    4) RULES FOR A SAFE OPERATION The symbol “ ” has three meanings in this manual. The user must look carefully for the symbol “ ” during operation: Danger - Identify conditions and actions that may result risk or even death. Warning - identify conditions and actions that may result risk or even death.

    ● Never exchange the battery or open the battery compartment when the device is humid. Use a softy cloth to dry the device to proced with the exchange. ● Assure that the device is off for battery exchange or open the battery content. CAUTION ● Make sure that the terminals of the probes are connected to appropriate terminals of the instrument before performing a measurement. ● Remove the batteries when stores the instrument for long periods.

    7) DEVICE CONFIGURATION A. Battery Level Select the function EARTH VOLTAGE ou EARTH RESISTANCE. If the battery indication is “ ” means low battery and it need to be exchange, otherwise, the device will not operate correctly. Battery Symbol Battery Voltage ≥ 8,2V 7,8V ~ 8,1V 7,4V ~ 7,7V 7,1V ~ 7,3V ≤ 7,0V B.

  • Page 9: Operation

    8) OPERATION Warning When the device is developing ground resistance tests, the highest voltage between E and C must be 50V AC. Do not touch the external part of the probes or the au- xiliary stakes, to avoid eletric shock danger. A.

    Note ● Check the ground humid where the auxiliary stakes will be placed. If the groud is to dry, moist it a little. Rocky and sandy soils alson need to be moisted before testing. ● If the test site is in an urban center covered in concrete and difficult access to the stakes, use two steel plates 25cmx25cm(or the stakes pre-existing), place them ho- rizontally over the concrete surface then cover it with a moist cloth. Replace the measure earth in this situation, because in general cases it still can be used. B. Earth Voltage Measure WARNING The earth voltage test only works in V and E. The C and P cables must be separated, otherwise, the device is in risk of being damaged and the user suffer injuries.

    large, a shift in the range can be done. D. Simple Measure Danger To avoy eletrical shock risks, be careful when using a grounding point of commercial electric power systems as a point of reference test. This method can be used when there is not possible to use the auxiliary stakes.

    E. Special Functions ● Auto Shutdown The device will turns on when the buton is pressed and some function is selected. The auto shutdown happens after 10 minutes to save battery (except when the device is realizing ground resistance tests). ● Backlight When performing the tests in poorly lit areas, you can use the backlight of the display.

    Press “LIGHT/LOAD” again then the display will show the saved data number 02 e so on until the 20th saved data. If you want to return to previous data, press “HOLD/SAVE” once (in this case, “HOLD/SAVE” and “LIGHT/LOAD” are working as “up” and “down”). To disable the function, press “LIGHT/LOAD” for two seconds. 3. Erase the saved data: press the buttons “HOLD/SAVE” and “LIGHT/LOAD” simultaneously then turn on the device. The display will show “C L.” and all the data will be erased. 9) Specification A. General Specification ● Display: LCD 3 3/4 digits, 4000 counts ● Functions: Earth voltage measure and earth resistance measure.
