Fig. 21
The cursor under a column specifies which sector is currently selected. On
the bottom right is displayed the VDI range for the currently selected group. The
column height corresponds to the volume level of the currently selected VDI
sector. A numerical value of the volume level is also displayed above the selected
VDI group. The choice of sector of adjustment is carried out by keys [
-
] and [
+
],
while adjusting the audio level is performed by using the and keys.
VOLUME of SERVICE SIGNALS [0... 10]
Sets the volume level of service signals
such as the pressing of keys, successful ground balance, the melody played upon
successful coil compensation etc.
KEYS SOUND [ON/OFF]
Enables or disables sounds made while pressing any
keys (buttons).
Border Fe - [-85 to +85]
Defines the VDI border for setting the iron tone. The user
may find this advantageous as the effects of ground minerals can affect the signal
from small non ferrous objects causing them to respond with a negative VDI number.
Thus the user may choose to set the Fe border to a specific negative value to include
these small low conductive targets. Also one may wish to include some small
desirable ferrous objects by adjusting the FE border to exclude these from the Fe
tone. While conversely one may wish to set this value to a slightly positive value
[+10] to include small annoying pieces of foil commonly found in modern sites littered
with trash. Setting is done on a personal preference of the user.
The NUMBER of TONES[1F, 2F, 3F, 10F, 91F]
Allows the user to set the number
of available tones .
VALUE 1F-
will generate a single tone on ALL targets including ferrous
targets. NOTE: a setting of 1F effectively negates the Border FE setting as
there is no separate FE tone
VALUE 2F-
A low tone will be generated for ferrous targets while a
high tone will be generated for all non ferrous targets. The border for
these tones can be set under BORDER FE option previously mentioned.
VALUE 3F
, A low tone will be generated for small ferrous objects
whose border has been determined by setting BORDER FE. A medium
tone will be generated for targets just above the Border FE setting but
below VDI +15. A High tone will be generated for targets within VDI +15
to +90 range.
