By utilizing the original manual to calibrate your device correctly and keeping the unit well-maintained, the Proceq Profometer 4 will continue to serve as an exceptionally precise tool for structural concrete diagnostics.
The most reliable source for equipment documentation is the original manufacturer. Visit the official website of (formerly Proceq). Navigate to their "Downloads," "Support," or "Legacy Products" archive. They frequently maintain PDF libraries of older instruction manuals, technical specifications, and product brochures for free download. Utilize Authorized NDT Equipment Distributors
Before using the device, you must ensure it is properly configured.
: The probe monitors the resulting change in voltage. Advanced internal signal processing translates this voltage variance into relative distance (cover depth) and bar size estimations. Step-by-Step Field Operation Workflow Connect the primary search probe directly to the
If your unit is not operating correctly, consult the manual for these common solutions: Potential Cause Probe not connected or damaged. Check cable connections and probe condition. Inaccurate Cover Incorrect calibration. Recalibrate using the calibration block. High Interference Metal objects near the probe. Move magnetic objects (keys, watch) away. Drifting Reading Temperature change. Allow the probe to stabilize to the ambient temperature. Conclusion Proceq Profometer 4
Place a non-metallic spacer block of a known thickness (e.g., exactly 20 mm) between the concrete surface and the probe. Take a second reading ( C2cap C sub 2 ) directly over the same rebar. Compare the difference between C1cap C sub 1 C2cap C sub 2
Before conducting any on-site measurements, the instrument must be zeroed far away from any metallic interference.
Official manuals for the legacy Proceq Profometer 4 are no longer hosted directly on the main Proceq/Screening Eagle product pages, which now prioritize modern series like the PM8000, PM8500, or Profometer 6. Humboldt Mfg. Co. Calibration (Zeroing the Instrument) are now available, many
