ITEMS DESCRIPTION
VICTOR 4108C Large Grounding Grid Grounding Resistance Tester
Notice:
The standard package don't include batteries.Because,the international air shipping forbid to ship liquid,powder and batteries,
we can not put them in the package box.Hope you can understand buy them in your local store or supermarket.
At the same time, please forgive us that we are unable to provide the English user manual.
If you need it, please contact the customer service after purchase.
Thanks for your support!
VICTOR 4108C digital large-scale grounding network grounding resistance tester, also known as power frequency grounding resistance tester, grounding resistance meter, etc., is a commonly used instrument for testing and measuring grounding resistance. It adopts a new variable frequency AC power supply, dual-frequency measurement technology, large touchable color screen and microprocessor technology to meet the impedance requirements of two-wire, three-wire, and four-wire testing. It can also measure soil resistivity, step voltage, distributed potential, and contact voltage. , Current phase angle and other parameters. It is suitable for telecommunications, electricity, meteorology, computer rooms, oil fields, power distribution lines, tower transmission lines, gas stations, factory grounding grids, lightning rods, etc., and meets the standards of electrical substations and lightning protection devices. The instrument test is accurate, fast, simple, stable and reliable. The maximum open circuit voltage of this tester can reach 400V, and the maximum short-circuit current can reach 5A. Microprocessor control and automatic dual-frequency technology can accurately measure and calculate the ground impedance value under the 50Hz power frequency state under strong interference conditions, and the large-screen display is clear at a glance. Store 100 sets of data at the same time, the resistance measurement range: 0.030Ω~2000Ω. The measurement data can be printed out by a thermal printer. VICTOR 4108C digital large-scale ground grid grounding resistance tester is composed of a host, a test wire, a ground rod, etc. It has the functions of reading, consulting, saving, and printing historical data.
