300
On this meter, you might would need to analyze your thoughts as a spectator.
What is a Spectrum Analyzer
300
Ideally, an oscilloscope presentation should cover what vertical portion of the screen?
At least 60% of the vertical trace.
300
Name two methods to measure Current.
Multimeter, Oscillscope, Ammeter, and Current Tracers
300
What device is used to crank voltage to measure higher resistance?
Megger
300
Which is more accurate, the bridge or reactance-type meter?
Bridge
400
On this meter, you will need to count the amount of time it takes to complete a lap.
What is a Frequency Counter.
400
At what point on a meter movement are the most accurate readings taken?
Midscale
400
What is the primary advantage of using a current probe?
Current probes enable you to perform current measurements without disconnecting wires. Current probes are clamped around the insulated wire.
400
Why are digital multimeters well suited for testing sensitive devices?
The current flow through the component is limited to 1 milliamp.
400
What type of core produces the greatest inductance?
Magnetic-Metal Core
500
On this meter, you might be ask a friend to hold the reigns for a better effect then coffee.
What is a Megger
500
The input impedance of your test equipment should exceed the impedance of the circuit under test by what ratio?
10 to 1
500
When using an oscilloscope to calculate current, what law is used to find the unit of measurement?
Ohms Law
500
How do you compensate for the resistance of the test leads of a meter?
By zeroing the meter with the test leads shorted.
