Turn on the unit and check the battery status indicator.
Hold the probe in the air, away from any metal objects. Press the zero-balance button to calibrate the instrument to ambient electromagnetic conditions.
: Compare results against the design minimum cover to provide a clear "Accepted/Not Accepted" status. Section 5: Visual Documentation
Remove batteries if storing the device for more than two weeks to prevent corrosion damage.
Move the probe slowly in a straight line perpendicular to the suspected direction of the reinforcement bars. proceq profometer 4 manual
Once the bar is located, hold the probe directly over the center of the bar, oriented parallel to it.
Eddy current induction with magnetic field interaction.
Understanding the technical boundaries of the Profometer 4 ensures accurate field data collection.
This comprehensive guide serves as an operational manual, covering the core technical specifications, step-by-step operation, calibration procedures, and troubleshooting methods for the Profometer 4. 1. Technical Specifications and System Component Overview Turn on the unit and check the battery status indicator
Replace batteries; allow the probe to acclimate to the site temperature, then re-zero in the air. Incorrect rebar diameter setting.

When rebars are close together, their magnetic fields overlap, causing the instrument to read a shallower cover depth than actually exists.
The Profometer 4 utilizes electromagnetic pulse induction technology to detect ferromagnetic objects embedded in non-magnetic materials like concrete. Key Capabilities : Compare results against the design minimum cover
If you are looking to purchase a cover meter, I can compare the older Profometer 4 with newer models like the Profometer PM630 Go to product viewer dialog for this item.
Place a spacer of known thickness (e.g., 20 mm) between the probe and the concrete surface.
The Profometer 4 is designed for rugged field use. Unlike modern touchscreen devices, the P4 relies on a physical keypad and an LCD screen, making it highly durable in harsh site conditions.
A heavy-duty, shielded cable transmitting signals between the probe and the indicating unit.
Connect the probe cable to the socket on the display unit. Ensure the connector is screwed in or seated firmly to prevent signal interference during testing.
