Introduction
Introduction
The PosiTector PC Powder Checker is a hand-held,
non-contact Coating Thickness Gage that uses an airborne high
frequency ultrasound to analyze coating powder applied to rigid
substrates to calculate and display a predicted cured thickness.
The Gage consists of an Advanced body and a Powder Checker
(PC) probe that communicate with each other via wireless
technology. They must stay within 10 meters (30 feet) of each
other while measuring. A rubber holster with belt loop allows the
PosiTector body to stay with the operator while measuring.

To preserve battery life, the PosiTector body and
PC probe power down after approximately 5 minutes of no activity.
All settings are retained.
1. POWER-UP both units (probe first).
a) Power-up probe by pressing the button.
b) Power-up PosiTector body by pressing the center
navigation button.
A beep and the letters “PC” will display on the upper left corner
of the PosiTector LCD. This indicates both units are ready to
measure.
2. ZERO the probe (pg 8)
3. ADJUST to the specific powder if necessary (pg 10)
4. MEASURE the applied powder (pg 5)

NOTE:
Wrist Strap
We recommend attaching and wearing the
supplied wrist straps for both the PosiTector
body and PC probe. 1

Protective Lens Shield
The LCD is covered with a thin plastic film for protection against
fingerprints and other marks during shipment. This film, while
usually removed before using the Gage, can be left in place to
protect against paint overspray or debris. Replacements can be
purchased.

PosiTector Body
The PosiTector body accepts a number of probe types including
magnetic, eddy current and ultrasonic coating thickness, surface
profile, environmental and ultrasonic wall thickness probes.

Wireless Powder Checker probes:
The PosiTector PC wireless probe connects to all Advanced
PosiTector bodies. See Powder Probes (pg 26) for connection details.
Physically connected PosiTector probes:
To disconnect a probe from a PosiTector body, slide the
plastic probe connector horizontally (in the direction of the
arrow) away from the PosiTector body. Reverse these steps
to attach a new probe.
The PosiTector automatically determines what type of probe
is attached and does a self-check.

Maintenance
The screen at the measuring end of the PC probe can be unscrewed
for cleaning. Accumulated powder should be carefully removed from
the screen by no more than 0.2 MPa (20 - 30 psi) of compressed air.
Do not blow air directly into the probe. Replacement screens are
available.
During power-up a physically connected probe is recognized
when a PC probe is not available (powered-off).
To reconnect to a PC wireless probe (after power-up), select Connect,
within the Connect > Powder Probes menu. (pg 26)
The PosiTector body will automatically connect to an active wireless
PC probe during power-up. PC probe must be turned on.
NOTE:
If a thickness result does not appear after 5 seconds, release the
measurement button and try again. Wait 1 to 2 seconds between
readings.
Small, erratically swinging parts may present measurement challenges.
Steady the part whenever possible. If erroneous readings continually
result, change the measurement strategy by rotating the probe, altering
its alignment to the part, or by measuring a different location on the
part.
For best results use Statistics mode (pg 14) to generate averages.
The average of a series of measurements is often a more meaningful
prediction of cured thickness than a single reading.

Power-up both units. Bring the probe to within 5 cm
(2 inches) of the coating powder.
Press and hold the button. Bring the probe closer to the
powder. While watching the probe display, align the Distance
Paddle with the Distance Target Bar. (pg 5)
While the probe button is depressed, probe distance and angle
should be varied slightly keeping:
(a) the Distance Paddle close to the Distance Target Bar
(b) the Amplitude Indicator at maximum height (pg 5)
Release the button when you hear a double BEEP or see a
thickness measurement on either display.

Amplitude Indicator: Strength of the ultrasonic echo.
A high position indicates good probe orientation relative to
perpendicular. The bar will generally reach higher positions when
measuring thin powder and when the probe is at a 90-degree
angle to the powder surface.
Maximum Amplitude Dot: Marks the highest position the
Amplitude Indicator reached during the current measurement
attempt.
Predicted Cured Thickness Result: When a valid measurement
is calculated, the PosiTector body BEEPS twice and the predicted
cured measurement result is displayed on both the PC probe and
PosiTector body. Continuing to hold the probe button will result in
additional samples being collected.
There are 4 types of displayed measurement results:
43 Predicted thickness result.
0 The collected samples have resulted in a good reading,
but the resultant predicted cured thickness is less than the
minimum range.
++ The collected samples have resulted in a good reading,
but the resultant predicted cured thickness is greater than
the maximum range.
-- An indeterminate or invalid reading.
Wireless Indicator: The symbol indicates the PosiTector body
and wireless probe are communicating properly.
Results Indicator: When the probe is in the proper position and
good samples are being taken, a solid blue dot blinks on the probe
display, the PosiTector body displays a flashing green dot and
emits a high beep. When samples are inconclusive, an "X" blinks
on the probe display, the PosiTector body displays a flashing red
dot and emits a low beep.
Distance Paddle: Graphically represents the distance to the
target. It rises and falls to indicate distance from the probe tip to the
surface of the powder.
Distance Target Bar: The optimum distance for measurement is
18 mm (3/4 inch) between the tip of the probe and the surface of
the applied powder. During measurement, keep the Distance
Paddle close to the Distance Target Bar.

The center button is purposely recessed to help eliminate
unintentional power-up.
When no probe is attached, a limited menu will be displayed.
Connect probe for full menu.

Gage functions are menu controlled. To access the Menu,
power-up the PC Probe and PosiTector body, then press the
center navigation button.
Below is a sample menu for a PosiTector PC:
Some buttons have a tick box to their
right to indicate current status. An empty
box indicates that feature is not active.
