Geotest <strong>2016</strong> Version EN 1.01 of 19/10/2000 τ σ Press σ and τ to select the value of the parameter D: 006 mρ Value of the parameter D ESC Press ESC to confirm the value previously set. GO Press GO to take the measurement and read the value on the display. At the end of the test a screen similar to the one following will be displayed. 36.5 Ωm ρ Measured earth resistivity value ν WARNING: When the message “Measuring” appears on the display, the instrument is measuring. Do not disconnect the crocodiles during the measurement. NOTE! If you keep pressing GO, the instrument takes more measurements consecutively. When a new value is acquired, the symbol Ω blinks on the main display, the instrument emits a short sound and, if the measured value is inserted in the calculation of the medium resistivity value, the message “Add” appears on the secondary display on the right-hand side.

Geotest <strong>2016</strong> Version EN 1.01 of 19/10/2000 The earth resistivity value is an indispensable parameter to calculate the resistance value of the rods which will be used for the earth equipment (see paragraph 11.2). AVG Use AVG to display the medium resistivity value measured. This key is enabled only when the message “Add” appears on the secondary display on the lefthand side. NOTE! The value of the resistivity corresponding to a resistance value over 700Ω is not inserted in the calculation of medium value. Example: 1 st measurement Main display: 6.6Ωm Secondary display on the right-hand side: empty 2 st measurement Main display: 26.Ω Secondary display on the right-hand side: Add Press AVG: main display: 16.4Ωm secondary display on the left-hand side: 2 secondary display on the right-hand side: Add 3 st measurement (not inserted in the medium value) Main display: 6.39kΩm Secondary display on the right-hand side: Add Press AVG: main display: 16.4Ωm secondary display on the left-hand side: 2 secondary display on the right-hand side: Add ESC Use ESC to leave the screen showing the medium value and return back to the screen corresponding to the last measurement taken. SAVE Press SAVE twice to memorise the test results (see paragraph 5.1). Example: You position the rods at a distance D of 1 meter and take 3 resistivity measurements: 7.7 Ωm ρ 7.1 Ωm 7.1 Ωm ρ ρ Add Add 1 st meas. 2 nd meas. 3 rd meas a) 1 st measurement: you see the measured value but not the message “Add”.
