Voltmeter Training

1. The bar graph on the display is most helpful when viewing:

• DC voltage readings only
• rapidly changing signals
• sine wave readings
• frequencies

2. The function buttons on the meter may be used to ___

• increase the rotary dial capabilities of the meter
• convert the meter from auto to manual ranging
• Both A and B
• None of the above

3. A student uses a multimeter to measure resistance of a wire and gets a reading of 7.4 k? What would this value be in ohms

• 0.74 ohms
• 74 ohms
• 740 ohms
• 7400 ohms
• 74,000,000 ohms

4. What position are test leads in ti check resistance?

• Red in volts, ohms Black in Amp
• Red in Amp & Black in Com.
• Red in Volt, Ohm & Cap Black in Com
• Either A or B

5.Of the following four diagnostic products which is the best suited for making exact voltage measurements when pinpoint testing an electronic circuit?

• Option 1Jumper wire with attachments
• Non-powered test light
• Fused jumper wires
• High-impedance digital multimeter

6. Safety is a concern when using test instruments. You can protect yourself by testing the meter for one of the following before conducting any tests.

• Test for good meter fuses
• Test the dial for movement
• Test for terminal connection
• Test for ground

7. Student A states using the Amperage setting on the multimeter you can measure the current flow in a circuit. Student B states that the Frequency setting is used to test for Ohms. Who is correct?

• Student A
• Student B
• Both Student A and Student B
• Neither Student A nor Student B

8. After testing the fuses it was determined that the 0.5 amp fuse was bad. Student A indicates they do NOT have an exact replacement fuse, but a cheaper replacement fuse of similar size is acceptable to use. Student B states the correct replacement fuse is specially designed to protect the user in case of an unexpected high amperage draw. Who is correct?

• Student A
• Student B
• Both Student A and Student B
• Neither Student A nor Student B

9. The function buttons on the meter may be used to _____________________.

• increase the rotary dial capabilities of the meter
• convert the meter from auto to manual ranging
• Both A and B
• None of the above

10. To capture a maximum value automatically during testing, which function button would you press?___________________.

• Hz/DUTY
• HOLD
• REC
• REL
