Proceq Profometer 4 Manual

Watch the indicator needle or digital display. The signal strength peaks (and the cover depth reading drops to its lowest value) when the probe is directly above the centerline of a rebar.

Remove all metal jewelry, watches, and rings before operating the device, as they can cause significant measurement errors. Upgrading to Modern Standards

Up to 120 mm (4.7 inches) depending on rebar diameter. proceq profometer 4 manual

: Identify bar orientation by moving the probe until you find the minimum cover reading. The probe should be parallel to the rebar for the most accurate depth measurement. Grid Scanning

allowed for the recording and statistical evaluation of large datasets. Basic Operational Steps According to standard operating procedures found in Proceq documentation , using the device typically involves the following: Calibration Watch the indicator needle or digital display

The Profometer 4 operates on the principle of electromagnetic induction. The search head contains a coil system driven by an alternating electrical current. The Eddy-Current Principle The coil generates a primary magnetic field.

The system functions by generating a localized magnetic field through the probe. When the probe passes over a rebar, the metal disrupts the magnetic field, inducing eddy currents. The Profometer 4 measures these disruptions to determine the proximity and characteristics of the reinforcement. The Effect of Rebar Size vs. Cover Depth Upgrading to Modern Standards Up to 120 mm (4

If rebars are closer together than the cover depth, their magnetic fields overlap. This causes the instrument to underestimate the true cover depth. Use a spot probe in these zones.

: To find the rebar's orientation, "chase" the signal. Move the probe up and down; if the reading remains constant, you are moving parallel to the bar.

tolerance window, use the internal calibration adjustment screw (located inside the battery compartment or on the side housing) to bring the needle back into alignment. 5. Advanced Testing Scenarios and Material Interference
