| Which of the following precautions should be taken when troubleshooting various power circuits using a digital multimeter? |
| A) Never use this type of meter on circuits greater than 60 Hz as the meter may not register voltages over 60 Hz. |
| B) 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. |
| C) Never connect the device to circuits where potentials greater than 120 volts may be present, as the internal electronics can only withstand small currents. . |
| D) When in the manual ranging mode, always pre-set the meter to the next higher range than the amount of voltage expected in the circuit. |
