Press [NO] to abandon any changes made and reset the metal detector product
settings back to their original values. Press [YES] to keep any changes and continue
operating with these settings. If the operator level pass code was entered when the
ADC screen was selected, then this confirmation message will not appear
9.1.1 Graphics menu functions (ZRCFBP)
The graphics menu can be displayed by pressing the menu toggle key. The graphics
letter menu is shown as ‘ZRCFBP’ and its functions are described as follows:
9.1.1.1 Zoom display (Z) :
The display is magnified by pressing [+] to increase the scale, or condensed by
pressing [-] to decrease the scale. Each time this is done the detection envelope and
previous signal trace is redrawn at the new size. Note that not every point on the
previous plot may be re-drawn. A single press will result in a step of one scale
interval. Continual presses will cause increasingly larger steps.
9.1.1.2 Rotate detection envelope (R) :
The phase angle will be increased by pressing [+] or decreased by pressing [-]. Each
press will cause a step of 10
°
. This option is meant for a fast but crude positioning of
the detection envelope, but for a precise amendment of the phase angle the Edit
menu should be used instead, described below in the ‘Phase Adjustment (P)’
section.
9.1.1.3 Clear display (C) :
Pressing either [ ] or [ ] will wipe all plotted signal from the ADC display.
9.1.1.4 Flash mode (F) :
The flash signal plotting mode can be turned on by pressing [ ] or turned off by
pressing [ ]. The default mode is ‘off’ which continually draws the ADC trace over the
top of any previous plot and so allows an historical picture to build up indefinitely. By
turning on the ADC flash plotting mode, the display will be continually cleared after
each product passes, displaying the last product signal briefly before returning to a
clear display.
9.1.1.5 Bar graph display (B) :
