Operating Modes
Thickness Mode: Real‑time cover‑thickness reading, bar spacing display, JGJ‑mode multiple‑point averaging test.
Waveform Mode: Signal waveform output, suitable for dense rebar area to distinguish overlapping rebars.
Grid Mode: X‑axis & Y‑axis grid scanning to generate 2‑D rebar layout drawing.
Profile Mode: Section view to show depth position of each steel bar.
Calibration Mode: Air‑based calibration to eliminate environmental magnetic interference.
Data Management: Review historical data, transfer records to PC, clear stored files.
System Setting: Adjust auto‑shutdown time, set thickness correction factor, view device version & serial‑number.
Functions
1.Measure concrete protective‑layer (cover) thickness of steel bars.
2.Locate rebar position, trend and distribution inside concrete.
3.Estimate rebar diameter and measure spacing between adjacent rebars.
4.Multiple scanning modes: Thickness / Waveform / Grid / Profile / JGJ single‑point retest (full modes for ZD31).
5.Store, view, upload and delete massive test data.
6.On‑site air calibration; thickness error correction function.
7.Indicator light + buzzer alarm; prompt for mid‑point between two rebars for drilling and coring.
