                  1. Meet a variety of different occasions. Make measurements smarter and more convenient
                  2.Measure the grounding resistance for about 5 seconds .Measure the grounding voltage for about 2 seconds.
                  3.The outer casing is made of thick material Resistance to falling,dust, moisture, etc. Have a protective effect for the instrument.

                  Mode: DY4100

                  Resolution: 0.01Ω
                  Data Hold : yes
                  Working LED Indicator: yes
                  Function Symbol Display: yes
                  Tow Battery Warning: yes
                  Earth Voltage: 0-30V ±(3%+5)
                  Earth Ground Resistance: 0/20/200/2000Ω± (2%+ 3)

                  Voltage range: can withstand 300V AC (1 minute)
                  Resistance range: can withstand 200V AC (10 seconds)

                  Grounding Resistance Test Requirements:
                  a. AC working ground, the grounding resistance should not exceed 4Ω.
                  b. safe working ground, the grounding resistance should not be greater than 4Ω.
                  c. the grounding resistance of the lightning protection ground should not exceed 100Ω.
                  d. For jointed grounding of shielded systems, the grounding resistance should not be reater than 10Ω.
                  e. DC working grounding, grounding resistance should be determined according to the specific requirements of the computer system.

                  Ground Voltage Measurement:
                  Please turn the dial switch to the grounding voltage "EV" file and connect the test line according to the grounding voltage test chart.
                  The ground voltage will be automatically displayed. Please make sure that the ground voltage is ≤10V. If the local voltage is >10V.
                  the grounding resistance measurement value may cause an error. At this point, the relevant electrical equipment can be powered off
                  to reduce the grounding voltage before measuring.

                  Earth Resistance Measurement:
                   Accurate measurement (with the equipped test leads) to puncture the P and C grounding pins to the depth of the ground.
                  They are arranged in a straight line with the grounding equipment and are spaced 5 to 10 meters apart.
                  (Note: Make sure the grounding pins are inserted in the wet soil. If the soil of the grounding nail is dry, it is necessary to add water or stone or the sand to be wet and test)

                  Package Included:
                  1 X DY4100 Ground Resistance Tester
