During operation it is always possible to change
the settings of the Z2. Above the function icons
which will be shown all the time there is an intensi-
ty bar graph, another +/- GPS direction nder and
dierential bar graph indicator which will come on
when dierential coils are connected, data logger
icons, battery indicator, a FErrous/ NON- FErrous
icon (works with double D coil only) and a conduc-
tivity number in order to display the time duration
of the eddy currents produced in a detected metal
object.
000-099 CONDUCTIVITY /
TIME DELAY READING
The number for the conductivity/ time delay mea-
surement is static and will come on when certain in-
tensity is reached and stays on as long as the coil is
over the metal. A time delay reading which is main-
ly derived from the conductivity, permeability and
the objects size is displayed with a specic number
on the LC Display. Any metal object detected will
give a specic number (000 to 099). Therefore, a
certain intensity of the metal signal is necessary for
a time delay reading. The number simply appears
when a reading was possible. The indication will be
stored as long as the search coil is over the metal
and turns o when the search coil passes the same.
Possible indications without guarantee:
000-035 low conductivity
like small coins nuggets, foils
040-060 medium conductivity
like ferrous metal objects
065-099 high conductivity
like large non- ferrous metal objects made of
copper, brass, silver for example
FERROUS / NON-FERROUS ICONS
This function does only work with the 26 cm or 35
cm double D- coils. Ferrous metal objects like iron
for example produce a FE indication at the top of
the display and Non-ferrous metal objects like gold
silver or copper or large ferrous objects will result
in a NON- FE icon indication when the search coil
is over the metal. The two icons will turn o if no
