Calibration Settings
Calibration, Verification and Adjustment
Three steps ensure best accuracy:
1. Calibration: typically performed by the manufacturer. All probes include a Certificate
of Calibration.
2. Verification of Accuracy: typically performed by the user on known reference
standards such as the included plastic shims, test block or optional coating thickness
standards.
3. Adjustment - to a known thickness, if necessary.
Calibration is the controlled and documented process of measuring traceable calibration
standards and verifying that the results are within the stated accuracy of the Gage.
Calibrations are typically performed by the Gage manufacturer or by a certified
calibration laboratory in a controlled environment using a documented process.
Verification is an accuracy check performed by the user using known reference
standards. A successful verification requires the Gage to read within the combined
accuracy of the Gage and the reference standards.
Adjustment, or Calibration Adjustment is the act of aligning the Gage's thickness
readings to match that of a known reference sample in order to improve accuracy of a
gage on a specific coating.
NOTE:
The PosiTector 200 measures most polymer coatings accurately out-of-box with no
adjustment required.
Zero
The probe must be periodically zeroed to compensate for both temperature and probe
wear effects. Before using, allow the probe to reach ambient temperature. Wipe the
probe clean of couplant.
If measurements will be made in extreme hot or cold temperatures, it is recommended
to Zero the probe in the working environment. If measurements will be made on rough
substrates, it is recommended to periodically Zero the probe to compensate for wear.

Page 7
Cal Reset
Restores the gage back to factory calibration and range settings. The factory calibration
icon will appear on the display.
Cal Lock
When enabled, the Cal Lock icon appears and the current calibration is locked to
prevent further user Thickness adjustments.
Polyurea
(PosiTector 200 D probes only)
When enabled (default), the Gage loads a pre-programmed calibration adjustment
optimized for measurement of polyurea coatings. Polyurea will appear on the upper
right corner of the display.
NOTE:
Measuring range in Polyurea mode: 50 - 5000 um (2 - 200 mils)
Set Range
The measurement range of each probe can be changed depending on the specific
application or the expected thickness range of the coating system.
For most applications, the default range values do not need to be adjusted. But some
conditions, like surface roughness, may cause the Gage to display very low or
non-repeatable readings. In this case, the low range may be increased to cause the
Gage to only display readings above the Lo value set by the user.
To adjust Set Range values:
1. Select Lo or Hi.
2. Use the (-) (+) buttons to decrease/increase the displayed value.
IMPORTANT:
The PosiTector 200 will ignore any readings outside the selected range. If the coating
thickness is outside this range, incorrect or dashed readings may occur.

Page 8
Thickness
The PosiTector 200 measures most polymer coatings accurately out-of-box with no
adjustment required.
To determine if an adjustment is necessary, select a coating sample of known thickness
as close as possible in composition to the intended application. For best results, the
thickness of the sample should be equal to or slightly greater than the maximum
expected thickness of the coating to be measured.
Measure the coated sample. If the average of a series of measurements on the sample
is not close to the known thickness:
1. Use (-) or (+) to decrease/increase the displayed measurement thickness value to
match the known thickness of the sample.
2. For Advanced models with multiple layers selected, use the Down button to select the
next layer and adjust as necessary.
3. To save adjustments, use the Down button to highlight OK and press the center
navigation button.

Setup
Set configuration options for the Gage.
Set Clock
All measurements are date and time stamped (24 hour format) when stored into
memory. It is therefore important to keep both the date and time current using this menu
option. Use the Up and Down buttons to scroll, and the (-) and (+) buttons to adjust
value. The Gage’s date and time can also be viewed in Gage Info and on top of the
main menu.
NTP
Enables automatic time synchronization with a remote server over WiFi using the NTP
(Network Time Protocol).
Enter a NTP Server address and TZ (Time Zone) details. The PosiTector uses POSIX
format to set the time zone.
Eastern Time in the USA is input as the following:
EST5EDT4,M3.2.0,M11.1.0
From left to right:
- EST5 is the time zone name and offset from UTC
- EDT4 is the daylight savings time zone name and offset from UTC
- M3.2.0 is the start of EDT. ‘M’ specifies that the date will follow a ‘Month.Week.Day’
format. 3.2.0 is the third month, second week, first day (Sunday)
- M11.1.0 is the end of EDT. ‘M’ specifies that the date will follow a ‘Month.Week.Day’
format. 11.1.0 is the eleventh month, first week, first day (Sunday)
Detailed NTP instructions available at: www.defelsko.com/NTP
Reset
Restores factory settings and returns the Gage to a known condition. The following
occurs:
All batches, stored datasets, batch names and screen captures are erased.

Touch
Allows the touch screen functionality to be disabled. All gage functions can also be
controlled using the navigation buttons.

Page 12
Backlight
Selects display brightness (Sun, Normal or Night). If Auto Dim is enabled (default), the
display dim slightly after a period of no activity to conserve battery life. Press the Down
button to brighten the display.
Flip Lock
Disables the Auto Rotate feature by locking the display in its current orientation.
Graphics
When selected, the Gage displays a graphical representation of the ultrasonic pulse as
it travels through the coating system.
As the probe is depressed and the ultrasonic pulse travels through the coating system,
the pulse encounters changes in density at the interfaces between coating layers and
between the coating and the substrate.
These interfaces are depicted by a peak. The greater the change in density, the higher
the peak. The more gradual the change in density, the greater the width of the peak.
For example, two coating layers made of essentially the same material and blended
would result in a low, wide peak. Two materials of very different density and a
well-defined interface would result in a high, narrow peak.
The PosiTector 200 has the ability to measure the thickness associated with either the
highest peak(s) or the deepest peak(s), depending on whether Max Thick Mode is
enabled. The reported peaks will be indicated with small red triangles on the graph.
Use the Up (move left) and Down (move right) buttons to highlight icons on the graphic
display.
Max Thick Mode
By default, the PosiTector 200 reports a coating thickness result associated with the
loudest ultrasonic echo (the highest peak in Graphics Mode), within the set range. This
loudest echo often represents the total coating thickness above the coating-substrate
interface. When multiple layers are selected, the loudest echoes are reported as
individual layer thicknesses.
In some applications, surface roughness and/or coating layers with significant density
differences near the surface can result in a louder ultrasonic echo than the one from the
coating-substrate interface, resulting in a lower than expected reading. While the Lo

Page 13
Range can be adjusted to ignore these loud, unwanted echoes, this sometimes requires
that the range be adjusted too close to the expected coating thickness for reliable
measurement.
When Max Thick Mode is selected, the PosiTector 200 reports the echo or peak
associated with the deepest interface in the coating system, instead of the loudest. This
is often more effective at reporting the total coating thickness above the substrate
interface, and eliminates the need to adjust the Lo Range.
Since there will inevitably be some small echoes from within the substrate, only echoes
above a pre-set loudness threshold will be reported. This threshold can be adjusted
from within Graphics Mode. When multiple layers are selected, the layer thicknesses
associated with the deepest ultrasonic echoes are reported.
NOTE:
Max Thick Mode is not recommended for thin metal substrates less than 2.54 mm (100
mils) thick, or substrates such as composites and fiberglass.
