calibration mode, while the user has about 4 seconds to spend
a few times a piece of ferrite over the coil. A small piece of
ferrite should be used, and do not bring it close to the sensor.
The angle of response from it will be calculated, but to save
this setting, you must click the OK button. When exiting “Esc”,
the setting is not remembered.
>> For RK instruments, the value is usually in the range from -
20 to -45. Also, after automatic calibration, I strongly
recommend manual calibration so that there is no response to
ferrite, the average size of a copper coin was about 80-81
according to VDI, a piece of foil 1.5x1.5 cm (not a lump) was
about 0 by VDI, and 5 kopecks of the USSR about 50 by VDI.
Remember - the correct ferrite setting is the key to the correct
operation of the device. Values need to be adjusted manually
+ \ - a few points, for example, auto-tuning set the value to -
30, save the settings, exit the operating mode, wave the
ferrite - there is a weak response, wave the copper coin, for
example, the value for VDI is +85, we return to the settings
and reduce the value to -29, save and exit to operating mode,
wave with ferrite - it is not voiced, the copper coin became
valid +83 by VDI, return to the ferrite calibration menu and set
the value to -28, save, exit, wave copper coin - the result is 80-
81, and then 5 kopecks of the USSR, foil, etc., in general,
ferrite calibration is a matter of experience, if the ferrite is not
set correctly, the device may not see large copper targets at a
depth, giving false positives for strikes and show other
negative phenomena. Understanding this setting is the key to
a comfortable and productive search.
