AEMC 275HVD - Typical Uses (always use a Hot Stick)

6 Non-Contact, High Voltage Detector 275HVD
The 275HVD is battery powered and contains three standard 1.5V “C”
cells in the shaft below the sensing head.
Whenanelectricaleldisdetected,asoundannunciator(high-pitch,high
-powered buzzer) and visual indicators (bright LEDs) are triggered ON,
warning the user.
The body is made out of industrial grade UL rated polyamide (Type 66
Nylon).Theshotgunadapterattheshaftendisdesignedtotintomost
Hot Stick adaptors.
2.2 Typical Uses (always use a Hot Stick)
• Identifyandchecklivecables
• Checkanddetectlivehighvoltagecables
• Findfaultinexiblecables
• Checkgroundingequipment
• Serviceneonlighting
• Tracelivewires
• Checkhighfrequencyradiation
• Detectresidualorinducedvoltages
IMPORTANT WARNING
The275HVDdetectsradiatedelectricalelds.Toaccomplishthis,
an energized cable or sample must radiate an electrical eld.
Shielded cables or shielded samples do not radiate, or radiate very
smallelectricalelds.Also,cableswithconcentricneutralswillhave
asmaller/lowerradiatedeldthanplaininsulatedcables.
The 275HVD may not detect, as expected, an electrical eld 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).
