In order to measure resistance in a series circuit, you must connect the probes of the multimeter in _____ with (across) the component or device being measured.
To measure resistance in a parallel circuit, you must _____ the parallel connection and test each resistor.
When measuring current, you must break open the circuit and connect the meter's leads in _____ with the other circuit components.
Multimeters are also called _________.
An _____ multimeter has a pointer needle that must be read against a printed scale when making measurements.
Digital VOMs have widely replaced analog VOMs for these main reasons: digital meters are ___________, are _______, and have a ________.
A ____ is a device that's used to create a low resistance path through a circuit.
The _________ knob on an analog multimeter is actually a variable resistor that's used to adjust the meter's pointer.
One major cause of inaccurate readings with an analog VOM is called ________. This happens when you don't look straight at the meter's scale.
Another term for "parallax error" is "______ error".
Another common error made when using analog VOMs is ______. This occurs when measuring voltage. The meter's internal resistance is less than the circuit being measured. Because current follows the path of least resistance, the current may go through the internal meter circuit instead of the usual path. In turn you get an inaccurate reading on the meter.
Analog multimeters are rated in _____.
A meter used for serious electronic troubleshooting should have no less than _____ ohms per volt.
