DeFelsko PosiTector SPG 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.
PosiTector SPG probes include a 60˚ (ASTM D 4417 B) or 30˚
(Australian Standard AS 3894.5) angle tip (50 µm/2 mil radius) with
a measurement range of 0 to 500 µm (20 mils).
PosiTector SPG CS probes measure the profile of textured
coatings up to 1500 µm (60 mils) with a 500 µm (20 mil) radius
60˚angle tip.
PosiTector SPG TS probes measure concrete surface profile up
to 6 mm (250 mils) with a 500 µm (20 mil) radius 60˚angle tip.
Additionally, the PosiTector body accepts a wide variety of
probe types including magnetic, eddy current and ultrasonic
coating thickness, surface profile, hardness, salt contamination
and ultrasonic wall thickness probes.

Calibration
Instrument calibration is typically performed by the manufacturer.
All probes include a Certificate of Calibration.
Verification of Accuracy
Instrument accuracy is verified using the included metal shim and
glass zero plate. Ensure that the glass plate and shim are clean
and dirt free before use.
Place the plate onto a stable, flat surface. Take several
measurements. If the average is greater than ±5 µm (0.2 mil),
Zero (pg.3) the Gage.
Next, place the metal shim over the glass plate and measure
ensuring the probe needle touches the glass plate in the area
