Q

What setting narrows the receiving area to the front focal area allowing to pinpoint the source?

Study These Flashcards
A

Front focused

25
What area of the hot stick indicates the sensing section of the tool?
Red striped area
26
The distance from a potential source at which the tool will begin to alert depends on what factors?
Mode setting, magnitude of AC voltage, distance from source, shielding of potential sources, size of the area where the AC voltage appears to be coming from
27
What is the most common electrical problem the department responds to?
“Wires down”
28
Apparatus position and responding personnel are to maintain at least how many spans from affected wire or pole?
1 span (distance between poles)
29
If a pole is damaged, the distance between what will provide a best margin of safety (do not count damaged pole)?
2 undamaged poles
30
Turn the operating switch to the high setting and listen for a series of rapid beeps and LED flash lasting approximately how many seconds indicating the hot stick is ready for use?
3 seconds
31
The hot stick requires no warm up and is ready for use in how many seconds after turning it on?
5 seconds
32
What setting is utilized when looking for AC voltage in the general area?
High
33
In the high setting, of high voltage detected in the area, the device will begin beeping at what distances from the source and at a faster rate?
Greater distances
34
What setting can be utilized when working around other high voltage sources such as high voltage overhead power lines?
Low
35
What setting will help identify energized wires on or closer to the ground without alerting members to overhead power lines?
Low setting
36
In the low setting, the what of the beeping will increase as you move closer to the potential source?
Rate and intensity
37
What setting is used to pinpoint a source and will only sound when pointed directly at the energized source?
Front focused
38
When responding to TAs with potential electrical hazards, what setting should be used to alert the presence of a hazard from a distance?
High
39
As you move closer to a vehicle what setting on the hot stick should be used to better identify the presence of electricity?
Low
40
If no detection of the presence of electricity from a distance, continue to use the LOW setting in what direction of the vehicle?
Above, below and around all sides
41
What can prevent the hotstick from immediately detecting voltage?
Shielding of any wire inside a grounded conduit
42
Shielding of voltage is also possible from what?
Large wet trees and other natural objects with enough mass
43
Dragging your feet across the ground with cause what which is caused by friction and is not a true reading of AC voltage but could cause the hot stick to alarm?
Electrostatic voltage
44
Consider all electrical wires what until determined otherwise by DWP?
“Live” or “hot”
45
What works to restore power during power outages which is not way to predict when this will occur?
Automated machinery
46
Accidental regeneration of electricity may occur due to what on a downed wire into another energized source?
Wind blowing
47
What by portable generators can cause in-energized or “dead” wires to become energized without warning?
Back feeding
48
How often should the hot stick be inspected for any damage to the plastic housing?
After use and monthly
49
The hot stick can be cleaned by wiping it down with what?
Damp cloth
50
Do not use what and avoid spraying any fluids directly into beeper?
Abrasive or corrosive fluids
51
It is recommended to not allow what type of water to come in contact with the unit?
Salt water
52
The hot stick has been tested to operate continuously for how many hours by the manufacturer?
300 hours
53
How often should the 4 AA batteries be changed?
Annually or when discharged
54
If the batteries are low, the tool will emit what beeping sound a what LED light when turned on?
Solid beeping and LED light
55
To change the batteries unscrew what and once removed the end cap can be pulled out and batteries changed?
The lanyard
56
The direction and orientation of the batteries is also printed on what for proper installation?
Circuit board
57
Immediately after installing new batteries, turn on the hot stick and ensure that the device goes through a what?
Self check
58
If how many batteries are installed incorrectly, the device will sound continuously and the LED light will illuminate as well?
1 battery
