PRODUCT INSTRUCTIONS

DESCRIPTION

The Model M/2 H ol id a y De t ec tor is a highly sensitive d evic e d es igned to locate holid a ys ( pi n hol es, voids ,
etc.) in thin film protective coatings of relatively high electrical resistance when such films are applied to the
surface of mater ial of low e lectric al res istance . In t hese ap plic ations, s uch as pai nted m etal sur faces , the
Model M/2 Holiday Detector will locate these points very accurately with an audible and visual signal. This
method of inspection of thin film is a non-destructive test and will not injure the protective coating.

OUTPUT VOLTAGES

The M/2 has multiple volta ge outputs tha t can be sele cted. T hese outputs hav e been deter mined to meet
varying international standards regarding the use of the equipment. The Model M/2 Low Voltag e (Wet
Sponge) Holiday Detector is designed to meet or exceed the requirement of the following standards (Partial
List):
NACE RP0188, SP0188, TM0384
ASTM D 5162-A, G6, G62-A
ISO 8289, 14654, 14655, 14656, 15741, 16967, 29601
AUSTRALIA AS 3894-2
JAPAN JIS 6766

EQUIPMENT
The Model M/2Holiday Detector consists of a portable battery powered electronic instrument, a wand

handle, and sponge assembly (open ce ll sponge ships c ompressed, will expand with water), and ground
wire. The instrument is housed in a sturdy plastic case with provision for attachment of optional (not
included) headphones .

The detector is a “non-d estructive wet sp onge” type holida y detector. The b asic electronic des ign of the
Model M/2 Holiday Detector is that of a ver y sensiti ve circ uit whic h is ener gized by on e 9 v batter y. When
current of 500 or 700 (+/- 10/%) micro-amperes flows in the circuit, an audible and visual signal is actuated.

The test lead wire used in the ground wire can handle a minimum of 100 milliamps at 100 volts. If
replacement or addit ional wire is need ed, make sure it m eets these requirem ents. Up to 100’ len gth of
ground wire does not ad versely affec t the detectors oper ation, in mos t cases. If adding add itional ground
wire, 14 AWG stranded or equivalent is recommended.

The exploring electrode is open-cell sponge material and is conductive when saturated with a wetting
solution. The sponge electrode is attached to the non-conducti ve wan d hand le b y means
of the bolt with knob, plastic sponge holder and backing plate.
The wetting solution should consist of potable tap water and a wetting agent.

The ratio of one (1) ounce agent t o one (1) gal lon tap wat er is recomm ended. Tinker & R asor WATER-
WETTER© is a non-sudsing wetting agent, av ailable in 8 oz. bottles, f actory direct or through s tocking

distributors.
