residual current.
1) Measuring Touch Current Without Tripping the RCD 2) Tripping Test after the Measurement of Touch Voltage Measuring Method ➭ Press the I∆N key The instrument uses a measuring current of only ⅓ nominal residual current for the determination of touch voltage UI∆N which occurs at nominal residual current. This prevents tripping of the RCCB. This measuring method is especially advantageous, because touch voltage can be measured quickly and easily at any electrical outlet without tripping the RCCB.
7.2 Special Tests for Systems and RCDs 7.2.1 Testing Systems and RCCBs with Rising Residual Current (AC) for Type AC, A/F, B/B+ and EV, MI RCDs Touch voltage: Measuring Method The instrument generates a continuously rising residual current of (0.3 ... 1.3) • I∆N within the system for the testing of RCDs. The instrument stores the touch voltage and tripping current values which were measured at the moment tripping of the RCCB occurred, and displays them.
Testing RCCBS with 5 • I∆N 7.2.3 Measurement of time to trip is performed here with 5 times nominal residual current. Note Measurements performed with 5 times nominal fault current are required for testing type S and G RCCBs in the manufacturing process. They are used for personal safety as well. 7.2.4 Testing of RCCBs Pulsating DC Residual Current In this case, RCCBs can be tested with either positive or negative half-waves. The standard calls for tripping at 1.4 times nominal current.
7.3 Testing of Special RCDs 7.3.1 Systems with Type RCD-S Selective RCCBs Selective RCCBs are used in systems which include two series connected RCCBs that are not tripped simultaneously in the event of a fault. These selective RCCBs demonstrate delayed response characteristics and are identified with the S symbol. Measuring Method The same measuring method is used as for standard RCCBs (see sections 7.1 on page 18 and 7.2.1 on page 20).
Measuring Method 7.3.3 The following can be measured, depending upon the measuring method: • Time to trip tA: tripping test with nominal residual current I∆N (the PRCD-K must be tripped at 50% nominal current). • Tripping current I∆ for testing with rising residual current IF RCCBs from the SCHUKOMAT SIDOS series, as well as others which are of identical electrical design, must be tested after selecting the corresponding parameter. Monitoring of the PE conductor is performed for RCDs of this type.
7.3.4 Type G or R RCCB Set the Parameter – 5 Times Nominal Current In addition to standard RCCBs and selective RCDs, the special characteristics of the type G RCCB can also be tested with the test instrument. The type G RCCB is an Austrian specialty and complies with the ÖVE/ÖNORM E 8601 device standard. Erroneous tripping is minimized thanks to its greater current carrying capacity and shortterm delay.
8 Testing of Breaking Requirements for Overcurrent Protective Devices, Measurement of Loop Impedance and Determination of Short-Circuit Current (functions ZL-PE and IK) Select the Measuring Function ZL-PE Testing of overcurrent protective devices includes visual inspection and measurement. Use the PROFITEST INTRO to perform measurements.
8.1 Measurements with Suppression of RCD Tripping 8.1.1 Measurement with Positive Half-Waves Measurement by means of half-waves plus direct current makes it possible to measure loop impedance in systems which are equipped with RCCBs.
Special Case: Suppressing Display of the Limit Value The limit value cannot be ascertained. The inspector is prompted to evaluate the measured values himself, and to acknowledge or reject them with the help of the softkeys. Measurement passed: ✔ key Measurement failed: X key The measured value can only be saved after it has been evaluated.
Measurement Cable Compensation The resistance of the respectively connected measurement cable or the country-specific measuring adapter must be compensated for each line impedance measurement, i.e. it must be subtracted from the measurement results as an offset. Proceed as described in section 4.5 under „OFFSET RL-PE / RN-PE / RL-N“ on page 12 to this end in order to ascertain offset values RLPE-OFFSET and RNPE-OFFSET Polarity selection Start Measurement Semiautomatic measurement See also section 5.
10 Earthing Resistance Measurement (RE function) Earthing resistance RE is important for automatic shutdown in system segments. It must have a low value in order to assure that high short-circuit current flows and the system is shut down reliably by the RCCB in the event of a fault. Test Setup Earthing resistance (RE) is the sum of the earth electrode’s dissipation resistance and earth conductor resistance.

Measurement Cable Compensation The resistance of the respectively connected measurement cable or the country-specific measuring adapter must be compensated for each earth resistance measurement, i.e. it must be subtracted from the measurement results as an offset. Proceed as described in section 4.5 under „OFFSET RL-PE / RN-PE / RL-N“ on page 12 to this end in order to ascertain offset values RLPE-OFFSET and RNPE-OFFSET.
11 ! Measurement of Insulation Resistance Polarity Selection 2-pole measurement (selection relevant for report generating only), measurements between: Lx-PE / N-PE / L+N-PE / Lx-N / Lx-Ly / AUTO* where x, y = 1, 2, 3 Attention! Insulation resistance can only be measured at voltagefree objects. * AUTO parameter (see section 5.8) 11.
The constant test voltage function offers two options: • After briefly pressing the ON/START key, specified test voltage UN is read out and insulation resistance RINS is measured. As soon as the measured value is stable (settling time may be several seconds in the case of high cable capacitance values), measurement is ended and the last measured values for RINS and UINS are displayed. U is the voltage which is measured at the test probes during and after testing.
Special Condition for Insulation Resistance Measurement ! Set Parameters Attention! Test voltage: 50 V / 100 V / 250 V / 325 V / 500 V / 1000 V* Insulation resistance can only be measured at voltagefree objects. If measured insulation resistance is less than the selected limit value, the LIMIT LED lights up. If an interference voltage of ≥ 25 V is present within the system, insulation resistance is not measured. The MAINS/NETZ LED lights up and the “interference voltage” pop-up message appears.
12 Measuring Low-Value Resistance up to 200 Ohm (protective conductor and equipotential bonding conductor) According to the regulations, the measurement of low-value resistance at protective conductors, earth conductors and bonding conductors must be performed with (automatic) polarity reversal of the test voltage, or with current flow in one direction (+ pole to PE) and then the other (– pole an PE).
12.1 Measurement with Constant Test Current Start Measurement Press and hold for longterm measurement ! Attention! The test probes should always be in contact with the DUT before the ON/START key is activated. If the object is energized, measurement is disable as soon as it is contacted with the test probes. If the ON/START key is pressed first and the test object is contacted with the test probes afterwards, the fuse blows.
13 Special Functions – EXTRA Switch Position Setting Limit Values ∆U Select the EXTRA Switch Position Limit Value: EXTRA 13.1 ∆U % > Limit Value UL RL Voltage Drop Measurement (at ZLN) – Function ∆U Red Significance and Display of ∆U (per DIN VDE 100-600) Voltage drop from the intersection of the distribution network and the consumer system to the point of connection of an electrical power consumer (electrical outlet or device connector terminals) should not exceed 5% of nominal line voltage.
