Kyoritsu 4102A Earth Tester Key Features :

Ground Resistance Measurement:

• The primary function of the Kyoritsu 4102A is to measure ground resistance in electrical systems. This is essential for ensuring the effectiveness of grounding installations and preventing electrical hazards.

3-Terminal Earth Resistance Measurement:

• The tester typically employs a three-terminal measurement method for assessing earth resistance. This method provides accurate results by considering the resistance between the earth electrode, auxiliary electrode, and current-carrying electrode.

4-Terminal Soil Resistivity Measurement:

• Some models may include a four-terminal method for measuring soil resistivity. This allows users to evaluate the resistivity of the soil in which the grounding system is installed.

Digital Display:

• Equipped with a digital display, the tester provides clear and precise readings of ground resistance values. The digital format enhances visibility and facilitates quick assessments.

Auto-Ranging:

• The auto-ranging feature allows the tester to automatically select the appropriate measurement range based on the ground resistance being tested. This simplifies the testing process and ensures accurate results.

Data Hold Function:

• The data hold function allows users to freeze and retain the displayed measurement value. This is useful when recording measurements or working in locations where immediate reading retrieval may be challenging.

Alarm Function:

• Some models may include an alarm function that alerts users when the measured ground resistance exceeds a predetermined threshold. This feature enhances the ability to quickly identify potential safety risks.
