Probe Type
Select between
Rod, One Wheel and Four wheel
depending on the
electrode connected
Grid X Spacing
It determines the horizontal width of the measured cell (wheel electrode)
or the horizontal distance between measured points (rod electrode).
Grid Y Spacing
It determines the vertical distance between two adjacent measuring lines
(wheel electrode) or the vertical distance between measured points (rod
electrode). In case of four wheel electrode it should be set equal to the
distance between the wheels (150 mm, 250 mm or custom).
Enable Grid Limits
If set the user can define the maximum extent of the investigated area.
Unit
Select
Metric
or
Imperial
Measurement Path
It determines the direction of the measuring sequence when using the
rod electrode (Left / Right / Up / Down)
Coarse Grid Factor
It determines how many times the coarse grid is larger than the XY-Grid
already defined. Example: when distance between measurement points
in the XY-Grid is set to 150 mm and the Coarse Grid is set to 5, the
distance between measurement points in the coarse grid is 5x 150 =
750 mm. This is useful for carrying out an initial sweep and switching to
a fine grid later for detailed investigations.
Auto Save
If selected, then measured values of < -50mV will be acquired automati-
cally once the value has stabilized. If automatic measuring is not selected
then values have to be acquired manually. In both cases, values > -50mV
have to be acquired by manually.
Direction of Next Line
•
Select
Manual
if the next line begins at the same x coordinate of the
end point of the previous one, keeping the same direction.
•
Select
Inverted
if the next line begins at the same x coordinate of
the end point of the previous one, inverting direction.
•
Select
Return to start on new line
if all the lines start at zero posi-
tion, in the same direction.
At the beginning of each line (for the first 100 cm / 40 inch) the direction as
previously set will be displayed on the screen by four flashing arrows and
the user will have the option to invert it manually (see “4.2.3. Corrosion-
Scan Mode”).
Potential Max Threshold (Highest)
It defines the highest (most positive) potential value associated with the
display color palette.
Potential Min Threshold (Lowest)
It defines the lowest (most negative) potential value associated with the
display color palette.
Potential Range Palette
Multicolor / Red / Blue / Gray
Minimum Passive Limit
It defines the lowest (most negative) potential value associated with a
passive, non corroding area. It is displayed as a green vertical cursor in
the Cumulative Distribution View and it defines the areas displayed in
green in the Chipping Graph View (see “4.2.4. Corrosion Display Views”).
