DeFelsko PosiTector SPG Gebrauchsanweisung Seite 5

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, environmental, hardness,
salt contamination, gloss, and ultrasonic wall thickness probes.

Calibration & Verification of Accuracy
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. 4) the Gage.
Next, place the metal shim over the glass plate and measure,
ensuring the probe needle touches the glass plate in the area
between the shim's "legs". The average of several
measurements should be within the combined tolerances of
both the Gage and the shim.
If not, see Returning for Service (pg. 11).
