Final answer:
When measuring the output signal of a general motor vehicle with a digital multimeter, select the appropriate range for voltage or current measurement.
Step-by-step explanation:
When measuring the output signal of a general motor vehicle with a digital multimeter, the setting will depend on whether you are measuring the voltage (in volts) or the current (in amps).
Voltmeter Setting:
When measuring voltage, the digital multimeter should be set to a range that can read the voltage of the motor vehicle. You should use the voltmeter with a full-scale reading that is suitable for the expected voltage. For example, if the maximum voltage you expect to measure is 12 volts, you can use a digital multimeter with a full-scale reading of 0.300 volts.
Ammeter Setting:
When measuring current, the digital multimeter should be set to a range that can read the current flowing through the motor vehicle. You should use the ammeter with a full-scale reading that is suitable for the expected current. For example, if the maximum current you expect to measure is 5 amps, you can use a digital multimeter with a full-scale reading of 20.0 amps.
