Inspect the probe for damage to the protective casing, which can affect scan accuracy.
Best for tight spaces, corners, and areas with highly congested reinforcement.
Place the specialized (or calibration spacer block) between the probe and the concrete surface. Take a second reading with the spacer in place. proceq profometer 4 manual
: Traditional models typically feature a clear needle-meter or LCD for real-time signal strength and cover depth. Audible Locating Aids
: Turn the instrument on and verify the battery level indicator is in the functional zone. Inspect the probe for damage to the protective
: For accurate cover readings, the user typically inputs the expected diameter of the rebar being measured.
Check the battery levels before starting to ensure accurate results. Take a second reading with the spacer in place
: The strongest signal is achieved when the center line of the probe is parallel to the bar. Maintenance and Care
Hold the search head in the air, away from any metal, and press the ZERO button. This accounts for environmental interference.
: The exact center line of the rebar is located at the point where the signal strength peaks and the indicated cover depth reaches its absolute minimum . Mark this spot on the concrete. Step 4: Measuring Concrete Cover Depth
