Description:1. Meet a variety of different occasions. Make measurements smarter and more convenient2.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.Specification:Mode: DY4100Resolution: 0.01Data Hold : yesWorking LED Indicator: yesFunction Symbol Display: yesTow Battery Warning: yesEarth Voltage: 0-30V (3%+5)Earth Ground Resistance: 0/20/200/2000 (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 4.b. safe working ground, the grounding resistance should not be greater than 4.c. the grounding resistance of the lightning protection ground should not exceed 100.d. For jointed grounding of shielded systems, the grounding resistance should not be reater than 10.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 thi
Description:1. When your car is parked for too long, the battery is depleted, or you forget to turn off the lights, the car cant start, it wastes a lot of precious time, and it also brings a lot of trouble. I believe many car owners have had such experience. . The emergency power supply should be recharged frequently. It must be carried with the car. Once it is forgotten to be charged or forgotten to carry, it still cannot solve the problem of no power start.2. In order to make it easier and more convenient, and to solve this problem completely, we have developed this car worry-free start treasure. This product is small in size and easy to install. As long as it is installed on the car battery, you dont have to worry about it. The car can be monitored and controlled automatically by the car without worry. When the battery loses power to a certain extent, it will limit the battery and save it. Even in the case of weak power, this worry-free starter can still start your car normally.Feature:Small size, low cost, easy to installDoes not affect the battery and the car, no need to break the lineDont worry about the battery losing power or forgetting to turn off the lights, so the car cant start.Suitable:Applicable models: all 12V carsBattery model: universal all 12V batteryApplicable voltage: 12VPackage weight: 563gPacking size: 13*13*5cmPackage Included:1 X Car Worry Free Charging Treasure1 X Positive Plate (or negative plate, optional, depending on the space next to the battery)
