Earth/Ground Tester

Procedure of Measurements

2.Connect instrument according to picture.

3.In this mode, all settings and LIMIT values available can be called with "DISPLAY MENU" and the measuring frequency can be set.

4.Press "START TEST" button.

5.Read out measured value.

Resistance Measurement (RF)

In this measuring mode all resistances from 0.001 Ω to 3 kΩ can be measured with DC voltage and automatic polarity reversal as per EN61557-5.

To achieve highest accuracy 4 pole measurements are possible. To balance the extension lead, a compensation has to be done.
