Set your grid resolution parameters (e.g., lines spaced at 0.5m or 1.0m).

remains a legendary workhorse in the world of Non-Destructive Testing (NDT) . Known for its precision in rebar detection and cover measurement, it’s the tool engineers reach for when they need reliability without the fluff.

Press the button. The unit will perform a self-test. The display will show the software version briefly before entering measurement mode.

Use the spot probe; angle the scan diagonal to the upper mesh layer. Internal self-test failure or probe disconnection.

Are you trying to or fix a specific error code/symptom ?

To ensure longevity, the requires regular maintenance.

A: Yes, Appendix D covers the optional "Profometer 4 Wheel Probe" for rapid scanning. It requires recalibration of distance per revolution.

: Adjust the Zero Control Knob until the display reads zero (or the analog needle aligns perfectly with the baseline). Note: Perform this air-zeroing step periodically during long inspections to account for temperature drift. Step 2: Selecting Rebar Diameter

Always remove the batteries if storing the unit unused for more than two weeks to prevent chemical leakage.

Store the system inside its original padded protective transit case in a dry, temperature-controlled environment.

Place the probe directly over the center line of the marked rebar, aligning it parallel to the bar's direction.

Tie wires used to secure structural cages create localized metal clusters. These clusters distort the primary magnetic field, leading to erratic needle behavior or unexpected spikes. Operators should take readings away from known intersection joints whenever possible. 4. Aggregate Materials and Additives

Replace batteries; allow the unit to acclimate to site temperature, then re-zero in the air. Fluctuating or erratic readings Nearby electromagnetic interference (EMI) or loose cable
