PLEASE READ THESE INSTRUCTIONS CAREFULLY PRIOR TO
USING THE 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! If you have a
pacemaker or other life critical electronic medical device DO NOT use this device.
Only trained and responsible personnel should operate high voltage equipment.
Display warning labels prominently prior to and during testing. Portable holiday
detectors are designed to operate and maintain an electric current output well
below levels which could cause injury. However, you may experience a mild shock
if the test electrode or ground is touched while the equipment is activated. Wear
rubber or plastic gloves and non-conductive footwear to 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 void of tears and holes and are in good condition.
Use of Portable Holiday Detectors is limited to finding defects in insulating
materials. Testing should be conducted clear of personnel not involved in the
testing procedure. Personnel operating Portable Holiday Detectors should
be aware of the safety limitations imposed by their environment at all times.
Operator should have an assistant to ensure that 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.
DANGER! IF YOU HAVE A PACEMAKER DO NOT USE THIS
DEVICE.
DO NOT CUT THE GROUND CABLE TO A SHORTER LENGTH.
CAUTION! DO NOT TOUCH THE BARE GROUND WIRE WHEN
THE DETECTOR IS TURNED ON.
WARNING! DO NOT USE WHEN RAINING. If it is raining then
there is a safety concern for the operator. Pure water is non-
conductive, but almost any contaminant will cause water to become conductive
(dust in the air or salt from an operator’s hands). If conductive water covers the
wand (the black plastic part of the detector where the electrode is attached) and
the orange case then the operator will become the return path for the high
voltage. While this is NOT LETHAL, it does hurt. Also the unit may become
damaged.
If it isn’t raining, but the coating surface is wet, the problem becomes one
of accurately locating the coating defect (holiday). Again, the water will
conduct the electricity and you may get false holiday indications many feet from
the actual holiday(s). In this case it is recommended that you dry the testing area
prior to inspection.
CAUTION! DO NOT USE AROUND SENSITIVE
ELECTRONICS OR RADIO EQUIPMENT. When in standby the
SPY®Model 785 / 790 Pulse Holiday Detector will generate radio frequency
emissions which are within the limit defined by the Electromagnetic Compatibility
Directive. Due to its method of operation however, the SPY®Model 785 / 790
Pulse 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.
ELECTRODES / ACCESSORIES: It is imperative for the accurate operation of
the unit that electrodes (Spring & Brush) and accessory attachments (Spring &
Brush Wands & Ground Cable) be kept clean and free of dirt and debris. Please
clean with a damp cloth before storing them for future use.
