• Signal – ON/OFF. When On averages graph signal over multiple search coil
passes.
• Scroll Rate – Adjust calibration and resolution of scrolling graph.
• Rule – ON/OFF. When On displays reference scale on bottom of scan graph.
• Title – ON/OFF. When ON, labels each frequency in use on graph.
• Pinpoint Meter – Select type of presentation to show on display for a target signal.
• Depth – ON/OFF. When ON, depth indication shown during pinpointing,
• Signal – ON/OFF. When ON, target signal strength shown during pinpointing.
• Fade Rate – Adjust rate the depth indication fades (resets) when the search coil
is no longer over a target.
• Rule – ON/OFF. When ON provides a gage for depth indication.
• Sizing – Select sizing display.
• VDI Confidence – ON/OFF. When ON a confidence rating is provided for VDI
target information.
• Depth – Display average depth over multiple search coil sweeps.
• Signal – Display target signal strength over multiple search coil sweeps.
• Rate – Adjust resolution of sizing graph. Preset at 2 “. Indicates that
the data shown from the left to right edge of the display was collected
within a time interval where the loop moved two inches.
• Rule – Display sizing gauge at bottom of sizing graph.
• Sweep Speed – Calibrates sizing reference at bottom of sizing graph for search
coil sweep speed.
• Title - ON/OFF. When ON, labels each frequency in use on graph.
• Mark Target – When ON, provides reference marks on sizing graph.
•
Spectragraph – Selects options for the block spectragraph during searching (toggle center position).
• Consistency – The rate an individual spectragraph bar builds height based on the
consistency (average) of the target signal after multiple search coil passes. By
adjusting consistency, spectragraph bars can build more quickly and narrowly or slower
and wider, based on the targets characteristics.
• Max – Higher numbers allow less target consistency for an individual
spectragraph bar to build height. Lower numbers require less consistency
to build height and have the effect of more readily indicating wider spectragraph
patterns.
• Intensity – In addition to the average target indication, Spectragraph bar also records the
intensity. Spectragraph height is based on the (average) of signals at that particular
VDI number as well as the intensity.
• Base Threshold – By adjusting the degree or %, Spectragraph can be adjusted
or calibrated to preference.
• Single Sweep – ON/OFF. When ON, spectragraph represents only the information from the last
sweep of the search coil. When OFF, spectragraph averages information over multiple sweeps
of the search coil. Averaging provides more accurate spectragraph information. However, in
clean ground with careful search coil sweeps, some may find signal sweep an effective.
• Fade – How quickly the spectragraph information automatically fades from the
display when Signal Sweep is on.
• Higher numbers fade (clears) the spectragraph more quickly. Lower numbers
slows fading. Select a fade rate that allows enough time to consider the information.
