sed to remove batteries when not using the in- strument over a certain period of time. Howe- ver, should the instrument be contaminated by leaking battery cells, you are kindly requested to return it to the factory for cleaning and inspec- tion. Instruments must be stored in dry and closed areas. In the case of an instrument being transported in ex- treme temperatures, a recovery time of minimum 2 hours is required prior to instrument operation. 3.0 Safety Measures The UNITEST TELARIS LOOP has been designed and checked in accordance with the safety regulati- ons for Electronic Test and Measurement Instru- ments EN 61010 and IEC 1010, and left our factory in a safe and perfect condition. To maintain this con- dition the user must pay attention to the safety re- ferences contained in this instruction manual. The respective accident prevention regulations established by the professional associations re- garding electrical systems and equipment must be strictly met for all tasks. In order to avoid electrical shock, the valid sa- fety and VDE regulations regarding excessive contact voltages must receive the utmost atten- tion, when working with voltages exceeding 120V (60V) DC or 50V (25V)rms AC. The values in brackets are valid for limited ranges (eg for medicine and agriculture). If the operator’s safety can no longer be gua- ranteed, the instrument is to be put out of ser- vice and protected against use. The safety is no longer guaranteed, if the instrument: • shows obvious damage • does not carry out the desired measurement. • has been stored for too long under unfavou- rable conditions. • has been subjected to mechanical stress du- ring transport. The instrument may only be used within the operating ranges as specified in the technical data section. Avoid any heating up of the instrument by direct sunlight to ensure perfect functioning and long instrument life. The Earth Loop Resistance Measurement In- strument complies with the overvoltage class CAT III / 300V and may only be used for mains systems of maximum 230 V (fused at maximum 16 A). Only use the mains cable supplied. The unit was calibrated with this cable and only in this way can the resistance values measured be exactly indicated.

The loop impedance (L-PE / loop impedance) is un- derstood as the sum of all resistance values within a current loop, consisting of the resistors of the cur- rent source, the external conductor of the current source up to the measurement point and the return line (PE conductor) until the other current source pole. The measurement determines the loop impe- dance between external conductor and the PE con- ductor. The Loop impedance value is measured by short-term mains loading. Additionally, the instrument TELARIS Loop allows the user to test the mains internal resistance mea- surement (L-N). This measurement is not required by DIN VDE [German Standard], however it is con- sidered as important and valuable support in prac- tical applications e.g. for evaluating an installation as well as for trouble shooting. Simultaneously to measurement, the instrument TELARIS LOOP determines (by calculation) the short-circuit current. The short-circuit current must be known to guarantee that an excess current re- lease having been switched in series can trigger at an appropriate current level and thus at sufficient speed in the event of short-circuit. Terms: Loop Impedance (ZL): Sum of impedance values within a current loop (bet- ween the L and PE conductor). Internal Resistance (RI): Sum of resistance values within a current loop (bet- ween the L and N conductor). RL: Phase resistance RPE: Protective conductor resistance RN: Neutral conductor RE: Earth-Resistance Short-Circuit Current (IPSC): Occurring current flow in the event of short circuit. Specified Threshold Value of Contact Voltage (UL): Peak value of contact voltage (Limit), which may be maintained without time limit under specific envi- ronmental influence and corresponding to an rms value of 25V / 50V AC 6 General Information V ZL Voltage-Source

Prior to any measurement, test the instrument for perfect functioning by using a functional EUT. This could be a correctly wired socket of which perfect functioning is known. To obtain precise measurement results, switch off all loads or disconnect them from the mains. An exact measurement may only be carried out using the supplied test lead / mains lead. The in- strument has been calibrated with this cable. If other cables are employed, the measurement accuracy can no longer be guaranteed. If several measurements are carried out during a short period the temperature monitor is trig- gered. After a short cooling-down period, the measurements may be resumed. For resistance measurements in compliance with 6.1, 6.2 and 6.3, the ground conductor must not be live in order to comply with the respective specifications. 6.1 Loop Impedance Measurement / Short-Circuit Current Measurement � Connect the mains lead to the mains connector (13). � Select the measurement function R via the fun- ction switch (17). � Connect the test cables / mains plug to UUT / socket by respecting correct polarity � Set a voltage contact limit using the key (15) of the screen. The socket is continuously monitored for per- fect functioning. If the symbol (6) "Reverse mains plug” is displayed, the plug has to be tur- ned or the connection N and L of the three-pole test lead have to be reversed. If the symbol “Socket Error” (5) is displayed, an internal mains error exists. If the voltage between N and PE exceeds the selected (50V/25V), "UB>UL" (3) is displayed. For a complete socket test the contact elctro- de (16) must be touched, and the LC-display must be watched. If the symbol “socket error”(5) is displayed a PE error exists. � Press key “Start” (18) � Wait for approx. 5 seconds, during this the dis- play shows “-” � Read the measurement result on display. � By pressing the key “Display” (23) you may now select the different measurement values. If the RL conductor resistance exceeds 19.99 Ω, the measurement is interrupted and the message "Attention (1) + Limit (2) + RL" is dis- played. 8 Carrying out Measurements
