7. HOW TO USE THE PROBE TO VERIFY THE PASSIVATION
1. Connect the probe to the external unit using the 4 pin cable supplied. (Fig. 4).
2. Unscrew the tip protector and place it on the refilling cartridge compartiment cover (Fig. 5).
For optimal results clean the area to be tested to remove residue and dust, to keep the tip of
3. Place the tip of the test probe on the area to be tested and the ground in contact with metal
4. Maintain the contact in position for the entire duration of the test (Fig. 6)
5. After testing, remove any residual electrolyte solution from the test area, using a humid cloth.
NOTICE: It is well known that where a welding process occurred the heat treatment altered the passivation of the
stainless steel, forming a layer of not protective oxides, slug and iridescence. It is not recommended to use the
tester in this areas, without prior cleaning, as they may cause false results due to the dielectric behaviour of the
not protective oxides and slug, risking to irreparably pollute the tip and therefore distort the subsequent readings.
