When the visual indicator (rifle scope or LED) is centered, the probe is directly over the rebar.

Ideal for long-distance measurements across a single layer of rebars. proceq profometer 4 manual
If you "chase" the signal up and down and it remains consistent, you are following the length of the rebar. 3. Advanced Measuring Modes
Accuracy in cover measurement depends on the input bar diameter. If the diameter is unknown, the device can provide an estimation once positioned directly over the bar. When the visual indicator (rifle scope or LED)
Move the probe slowly across the concrete surface. The signal strength will increase as you approach a bar.
Before beginning any investigation, ensure you are not wearing metal jewelry or watches, as these can interfere with the magnetic field. Move the probe slowly across the concrete surface
While the basic "Spot" mode is standard, the Profometer line supports specialized scans:
Hold the probe in the air, away from any metal objects, and press the Zero button. This calibrates the device to the current environmental conditions.
The Profometer 4 operates on the . A coil in the probe is energized by a current pulse, creating a magnetic field. When this field encounters a metallic object like a rebar, it induces eddy currents, which in turn generate a secondary magnetic field. Precision: It typically offers an accuracy of
