Which of the following precautions should be taken when troubleshooting various power circuits using a digital multimeter?

Question

Accepted Answer

When in the manual ranging mode, always preset the meter to the next higher range than the amount of voltage expected in the circuit.

Answer

Always remember that the unit is polarity sensitive and if used on DC circuits reversing the leads may result in high temperatures within the tester.

Answer

Never connect the device to circuits where potentials greater than 120 volts may be present, as the internal electronics can only withstand small currents.

Answer

Never use this type of meter on circuits greater than 60 Hz as the meter may not register voltages over 60 Hz.
