ANALOG & DIGITAL DISPLAY

Most Ground Resistance Testers have an analog or digital display, or an LED indicator. Analog meters display values on a dial, typically with a needle that moves when a signal is applied. Digital meters provide a numeric reading. Light emitting diode (LED) and liquid crystal display (LCD) are common types of digital displays. LED indicators use a light to indicate that a test is occurring. In some models, the LED light blinks on and off throughout the test.

Ground Resistance Testers come with several different interfaces. Choices include GPIB, RS232, printer port, scanner port, and print out. General-purpose interface bus (GPIB) is designed to connect computers, peripherals, and laboratory equipment. RS232 interfaces for ground resistance testers are used for serial communications between instruments and computers. Printer port devices have a connector or port that is designed to interface with a printer. Scanner ports are similar to printer ports, but are designed to interface with a scanner. Another common interface for ground resistance testers is a print out. Print outs are hard copies of formatted data collected during testing. Other interface types for ground resistance testers are also available.

GROUND RESISTANCE TESTERS SPECIFICATIONS

• Widely applied in ground resistance measurement, loop resistance measurement in fields such as electric power, telecommunications, meteorology, oil field, architecture and industrial electrical equipment .

• When measuring ground system with loop, there is no need to disconnect the ground wire without auxiliary electrode, which means safer and faster.

• Clamp Earth Resistance Tester can measure the ground fault which can not be measured by traditional method, can apply in the occasion where traditional methods are unworkable.
