PosiTector Roughness Thickness Gauge RTR Rough Thickness Testing
Machine Tester
Instroduction
The PosiTector RTR roughness thickness gauge is used to measure the
height of the peaks and valleys formed on the surface of the
reproduction tape (reproduction paper) through the imprinting
process. The instrument is simple and convenient to test, can be
operated with one hand, and has built-in temperature compensation
to ensure measurement accuracy. The reset function allows users to
quickly restore the factory settings. The instrument screen is
equipped with a liquid crystal display with wear-resistant and
corrosion-resistant functions, and the casing is equipped with an
impact-resistant rubber protective cover, which can effectively
protect the instrument from acid, oil, water, solvents, and dust.
During the testing process, the instrument can continuously display
and update the average value, standard deviation, maximum value,
minimum value, and the number of measurements. Through the USB
interface, the data can be conveniently output to a computer or
printer.
Measurement method
Preparation of the test surface:
Select a representative area for measurement. Clean the surface for
testing. DeFelsko suggests using a cleaning putty to remove dust,
debris, or residual sandblasting media from the surface. Firmly
press the putty onto the surface with your fingers and remove it.
Grinding the replica tape:
Choose a suitable range of the replica tape based on the target
outline (coarse or X-coarse). Refer to the instructions for
replicating the tape. There is a magnetic tape copy with adhesive
on the back of the single side of the pull-resistant anti-stick
paper. The "target center" circle on paper A should be kept on the
release paper (which is not used for measurement). Use the round
end of the included stainless steel polishing tool to firmly
compress the copy film. It is suitable for circular and XY friction
movements to produce a replica with a uniform pebble-like
appearance with sufficient pressure. It usually takes 30 to 60
seconds to fully compress all parts of the film on most surfaces.
Generally, excessive compression is safer than insufficient
compression. After polishing, remove the magnetic tape of the
replica from the surface.
Preparing PosiTector RTR:
Clean the measurement surface (measuring base) using the included
cleaning card. Clear dust particles and remaining tape adhesion by
pressing the card several times while firmly pressing the two probe
buttons. Press the center navigation key on PosiTector RTR. An
image appears indicating that the probes need to be zeroed. Press
both buttons simultaneously, and the probe will slowly measure
while the instrument emits a beep and the arrow points outward. Do
not place any items during this process. The measurement includes
checking the gasket to verify accuracy. Ensure the correct grade of
the replica tape, C or XC, is displayed in the upper left corner of
the LCD screen.
