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 surface 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
