Memory
The PosiTector RTR Standard has internal memory storage for recording measurement
data. Stored measurements can be reviewed on-screen or downloaded to a computer.
Measurements are date and time-stamped. Store up to 1000 readings (per probe) into a
single batch.
The memory icon appears when the Gage is set to store measurement data.
View
Use the Up or Down buttons to scroll through information, statistical summary, and a list
of each reading in the currently opened batch. Press the center navigation button to
exit.
Off
Turns memory off and stops recording (stored readings remain in memory)
On
Turns memory on and begins recording measurements.
Clear
Removes all stored readings from memory.

Statistics
(PosiTector RTR-H probes only)
Menu option for configuring Statistics and HiLo Alarm modes.
Statistics
Statistics mode continually displays/updates average, standard deviation, min/max
thickness and number of readings while measuring.
When selected, the statistics icon and statistical summary will appear on the display.
Ignore the last measurement by pressing the (-) button. Press (+) to clear statistics.
Clear
Clears all on-screen Statistics and HiLo tabulations.
HiLo Alarm
Allows the Gage to visibly and audibly alert the user when measurements exceed
user-specified limits.
When HiLo Alarm is selected, the current Lo setting is displayed. Adjust using the (-) or
(+) buttons. Select Next to accept this value. The current Hi setting is now displayed.
Repeat to adjust the Hi setting.
Each measurement will be compared to the defined Hi and Lo limits. The Gage beeps if
results are within those limits. A single low tone will sound if the reading is below the Lo
limit, and a high tone if it is above the Hi limit. Press (+) to clear HiLo readings.
The Statistics icon will appear on the display.

Calibration Settings
Calibration and Verification
Calibration
Gage calibration is typically performed by the manufacturer or accredited lab. All
PosiTector RTR probes include a Certificate of Calibration.
Verification
Ensure that the probe has been cleaned with the included cleaning card and that the
probe has been zeroed.
Verify accuracy of the digital micrometer measuring system.
Place the PosiTector RTR Check Shim into the probe opening. The average of several
measurements should be within the combined tolerance of both the Gage and the shim.
If not, the Gage may need to be returned for service.
The check shim is specifically intended for all PosiTector RTR probes. The Gage is
designed to measure burnished replica tape within a limited measuring range and
automatically subtracts 50.8 microns (2 mils) from height measurements to account for
the incompressible polyester film. Therefore plastic shims intended for other instruments
such as coating thickness gages will not be measured properly.
Verify the optical measuring system
(PosiTector RTR-3D probes only)
Place the Peak Density Check Tape into the probe opening. The peak density (Spd)
result should be within tolerance specified on the tape. If not, the Gage may need to be
returned for service.
Ignore the peak height (H) result when using the Peak Density Check Tape.
Zero
The probe should be zeroed regularly to ensure best accuracy. The user will be
prompted to zero the probe every time the Gage is powered up. The Zero menu item
allows the procedure to be performed at more regular intervals. It is particularly useful
during long measurement sessions.
Page 6
Important:
Clean the probe with the included cleaning card before performing a probe zero.
Simultaneously press and hold both probe buttons firmly until the Gage beeps and the
arrows point outward. Do not place anything in the measurement opening during this
procedure.
SHORTCUT:
Simultaneously press and hold both probe buttons firmly until the Gage beeps and
displays 0. This can be performed from the main measurement screen without having to
access the menu.
Tape Grade
Selects a replica tape grade. Required when Linearize mode (HL) is ON.
C - Coarse
XC - Extra Coarse (default)
NOTE:
Coarse Minus and X-Coarse Plus grades are not supported in Linearize mode since the
only function of these two grades is to improve upon the accuracy of C tape at its low
end and XC tape at its high end, something the PosiTector RTR H will automatically do
when measuring HL. When Linearize mode is OFF, the PosiTector RTR H will measure
all grades of replica tape just like a conventional spring micrometer.
Linearize
This is the default measurement mode. Linearize mode is ON when this box is ticked
and the HL appears on the display.
An undesirable characteristic of replica tape is that measurements made with analog
spring micrometers are most accurate near the middle of each grade's range and least
accurate at the outer ends of each grade's range. That is why two other grades, Coarse
Minus and X-Coarse Plus, are used to check and, if necessary, adjust measurements at
the lower and upper ends of the primary range of 20-115 microns (0.8-4.5 mils).
Inside the primary range, the upper end of the Coarse grade range and the lower end of
the X-Coarse grade range share a 38 - 64 micron (1.5 -2.5 mils) overlap region. Current
Testex instructions describe a relatively complicated and time consuming procedure
(the average of one reading using Coarse grade and one reading using X-Coarse
grade) that is used to knit the Coarse and X-Coarse subranges together to achieve
Page 7
reasonably accurate readings over the primary range. This method is a compromise
between accuracy and ease of use.
When the Linearize box is NOT ticked, the PosiTector RTR displays a height value of H
comparable to the value an analog spring micrometer would display after the 50.8
microns (2 mils) of incompressible polyester film has been subtracted. In other words, it
is the average of the maximum peak-to-valley distances obtained by measuring the
thickness of the replica tape without any correction.
When the Linearize box IS ticked, the PosiTector RTR displays a more accurate
peak-to-valley height measurement HL that has been adjusted for the non-linearity of
replica tape. There is no need to average 2 or more replicas from different grades of
tape AND there is no need to subtract the 50.8 microns (2 mils) of incompressible
polyester film. Ensure the proper tape grade, C or XC, has been selected and appears
in the upper left corner of the display.
During measurement, if the linearized measurement falls outside of the selected tape
grade's range, the Gage will suggest a more suitable tape grade to perform the
measurement.

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.
Reset
Restores factory settings and returns the Gage to a known condition. The following
occurs:
All batches, batch names, and screen captures are erased.
Menu settings are returned to the following:
Memory = OFF
Statistics Mode = OFF
Display = None
Bluetooth = OFF
WiFi & Access Point = OFF
USB Keyboard & Stream = OFF
Bluetooth BLE Keyboard = OFF
Tape Grade = XC
Linearize = ON
Auto Dim = ON
Perform a more thorough Hard Reset by powering down the Gage, waiting several
seconds, then simultaneously holding both the center navigation and (+) buttons until
the Reset symbol appears. This returns the instrument to a known, out-of-the-box
condition. It performs the same function as a menu Reset with the addition of:
Bluetooth Pairing info is cleared. Menu settings are returned to the following status:
Units = Microns
Flip Lock = OFF
Sound = Medium
Touch = ON
