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.
Move the probe slowly across the concrete surface. The signal strength will increase as you approach a bar.
Used to map a grid of reinforcement over a larger rectangular area, producing a "heat map" of cover depths. 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
Before beginning any investigation, ensure you are not wearing metal jewelry or watches, as these can interfere with the magnetic field. Hold the probe in the air, away from
The center line of the probe indicates the precise location of the rebar. 2. Essential Operating Steps
When the visual indicator (rifle scope or LED) is centered, the probe is directly over the rebar. The signal strength will increase as you approach a bar
The is a classic eddy current pulse induction instrument designed for the non-destructive location of reinforcing bars (rebar) and the measurement of concrete cover depth. While succeeded by advanced digital units like the Profometer PM-8000 or PM-600 , the Profometer 4 remains a staple for on-site quality control due to its reliability. 1. Core Measurement Principles
