DeFelsko PosiTector RTR Guía Rápida página 3

When powered-up, the PosiTector automatically
determines which probe is attached and does a self-
check.
To disconnect a probe from a body, slide the plastic probe
connector horizontally (in the direction of the arrow) away
from the body. Reverse these steps to attach a different
probe. It is not necessary to power-down the Gage when
switching probes.
The PosiTector gage body accepts a wide variety of
probe types including magnetic, eddy-current and
ultrasonic coating thickness, surface profile,
environmental, Shore hardness and ultrasonic wall
thickness probes. See www.defelsko.com/probes
Press-O-Film provides a simple way to obtain an impression of
a surface for analysis. It consists of a layer of crushable plastic
micro foam affixed to a 50.8 µm (2 mil) incompressible polyester
film. When compressed against a roughened surface, the foam
collapses and acquires an accurate impression, or reverse
Placing the compressed tape (replica) into the PosiTector RTR
gives a measure of the average maximum peak-to-valley height
of the surface roughness profile. The Gage automatically subtracts
the thickness of the polyester film from all measurements.
Optical Grade Press-O-Film Replica Tape
For improved optical resolution and to reduce optical artifacts, this
special grade of replica tape is available for use with the PosiTector
RTR-P. It provides better images, consistent peak density values
and higher quality SDF surface data files than conventional Press-
O-Film replica tape. It is available in both Coarse (C) and X-Coarse
(XC).

to accommodate measurements in
different profile ranges.
