A

Front focused

25
Q

What area of the hot stick indicates the sensing section of the tool?

A

Red striped area

26
Q

The distance from a potential source at which the tool will begin to alert depends on what factors?

A

36
Q

In the low setting, the what of the beeping will increase as you move closer to the potential source?

A

Rate and intensity

37
Q

What setting is used to pinpoint a source and will only sound when pointed directly at the energized source?

41
Q

What can prevent the hotstick from immediately detecting voltage?

A

Shielding of any wire inside a grounded conduit

42
Q

Shielding of voltage is also possible from what?

A

Large wet trees and other natural objects with enough mass
