4.2 Connecting Test Leads and Ground Pins

The ETCR3200C supports various connection methods depending on the test type. Refer to the diagrams on the inside lid of the case and the following general guidelines:

For Grounding Resistance (3-wire or 4-wire method): Connect the test leads to the corresponding terminals (E, P, C, H) on the meter. Insert the ground pins into the earth at appropriate distances as per the specific test method requirements.
For Soil Resistivity (4-pole method): Connect the four test leads to the C1, P1, P2, C2 terminals. Position the four ground pins (electrodes) in a straight line at equal distances for the Wenner method.
For Double Clamp Method: Connect the two current clamps to the designated clamp inputs on the meter.

5.1 Ground Resistance Testing

This method uses the rated current pole changing method. The measuring current is a maximum of 20mA.

Connect the test leads and ground pins according to the 3-wire or 4-wire method as shown in the diagrams.
Turn the rotary switch to the 'Grounding' position.
Press the TEST button to initiate the measurement.
The result will be displayed on the LCD screen.

5.2 Soil Resistivity Testing (Quadrupole Method)

This method utilizes the Wenner method for accurate soil resistivity measurements.

Connect the four test leads to the C1, P1, P2, C2 terminals and position the ground pins at equal distances.
Turn the rotary switch to the 'Soil Resistivity' position.
Set the electrode spacing range (1m to 100m) using the appropriate buttons if adjustable.
Press the TEST button.
The soil resistivity value will be displayed in Ωm.

5.3 AC Current Testing

The meter can measure AC current up to 600.0A using the provided current clamps.

Connect the current clamps to the meter.
Clamp the current clamps around the conductor carrying the AC current.
Turn the rotary switch to the 'AC Current' position.
The AC current value will be displayed.
