Eddy current induction with compensated magnetic fields.
Always store the unit in its original foam-lined case to protect the sensitive search head from impact. Need the Original PDF?
The final chapters of the manual deal with longevity. Here are critical excerpts:
: Before starting, the device must be "zeroed" or balanced by holding it away from any metallic objects and pressing the reset or zero button.
Operating the Profometer 4 effectively requires proper probe selection and methodical scanning techniques. Selecting the Right Probe proceq profometer 4 manual
Eddy-current bar locators are highly sensitive to external variables. Operators must account for the following factors in the field:
The concrete deck in front of her looked solid. But the client’s survey had shown shadows—anomalies in the rebar network two inches below the surface. If the rebar spacing was off by more than a centimeter, the entire span would fail the load test. And failure meant firing squad of investors.
Find an area where the target rebar is isolated from parallel or perpendicular bars.
Remove loose debris, moisture, or magnetic dust from the concrete testing area. Eddy current induction with compensated magnetic fields
Always remove the AA batteries before storing the device for more than two weeks to prevent acid leaks.
The Profometer 4 is powered by a rechargeable battery. To install it:
: For larger areas, use a fixed grid pattern. This makes data visualization in your report much clearer for clients to understand. 3. Comparison with Modern Reporting
Proper maintenance ensures instrument longevity and prevents costly field failures. The final chapters of the manual deal with longevity

The official manual mandates a full factory calibration every 12 months. However, the built-in "Air Calibration" should be done at the start of every workday.
Clear the immediate workspace of extraneous metallic objects. Zero the instrument in the air as outlined in Step 3.1.
Once the bar is centered, press the "Measure" button on the probe handle. The screen shows:
