DUOYI Digital Ground Resistance Meter Tester, Model: DY4100B

1. Ground resistance Re (Rg when testing soil resistivity p)
2. Range: 2 ohms/20 ohms/200 ohms/2000 ohms (test range: 0.03~2.000 ohms/0.03~20.00 ohms/0.03~200.0 ohms/0.03~2000 ohms)
3. Soil resistivity: 2 ohms/20 ohms/200 ohms/2000 ohms (test range: 0.2~376.8 ohms.m/0.2~3768 ohms.m/0.2~37.68k ohms.m/0.2~376.8k ohms.m/)
4. Soil resistivity test: 4-pole method (only applicable to DY4100B)
5. Soil resistivity refers to the resistance of soil to current per unit length and unit cross-sectional area, and is a measure of the soils resistance to current intensity
6. Voltage to ground (AC voltage): 600V Test range 0~600Vac
7. Photovoltaic voltage (DC voltage): 1500V Test range: 0~1500Vac
8. Test method: voltage drop method (applicable to the current and voltage test of the probe)
9. Display: segment LCD display, display backlight
10. Battery voltage warning: battery logo display
11. Continuous test times: In the 2 ohm range, test once every 30 seconds with a 1 ohm load, and can be repeated more than 400 times
12. Input exceeds display: Display "OL"
13. Automatic shutdown function: If there is no operation for 5 minutes after the key operation, the system will enter the automatic shutdown state
14. Overload protection: AC280V/10 seconds between E-S ports
15. Withstand voltage: AC3540V (50/60Hz)/5 seconds between electrical circuit and outer box
16. Insulation resistance: 50 milliohms or more/DC 1000V between electrical circuit and outer box
17. Power supply: 6 AA batteries (not included)
18. When testing ground resistance and soil resistivity, the series interference voltage will be automatically tested synchronously, and a prompt will be given if there is an abnormal test result
