Fluke 1625-2 Earth ground meter

Earthing measuring devices, such as the Fluke 1625-2 are essential tools for troubleshooting. They contribute to maximize the system availability and reduce the risk of electric shock for the user. If fault currents do not have a properly designed and maintained earthing system a path to the earth, you unwanted paths to follow and can also the way by the human body.

There is not properly grounded, the likelihood of operating interferences. Without efficient earthing system can result in electrical devices to instrument errors, distortion factor - and power factor problems and a wide variety of sporadically occurring errors may occur. Studies show that 25% of the power supply quality problems are due to a lack of earth.

Stakeless measuring
With the earth ground tester Fluke 1623-2 can be earth resistances easily measured with current probes. In this measuring method, two clamps to the Depth earthing and connected to the measuring device. No Ground skewers. Using one of the pliers is a well-known fixed voltage induced, and with the second pliers, the current is measured. Then, the measuring instrument automatically switches the resistance of the low-operated tector. This measuring method can only be used if the building or structure to be measured to the measured a grounding system is connected. However, this is usually the case. If only one path to ground exists, as is the case in many residential areas, provides the spike-less procedure not acceptable value. In this case, the test must be carried out by means of the voltage drop procedure.

For spike-less procedures must not be disconnected the depth earthing, so that the connected earthing system during the test remains intact. The days of the enormous time required for placing and connecting of Skewers at any depth grounding in the system are finally a thing of the past. This saves a lot of time. You can ground measurements in buildings, on electrical towers and everywhere, where an access to the soil is not possible.

The measuring instrument with the largest range of functions
Fluke 1623-2 is a unique earthing measuring device, which all four types of earthing measurement can perform.
• 3- and 4-pin voltage drop method (with skewers)
• 4-pole earth resistance measurement (with skewers)
• Selective measurement (with a pair of pliers and skewers)
• Spike-free measurement (only with two clamps)
