6000 FNDS probe

PosiTector

for Duplex Coatings

Addendum to Instruction Manual v. 7

When attached to either a PosiTector Standard or Advanced body, the PosiTector 6000

FNDS probe measures the individual thicknesses of both the paint and the zinc layers

in a duplex coating system with a single reading.

Duplex coating systems use a combination of two corrosion protection systems –

typically paint or powder coating over galvanized steel (hot-dip, electro or zinc spray

metallizing). The resultant corrosion protection is superior to either protection system

used independently.

Duplex Mode

In Duplex mode, the Gage utilizes both magnetic (ferrous) and eddy current (non-

ferrous) principles simultaneously to calculate and display the individual paint and zinc

layer thicknesses. The magnetic principle is used to measure the combined paint/zinc

thickness over the ferrous substrate and the eddy current principle is used to measure

the paint thickness over the non-ferrous zinc coating. The zinc thickness is calculated

by subtracting the paint thickness from the combined paint/zinc thickness

measurement.

Page 2 N = Paint Thickness Zn = Zinc Thickness When enabled (default), the Gage will display two measurement values (as shown above). To disable, uncheck Duplex within the Setup Menu. Alternatively, press the Up navigation button to toggle Duplex On/Off (when Memory is OFF). When disabled, the Gage will operate like a conventional combination ferrous/non- ferrous instrument (similar to the PosiTector 6000 FNS probe).

PosiTector 6000 FNDS probes are factory calibrated and perform an automatic self- check each time a measurement is taken. For many hot-dip galvanized applications, no further adjustment is necessary from the factory calibration.
