Select all that are true Question 6 options: The 4 wire ohms function is similar to the 2 wire function, but it offers additional protection against hazardous voltages. The 4 wire ohms function is more accurate, but generally only worth the trouble when resistances are small. The 4 wire ohms function allows you to keep the circuit powered up; you must remove power for the 2 wire ohms function. The 4 wire ohms function is more accurate, but generally only worth the trouble when resistances are high
