[. . . ] Therefore, it is not affected by the resistance value of the cable used: it is not necessary to calibrate the cables or their extension. SAVE The test results can be stored in memory by pressing SAVE (see paragraph 5. 1) EN - 14 GP-2 GeoTest 4. 3. "" MODE (Resistivity of the Earth) The measurement is taken according to CEI 64. 8, IEC 781, VDE 0413, EN61557-5 standards. 4. 3. 1. Selecting the units of measure WARNING Whenever the units of measure are changed the instrument will perform a hard reset and all the data in the memory will be erased (see paragraph 6. 1). SELECT THE UNIT press and hold the "RCL" key and turn the rotary switch. The instrument will display a screen that permits selection of the correct measurement unit: m or ft (used to determine distance between the ground rods) with the s or t keys. Press the SAVE or ESC key to save the measurement unit selected. NOTE! Regardless on the unit of distance D set up (either ft or m) the resistivity will be automatically calculated in OhmMeters! 4. 3. 2. Operating Instructions Measuring procedure: F F F Drive the 4 earth rods into the ground at the same distance D. The distance D between the rods is usually 3 to 30 ft (1 to 10 m). The distance D between the rods determines the depth at which the earth resistivity is measured. In order to identify the distance (and therefore depth) corresponding to the lowest resistivity value, the test must be repeated several times, positioning the rods at different distances. This depth will then have to be physically reached by the rods of the earth equipment. Insert the 4 connectors (black, red, blue and green) of the cables into the corresponding input terminals of the instrument (E, S, H, ES). >1999 ---- WARNING F If the resistivity measurement is higher than the quantity 1999x6. 28x(distance between the rods selected) when pressing GO the instrument performs the test and a screen similar to the one beside appears. 1999 is the full scale of the instrument. >1999 ----- EN - 20 GP-2 GeoTest F If the instrument measures an interfering voltage higher than 30V on the amperometric circuit, it does not perform the test and a screen similar to the one beside appears. UC indicates the presence of too high voltage on the amperometric circuit. WARNING --UC --- SAVE THIS RESULT CANNOT BE SAVED. F If the instrument measures an interfering voltage higher than 5V on the voltmetric circuit, it does not perform the test and a screen similar to the one beside appears. Interfering voltage measured. --230v - -230 WARNING SAVE THIS RESULT CANNOT BE SAVED. EN - 21 GP-2 GeoTest 5. HOW TO SAVE, RECALL AND CANCEL DATA 5. 1. TO SAVE: "SAVE" KEY If you want to save the test results: SAVE Press SAVE once. A screen similar to the one beside is displayed for 3 seconds, the instrument emits a sound, then the screen corresponding to the last measurement taken is displayed. No. of memory location where the measure has been saved. MEM 003 EN - 22 GP-2 GeoTest 5. 2. TO RECALL: "RCL" KEY If you want to review the test results: 1. RCL Press RCL. If the memory contains measurements, a screen similar to the one beside will be displayed. No. MEM 003 If the memory is empty, a screen similar to the one beside will be displayed. MEM Message "rEc ord": the memory contains no values, therefore it is impossible to recall them. EC C t 2. s Press t , s to select the number of the memory location you wish to consult. 3. DISP Press DISP to display the test result associated to the selected memory location. t 4. [. . . ] You cannot take off hand a limit earth resistance value as a reference for the test result: occasionally you must make sure that the prescribed coordination is respected. EQUIPMENT PARTS TO BE TESTED The earth equipment and its working conditions. The test must be carried out without disconnecting the earth references. ADMISSIBLE VALUES The earth resistance value, however measured, must meet the following requirement: RE < 50 / Ia where: RE= measured resistance of the earth equipment. [. . . ]
