P U L S E 5
The electronic unit of the LORENZ PULSE 5 does
not suffer from any drift in general. That means
only in case of extreme temperature changes the
electronics have to be retuned with the zero-
control. The same should be done after very first
five minutes of operation since many components
inside the LORENZ PULSE 5 control box need to
warm up to their working temperature.
Ground signals which are mainly derived from
magnetic iron oxides will be indicated with an
increasing audio response when lowering the
searchcoil to the ground although no metal is
37
below the searchcoil. This kind of ground indication
can be simply eliminated by simultaneously holding
the searchcoil at constant height over the ground
and pressing the zero-push button for a second.
(see chapter 4, 5 for further details)
As long as the coil is hold at the same height during
searching there will be no loss in sensitivity after
having retuned the detector to the ground. When
expecting highly mineralized ground it is always
advisible to hold the searchcoil at a distance of at
least 10-30 cm from the ground depending on the
size of searchcoil connected.
The LP 5 is practically service free. The electronics control
box and the other components should always be kept
clean and dry. This is particularly important for the plugs
and sockets, which should never be stored when being
wet. The electronics control box is not waterproof and
should therefore not be exposed to rain or extreme
temperature changes. All searchcoils available for the
LP 5 are waterproof. When extension cables are in use
please make sure that the connectors are securely
fastened so that no water runs into the plugs.
All of the components can be cleaned from dust with
a soft cloth if necessary. In case of false signals or
any kind of unstable operation please check the
capacity of the battery first. Do switch off the LP 5
when the red battery light comes on. Disregarding
this can damage the built-in battery. Damages causes
by deep discharged batteries are not covered by
warranty!

temperature changes and humidity.
Different components like the front or rear panel,
circuit boards, battery, connectors can be easily
exchanged if necessary.
