What is as important as performing the maintenance itself?
- Correct Answer - documentation of emergency maintenance.
When should documentation of a failure begin?
- Correct Answer - when a failure is traffic signal is first reported.
a Circuit that is wired in series is one where:
- Correct Answer - the current goes through all of the electrical
components of the circuit
a Circuit that is wired in Parallel is one where:
- Correct Answer - each component has its own direct path.
Circuits are wired in__________ and ___________
- Correct Answer - series and parallel
,Ohm's law is a set of formulas that describe the mathematical
relationship between:
- Correct Answer - Voltage (E), current (I), and resistance (R).
What is a load switch tester also known as?
- Correct Answer - Multi-switch tester
A Load switch tester or multi-switch tester is used to:
- Correct Answer - verify the correct operation of a load switch. The unit
verified that the correct current outputs are within the acceptable range
for operation.
Slot testers are available that:
- Correct Answer - plug into the cabinet detector card rack and enable
the technician to measure voltage, continuity and or resistance for each
internal connection in the cabinet.
A loop analyzer is a unit that:
- Correct Answer - a signal technician uses to troubleshoot existing
loops and test newly installed loops
An ammeter or current probe is:
, - Correct Answer - a device that measures the current flowing through a
wire or circuit.
A multimeter can detect the:
- Correct Answer - resistance, voltage, or current of an electrical circuit.
In the case of significant underground utility congestion or of the
presence of utilities with potentially catastrophic consequences if
damaged, a ______________ is a good option.
- Correct Answer - soft-dig
The following are some of the items that need to be considered when
determining the signal type:
- Correct Answer - What type of signal supports will be used, will
pedestrian features be required, are there any unusual roadway
geometric features that will need to be accommodated?
the typical tests for traffic signal conductors are:
- Correct Answer - functional such as the connection to the proper signal
display, induced voltage, and continuity
The cabinet should be oriented such the door opens away from the
intersection, and in a position that gives the field technician the:
- Correct Answer - greatest possible view
