1The analog volt-ohm-milliammeter (VOM) is the most common measuring instrument used by technicians.
A)True
B)False



2DMMs cannot measure capacitors, diodes, and transistors.
A)True
B)False



3An analog multimeter uses a moving pointer and a printed scale.
A)True
B)False



4A moving-coil meter movement is generally used in an analog multimeter.
A)True
B)False



5The moving-coil arrangement is often called a D'Arsonval movement, after its inventor.
A)True
B)False



6Looking at a meter from the side increase the possibility of getting what is known as a parallax error.
A)True
B)False



7When the insertion of a current meter decreases the circuit current above that which exists without the meter present, the effect is called current meter loading.
A)True
B)False



8Most general-purpose analog VOMs have an accuracy of ±2%.
A)True
B)False



9A voltmeter has low resistance and is generally connected in series.
A)True
B)False



10When the measured voltage decreases because of the additional load current for the meter, the meter is said to be down.



11Voltmeter loading can be appreciable in circuits.



12A digital multimeter usually has an input resistance of about Ω.



13The ohm scale increases from right to left and is called a scale.



14A feature of most DMMs that selects the proper range for the meter and indicates the range as a readout is called .



15A circuit that converts analog voltage values to an equivalent binary form is called the converter circuit.



16Looking at a(n) meter from the side results in an optical error called parallax.



17 loading can be appreciable in high-resistant circuits.



18The loading effect is minimized by using
A)a voltmeter with very high resistance
B)a voltmeter with a very low resistance
C)a voltmeter with zero resistance
D)an ammeter with a very high resistance



19When the ohmmeter leads are open, not touching each other, the ohmmeter
A)is broken
B)is being zeroed
C)indicates no resistance
D)indicates infinitely high resistance



20When the zero adjust on an ohmmeter cannot deflect the pointer all the way to zero, it generally means
A)the potentiometer is faulty
B)the ohmmeter is shot
C)the fuse is blown
D)the battery voltage is too low



21An accessory probe that can be used with a multimeter to measure dc voltages up to 30 kV is called a(n)
A)scope probe
B)high-voltage probe
C)amplifier probe

C)1.2 V for silicon and 0.6 V for germanium
D)1.7 V for silicon and 1.3 V for germanium



23What is the term for a DMM that specifies how many places can be used to display the digits 0 to 9, regardless of the decimal point?
A)protocol
B)accuracy
C)revolution
D)resolution



24When measuring a fuse with an ohmmeter, a good fuse measures
A)0 Ω
B)∞ Ω
C)75 Ω
D)300 Ω
