Wet Sponge Holiday Detectors are used for the detection of discontinuities
(holidays) in thin film coatings (1-20 mils) of paint, epox y or any non-con ductive
material applied to a conductive material. This t ype of detector uses 67.5 volts
DC for a test voltage, w hich is applied to the test surfac e via a wet sponge. The
fluid media (usually water) in the wet sponge fills the voids in the surface to be
tested and allows low current (micro-amps) to flow into any ho lidays in the test
area. The current moves through the holiday and into the conductive substrate
which activates a horn to indicate the presence of the holiday.

STEP 3. CO NNECTING T HE GROUND CABL E. The ground cable at tach
point is on the backside of the 670, untwist the black knob to expose the hole in
the ground connector, thread the ground wire through the hole and then tighten the
black ground connector knob tightly with your hand only.
CAUTION! DO NO T TOUCH Make sure the switch is in the OF F position
prior to connecting any accessory.
STEP 1. CONN ECTING THE E LECTRODE WAND. Screw the wand onto the
base of the 670 holiday detector and firmly tighten with your hand only.
STEP 2. CO NNECTING T HE ELECTROD ES. The flat sponge ele ctrode comes
standard with t he 670 and is already attac hed to the wand. However, if you purchased
the optional roller sponge electrode just unsc rew the flat sponge electrode from the
top of the wand and screw on the optional roller sponge elec trode. You can adjust
the flat sponge o r roller sponge electrode by simply holding the knurled k nob firmly
and twisting the electrode to the desired position.
CAUTION! DO NO T TOUCH THE ELECTRODE WHILE T HE DETECTOR
IS OPERATING.

PROPER GROUNDING. Make sure the ground c able is uncoiled and
extended.
DIAGRA M 1: Shows the method of completing a circuit is by connecting
the ground cable of the 670 holiday detector to the unco ated part of the metal
substrate of the test piece using the alligator clip. This allow s the circuit to
complete directly from the detector through the holiday into the substrate back
into the detec tor.

For a range of optional accessories and spare parts that enhance and
expand the capabilities of the SPY 670 SPY offers an Optional 670
Inspection Kit. See the Accessories page in this manual or call your SPY
distributor or manufacturer to order.
STEP 5. (OPT IONAL) CONNECTING THE SHOULDER STRAP.
Attach the strap clips tabs on each side of the 670 detector. Adjust strap
for comfort. The strap comes with the optional 670 Inspection Kit which
offers the option of attaching a light weight foam handle wand to use
while operating rather than holding the weight of the complete unit.
STEP 6. (OPTIONAL) CONNECTING ADDITI ONAL 14.5”
WAND EXTENSION RODS. With the 670 turned off simply unscrew
the electrode from the wand and screw on the number of 14.5” wand
extensions you need for the job, once complete add the electrode back
to the end of the wand. The optional 670 Inspection Kit comes with
2-14.4” wand extensions to give the 670 detector added length for hard
to reach test areas
STEP 7. (OPTIONAL) CONNECTING WAND LEAD CABLE.
With the 670 turned off disconnect the wand from the base of the unit,
screw the knurled portion knob of the wand lead cable to the base of the
unit and plug the other end of the wand lead cable to the end of the foam
handle wand. Unscrew the electrode from the stock wand electrode and
screw it on the foam hand wand.
The NEW SPY® Model 670 Wet Sponge Holiday Detector operates on
a single 9 volt alkaline battery. Unit output voltage is 67.5 volts DC. This
voltage makes the detector highly sensitive and accurate.
STEP 1: Make sure the detector switch is in the off position.
STEP 2: The battery compartment is located on the left side of the unit,
using the notch on the bottom of the batter y compartment lift up and
pull out to slide the battery tray out.
STEP 3: Insert a new 9V battery into the battery tray and push the
battery tray firmly back into the unit making sure it locks back into place.
If the battery discharges to a low level the detector will begin to tone
continuously, at this point the detector is not properly detecting holidays
and the battery should be changed to a new 9V battery.

testing
instructions
No Signal adjustment is necessary with the 670 Wet Sponge Holiday
Detector. The unit can easily be tested by means of the test buttons
located on the front operating panel.
The test is performed by turning the 670 on and by pressing the 80 Kohm
button, the signal will become active causing the horn and LED to be
activated. Release the 80 Kohm button then press the 100 Kohm, the
signal should NOT activate the horn and LED. This test indicates the unit
sensitivity is within calibration.
670 operation
STEP 1: Insert a new 9V battery in the battery box and push the
battery box firmly back into the unit making sure the battery box locks
back into place.
STEP 2: Attach the electrode wand and electrode.
STEP 3: Attach the ground cable to the conductive substrate of the test
surface (the uncoated bare metal portion of the surface). See Diagram
1 on page 8.
STEP 4: Wet the electrode sponge with clean tap water to where it is
damp or moist to the touch and apply SPY
®
wetting agent.
STEP 5: Keeping the detector away from the test surface and turn the
detector to the on position.
IMPORTANT! While the electrode sponge must be damp or
moist to the touch it should not be saturated to the point water
is running from the sponge. This can result in the water migrating and
causing the current to flow away from the sponge down the test surface
to holidays further down the test sur face or even on the support surface
causing false holiday indications.
IMPORTANT! When the coating thickness is between 11– 20
mils, a low sudsing wetting agent such as KODAK Photo-flo
™
should be applied to the water (test media). This will allow for a lower
surface tension, which will help the test media to penetrate the thicker
coatings. You can order Kodak Photo-flo
™
direct from SPY®.

pi clt d.co mpi clt d.co m

STEP 6: Place the electrode sponge on the coated surface and begin
passing the sponge across the surface (See Diagram 2 Below). Several
passes should be made over the test area to ensure that moisture has
penetrated any possible holiday. If the sponge passes across a pinhole
in the coated surface an audible horn from the detector will begin to
sound and the red light on the control panel will light up. The audible
and visual alert will stop once the electrode moves away from the
pinhole. For more precisely locating the holiday use the corner of the
sponge in the area the holiday occurred.
IMPORTANT! Care should be made to ensure that the sponge
stays as clean as possible. Dirt or other contamination of the test
surface adds resistance, which impedes the current flow capability of
the sponge. This can result in missing holidays in the test piece.

Electrode types
The Model 670 uses cellulose sponge electrodes that vary in form and
size and fit a wide range of coating inspection projects. If we don’t carry
it we can custom build an electrode to fit your project needs.
Different types of electrodes can be used with different units. The most
common electrode is a flat sponge electrode wand. The Model 670
wand utilizes a 2”x 4” x 8” (51mm x 102mm x 203mm) size flat sponge.
Roller sponges are also available to increase the surface area in contact
and the speed at which the test piece can be tested.
