| Question | Answer |
| _____ are tools that you can use to measure circuit quantities. | Meters |
| There are two basic types of meters used today: the _____ meter and the _____ meter. | analog, digital |
| An ____ meter contains a moving pointer and a calibrated scale. | analog |
| In an analog meter, the current that causes the pointer to move all the way to the right end of the scale is called _______. | full-scale current |
| Two types of analog meter are used in measuring current: the _____ and the _________. | ammeter, volt-ohm-milliammeter (VOM) |
| The abbreviation for "volt-ohm-milliammeter" is ____. | VOM |
| A ____ has multiple scales for measuring current, and can generally measure current in a range from microamperes up to about 10 A. | VOM |
| Digital meters are usually called ______. | digital multimeters (DMM) |
| The abbreviation for "digital multimeter" is ____. | DMM |
| A ______ gives readouts of current values on a four-digit display. This type of display gives more exact measurements than analog meters. | digital multimeter |
| A _____ is used to measure voltage. | voltmeter |
| High-voltage circuits should never be measured without the use of an accessory probe called a _______. | high-voltage probe |
| ______ is a feature on a digital meter where the range is automatically set inside the meter. | Autoranging |
| ______ is a feature on a digital meter where the meter displays the polarity of the voltage. | Autopolarity |
| An _____ contains an internal battery, a milliammeter, and a scaling resistor. | ohmmeter |
| Always observe two cautions when taking resistance measurements: First, be sure to remove all circuit power. Second, ________________ to the component. Parallel paths will greatly lower the ohmmeter's readings. | remove any parallel circuit paths |
| A _______ is the checking of a circuit to see if current flows (that it is in fact a complete circuit). | continuity test |
