_____ are tools that you can use to measure circuit quantities.
There are two basic types of meters used today: the _____ meter and the _____ meter.
An ____ meter contains a moving pointer and a calibrated scale.
In an analog meter, the current that causes the pointer to move all the way to the right end of the scale is called _______.
Two types of analog meter are used in measuring current: the _____ and the _________.
The abbreviation for "volt-ohm-milliammeter" is ____.
A ____ has multiple scales for measuring current, and can generally measure current in a range from microamperes up to about 10 A.
Digital meters are usually called ______.
The abbreviation for "digital multimeter" is ____.
A ______ gives readouts of current values on a four-digit display. This type of display gives more exact measurements than analog meters.
A _____ is used to measure voltage.
High-voltage circuits should never be measured without the use of an accessory probe called a _______.
______ is a feature on a digital meter where the range is automatically set inside the meter.
______ is a feature on a digital meter where the meter displays the polarity of the voltage.
An _____ contains an internal battery, a milliammeter, and a scaling resistor.
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.
A _______ is the checking of a circuit to see if current flows (that it is in fact a complete circuit).
