[. . . ] of measurements = 2 means that 2 earth measurements have been taken consecutively) secondary display on the right-hand side = average of the measurements taken ((Val1+Val2)/no. of measurements = (0. 90+0. 96)/2 = 0. 93) - 3rd measurement: main display = measured resistance value (Ex: 0. 93) secondary display on the left-hand side = 003 (no. of measurements = 3 means that 3 earth measurements have been taken consecutively) secondary display on the right-hand side = average of the measurements taken ((Val1+Val2)/no. of measurements = (0. 90+0. 96+0. 93)/3 = 0. 93) EN - 13 GP-2 GeoTest NOTE!A test with a result over 700 is not inserted in the calculation of average value. Example: 1st measurement Main display: 1, 07 Secondary display on the left-hand side: 1 Secondary display on the right-hand side: 1, 07 2nd measurement Main display: 4, 15 Secondary display on the left-hand side: 2 Secondary display on the right-hand side: 2, 61 3rd measurement (not inserted in the average value) Main display: 1018 Secondary display on the left-hand side: 2 Secondary display on the right-hand side: 2, 61 CLR Press CLR if you want to cancel the average resistance value and the no. of measurements, which are included in the calculation (displayed on the secondary displays on the right-hand side and on the left-hand side respectively). A screen similar to the following will be displayed: 0. 96 ----- Last resistance value measured NOTE! The resistance measurement is taken according to a 4-wire voltmetric method. 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. F If the amperometric circuit is interrupted, when pressing GO the instrument will not read the minimum current, therefore a screen similar to the one beside appears. Make sure that the terminals are connected correctly and that the amperometric rod (blue conductor) has not been driven into a gravelly or scarcely conductive ground. If necessary, pour water around the rod. rC indicates an high resistance value. ----- WARNING c SAVE THIS RESULT CANNOT BE SAVED. EN - 19 GP-2 GeoTest F In case both the amperometric circuit and the voltmetric circuit are interrupted, when pressing GO the instrument will not read the minimum current nor the minimum voltage, therefore a screen similar to the one beside appears. Make sure that the terminals are connected correctly and that the amperometric and voltmetric rods (blue and red conductors) have not been driven into a gravely or scarcely conductive ground. If necessary, pour water around the rod. WARNING --P c rC and rP indicate an high resistance value both for the voltmetric circuit and for the amperometric circuit. SAVE THIS RESULT CANNOT BE SAVED. WARNING F If the resistance measurement is higher than the full scale of the instrument, 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 ---- 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. 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. 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.

EARTH RESISTANCE MEASUREMENT PURPOSE OF THE TEST This test is carried out to make sure that the protective device is coordinated with the earth resistance value. 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. [. . . ]
