HIGH VOLTAGE HOLIDAY DETECTOR

(STICK UNIT)

HOLIDAY DETECTOR FUNCTION

1.

The Tinker & Rasor Model APS Holiday Detector is an all-purpose electrical inspection
instrument which maintains a given inspection voltage in spite of the electrical load on the
circuit. It is recommended for use on any pipe diameter as well as on flat surfaces when such
surfaces are coated with a highly electrical resistance material, and when the surface beneath
the coating is electrically conductive. The detector works equally well on damp or dry surfaces,
and is especially desirable where humid conditions prevail.

at additional cost.

NOTE: Additional accessories may ship in separate packaging.

Safety Information for User

Unpacking and Reviewing your Tinker & Rasor Holiday Detector Before Every Use

• Make certain the inside of the case is clear and dry.

• Inspect each component for damage, such as cables, instrument & wand handles.

• Make sure all of the electrodes are clean.

• Verify the unit is fully charged.

• Verify that the output voltage is correctly set to the coating manufacturers recommend

inspection voltage.

• If manufacturers requirements are not stated, NACE International, SSPC or ASTM Standards can
be followed.

AND……… ALWAYS READ THE INSTRUCTIONS THOROUGHLY PRIOR TO USING ANY TEST
EQUIPMENT!

WARNING! This is a HIGH VOLTAGE device capable of producing an electrical shock if not
properly grounded and/ or operated in accordance with the instructions and procedures
prescribed in this manual!

DANGER! IF YOU HAVE A PACEMAKER DO NOT USE THIS DEVICE.
If you have a pacemaker, life critical electronic medical devices or any medical condition effected by High
Voltage, DO NOT use this type of equipment. Only trained and responsible personnel should operate high
voltage equipment. Alert all personnel nearby prior to testing and display warning signs. It is important to
realize you are now using a high voltage, low energy holiday detector. Tinker & Rasor holiday detectors,
APS & AP/W, are designed to generate between 800 to 35,000 volts, pulsating DC. While these voltages
are high, the energy emitted is well within US, OSHA guidelines. https://www.osap.org/page/GuideOSHA
Rubber or plastic gloves and non-conductive footwear can minimize potential shock. Keep in mind that
the shock prevention effectiveness of the rubber or plastic glove and footwear is limited to the condition
of their protective surface. Make sure your gloves and footwear are in good condition and have no holes
or tears. Most Portable Holiday Detectors are limited to finding defects in nonconductive coating
materials. Testing should ONLY be conducted clear of personnel not involved in the testing procedure.
Personnel operating Holiday Detectors should always be aware of their environment and the safety
limitations imposed by same. Operator should have an alert assistant, to ensure that all unauthorized
personnel are kept clear of the testing area.
DANGER!!! Portable Holiday Detectors create an arc or spark. Use of a Portable Holiday Detector in or
around combustible or flammable environments can result in an explosion. When operating in any
potentially hazardous area, consult with the plant or site safety officer before proceeding with a holiday
detection test in any potentially hazardous or suspect area.
CAUTION! DO NOT USE AROUND SENSITIVE ELECTRONICS OR RADIO EQUIPMENT. When
“on” but not in use, Tinker & Rasor Pulse Type Holiday Detectors, APW and APS will generate radio
frequency emissions which are within the limit defined by the Electromagnetic Compatibility Directive.
Due to its method of operation however, the APW and APS Pulse Type Holiday Detector will generate

broadband RF emissions when the unit is generating high voltage or when a spark is produced at the
electrode. It is therefore recommended that the user does not activate the high voltage within the vicinity
of sensitive electronics or radio equipment.

DO NOT SHORTEN THE GROUND CABLE. NEVER TOUCH THE BARE GROUND WIRE WHEN THE
DETECTOR IS TURNED ON.

WARNING! USE CAUTION WHEN RAINING. If it is raining then there is a safety concern for the operator.
Surface water on the sub straight is usually not conductive enough to transmit voltage, but almost any
contaminant will cause water to become more conductive. If water covers the wand handle while
connected to the APW Power-Pak or the APS Instrument, then the operator could become the return path
for the high voltage. While the output voltage will cause harm to a healthy person, according to OSHA,
your environment must be taken into consideration when operating this type of equipment. For example;
if you are standing on top of a flag pole and receive a jolt of high voltage, it will most likely cause you to
jump, and you will fall off the flag pole.
If it isn’t raining, but the coating surface is wet, Tinker & Rasor Holiday Detectors are designed to
minimize the effects of damp or wet coatings. In extreme cases, “ghost” holidays might be witnessed,
should a continual path of water reach a holiday. If this continues, dry the sub straight and continue
testing.

It is important to note that all accidents are preventable. Take caution when using Tinker &

Rasor holiday detectors or any other high voltage test equipment.

Stay Alert, Stay Aware and Stay Alive

3. CHECK-OUT INSTRUCTIONS

• Remove all accessories from the shipping carton.

• Connect high voltage wand handle to front of instrument and ground cable to

detector handle (insert and twist clockwise). Never connect or disconnect the cable
or wand when the instrument is turned on.

• Attach electrode to the high voltage wand handle assembly and apply to the
structure to be inspected. The electrode should always make intimate contact with
the surface under inspection.

• The Model APS Holiday Detector is now ready to turn on.

• Turn the instrument ON by holding the safety switch handle firmly against the

instrument handle. (Instrument handle has rubber grip), then pressing the “ON”
button.

NOTE: The instrument will turn OFF when the safety handle is released.

• Use push buttons to select the HIGH or LOW range. Remove the dust cover with
the supplied screwdriver, and adjust the voltage setting, using the digital display for
reference. The instrument must be ON for this operation.

• The instrument will “remember” the last HIGH or LOW and voltage setting
selected, after being turned OFF and then ON again.
