The PosiTest HHD C High voltage Holiday Detector is a
Continuous DC Holiday Detector designed to locate defects and
discontinuities (called "pinholes" or "holidays") in a coating system
applied to a conductive substrate. High voltage holiday detectors are
commonly used to inspect non-conductive coatings thicker than 500
µm (20 mils).
Designed for maximum utility, the powerful Li-on batteries of the
PosiTest HHD C fit neatly within the wand handle eliminating the
need for a separate battery box—reducing weight and eliminating
operator fatigue.
IMPORTANT:
fully understand this manual prior to using the PosiTest HHD C.
WARNING:
to 30,000V (30kV). Accidental contact with the electrode may result
in an electric shock. Always keep the working end of the electrode
away from your body and never touch it when activated. The
PosiTest HHD C operator should exercise care to minimize their risk
of electric shock and be aware of all relevant safety guidelines
before using this equipment.
The ribbed end of the instrument is designed to maximize the
distance between the electrode collar and the operator. The
electrode and ribbed end of the instrument should not be touched
when the PosiTest HHD C is in Detection Mode.
When in Detection Mode (pg. 4) generating high voltage or if an arc
is being produced, the PosiTest HHD C will generate broadband
Radio Frequency emissions. Care must be observed in the vicinity of
sensitive electronics or radio equipment.
