What is the purpose of the Earth Resistance Test?

• To measure voltage levels

• To test the resistance of the earth electrode

• To calibrate electrical devices

• To check the current flow

What device is used for measuring earth resistance?

• Multimeter

• Earth Resistance Tester

• Clamp Meter

• Oscilloscope

How far should the voltage spike be placed from the earth electrode during testing?

• 20 meters

• 15 meters

• 10 meters

• 5 meters

What is the minimum number of tests recommended to avoid inaccurate readings?

• Four

• One

• Two

• Three

What should be checked before using the Earth Resistance Tester?

• User manual

• Battery level

• Calibration certificate

• All of the above

What is the formula to calculate the average resistance from three readings?

• Z = Z1 + Z2 + Z3

• Z = (Z1 + Z2 + Z3) / 3

• Z = Z1 * Z2 * Z3

• Z = (Z1 - Z2 - Z3) / 3

What color is the conductor used to connect to the earth electrode?

• Red

• Blue

• Green

• Yellow

Who should witness the earth resistance testing?

• Only the contractor

• Only the developer

• Site representatives

• No one is required

What action should be taken if a reading fails to meet the required standard?

• Stop the testing process

• Change the tester

• Add more rods

• Ignore the reading

What is the significance of the calibration certificate?

• It shows the tester is new

• It is only needed for legal purposes

• It indicates the tester is accurate and valid

• It is not important
