ALWAYS ensure that the ground lead is plugged into the PosiTest
HHD Verifier and that the other end of the ground lead is connected to the ground
lead of the high voltage holiday detector that is being verified. Failure to ensure
proper grounding may result in electrical shock.
WAR I G:
DO OT touch the TIP of the probe or the RED High Voltage Shield
with bare hands while the probe is in contact with a high voltage source. Electrical
shock could occur if operator touches the tip or shield with bare hands while in use.
WAR I G:
DO OT use this equipment in damp, wet or rainy conditions.

Step 1. Before using the PosiTest HHD Verifier, ensure that a proper ground is
established between the holiday detector and the verifier. Ensure that the ground
lead is plugged into the PosiTest HHD Verifier and that the other end of the ground
lead is connected to the ground lead of the high voltage holiday detector that is
being verified.
Step 2. Turn the PosiTest HHD Verifier on by pressing and releasing the power
button . Once powered on, the verifier continuously monitors the voltage on the
probe end of the verifier. The verifier will update the display when the probe is
touching an exposed electrode of a holiday detector. The voltage displayed on the
verifier should match the voltage displayed by the detector within the combined
tolerance of both units.

IMPORTA T:
An icon on the PosiTest HHD Verifier display will indicate if the detected
voltage is Pulsed DC [PDC] or DC [DC].
OTE:
uFor Pulse DC holiday detectors such as the PosiTest HHD, the verifier probe
tip can be left connected to an exposed electrode indefinitely with no concern.
For best results, try to position the verifier probe perpendicular (90°)
to the electrode on the holiday detector.
uFor Continuous DC holiday detectors, the verifier probe tip should just be
briefly tapped against an exposed electrode to obtain a measurement. The
Verifier will not update the display if left in contact with a continuous DC power
source. The PosiTest HHD Verifier display will not update properly if the
DC power source is adjusted while connected to the PosiTest HHD Verifier.
Prolonged contact with a continuous DC holiday detector may result in
overheating of the PosiTest HHD Verifier probe.
The PosiTest HHD Verifier is accurate to +/- 5% of the peak voltage presented to
the tip of the probe.
The PosiTest HHD Verifier is shipped with a Certificate of Calibration showing
traceability to a national standard. DeFelsko recommends customers establish
calibration intervals based upon their own experience and work environment. A
detector used frequently, roughly, or in harsh operating conditions may require a
shorter certification interval than a gage used less frequently and handled with care.
Based on our product knowledge, data and customer feedback, a one year
certification interval from either the date of calibration, date of purchase, or date of
receipt is a typical starting point.

PROBLEM: The PosiTest HHD Verifier is displaying a voltage different than
observed on the holiday detector
The PosiTest HHD Verifier is a Peak reading volt meter that can be used for both
Pulse DC and DC applications.
When used with Pulse DC type holiday detectors, it is important to maximize the
distance of the verifier tip to ground. This will reduce capacitive coupling to ground
of the high frequency DC pulse.
When used with a Continuous DC type holiday detector, the PosiTest HHD Verifier
will present a load to the holiday detector being tested and lowering of the output
voltage is likely. In such cases, repeated or slow contact with the electrode may
result in lower voltages being displayed on the PosiTest HHD Verifier. Operation
on some DC holiday detectors may yield higher than expected results due to
specific detector design.

DO OT use this equipment with high voltage power sources other
than high voltage holiday detectors. The PosiTest HHD Verifier has been
specifically designed to work with high voltage holiday detectors that have limited
power output. Since the maximum power dissipation of the PosiTest HHD Verifier
is 12.5 watts, connection to high power, high voltage sources such as mains supply
WILL overheat and damage the PosiTest HHD Verifier. DO OT connect the
PosiTest HHD Verifier to an AC power outlet.
