Exam 9: Analog and Digital Multimeters

A higher ohms-per-volt rating means higher voltmeter resistance.

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

When testing a semiconductor diode with a DMM, normal values are

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

The current meter's resistance should be no greater than 1/100 of the circuit resistance.

Most analog multimeters have an ac voltage scale calibrated in

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

A moving-coil meter movement is generally used in a digital multimeter.

Most general-purpose analog VOMs have an accuracy of ±20%.

When the moving pointer of a VOM hits the right-pointer stop, the meter is said to be pegged.

Most general-purpose analog VOMs have an accuracy of about plus or minus (number only) ______________ percent.

What is the function of a DMM that automatically shifts it to a higher range as soon as an overload is indicated?

A D'Arsonval movement is generally used in a(n) ______________ VOM.

When the zero adjust on an ohmmeter cannot deflect the pointer all the way to zero, it generally means

When an ohmmeter is connected to a circuit in which power is on, the ohmmeter

A voltmeter has low resistance and is generally connected in series.

Some DMMs can measure capacitors, diodes, and transistors.

A wire conductor that is continuous without a break has practically ______________ ohms of resistance.

Looking at a meter while directly in front of it is known as parallax.

Any coil for a transformer, solenoid, or motor will have ______________ resistance if the winding is open.
