Digital
,Digital multi-meter functions:(5)
- Correct Answer - High input impedance
Automatic ranging of measurements
Automatic polarity identification
Sample and hold circuitry
Provides a greater number of testing functions
Analog multi-meter functions:(3)
- Correct Answer - Low impedance
Fast meter reaction time(measurement time)
Provides a quick go or no-go indication
What is a device that measures the current flowing through a wire or
circuit?
- Correct Answer - Ammeter
Ammeters are also known as?(5)
- Correct Answer - Clamp-on ammeter
Amprobe
Clamp meter
Current probe
,Tong tester
Which test equipment works by reading the magnetic field around the
conductor?
Correct Answer - Ammeter
What is a unit that a signal technician uses to troubleshoot existing loops
and test newly installed loops?
- Correct Answer - Loop Analyzer
What does a loop analyzer measure?(5)
- Correct Answer - Frequency
Relative strength
Impedance
Change in inductance when vehicle is present
Resistance
Define TDR?
- Correct Answer - Time domain reflectometer
What is an electronic instrument used to characterize and locate faults in
metallic cables?
, - Correct Answer - TDR - time domain reflectometer
Because of the sensitivity to impedance variations, a TDR may be used
to: (3) - Correct Answer - Verify cable impedance characteristics
Splice and connector locations
Estimate cable lengths

intersection a chance to proceed through the intersection on a green
indication? - Correct Answer - Cycle
What is the total number of seconds between the start of a specific
display until that display comes up again called? - Correct Answer -
Cycle length
In older electro-mechanical controllers the cycle is sometimes referred to
as a? - Correct Answer - Dial
Describes the direction of approach and the maneuver made at the
intersection? - Correct Answer - (Vehicle) Movement
Vehicle movements are usually recorded in a "what" that is typically
included in the plans for a traffic signal? - Correct Answer - Timing chart
