2.2 TYPICAL USES (ALWAYS USE A HOT STICK)
■ Identify and check live cables
Check and detect live high voltage cables
■
■ Find fault in flexible cables
Check grounding equipment
■
■ Service neon lighting
Trace live wires
■
■ Check high frequency radiation
■ Detect residual or induced voltages
WARNING: The 275HVD detects radiated electrical fields. To
accomplish this, an energized cable or sample must radiate an
electrical field. Shielded cables or shielded samples do not radiate,
or radiate very small electrical fields. Also, cables with concentric
neutrals will have a smaller/lower radiated field than plain insulated
cables.
The 275HVD may not detect, as expected, an electrical field on
shielded cables (buried cables are often shielded) or shielded
samples and the 275HVD has lower sensitivity on cables with
concentric neutrals.
It is not recommended to use the 275HVD on shielded cables
or shielded samples. Use extreme care on cables with
concentric neutrals (use a low setting).
