of multi-band operation(MB=ON), select the desired value for the OS parameter.
3 Set “Autolearn=ON”. Exit from the programming phase and follow the display instructions.
4 Make the product pass several times through the metal detector, according to the value of the Transits
parameter (N.B.: in the case of loose product, the device automatically proceeds to analyse it correctly). N.B.: in
the case of model THS/3F, if MB=ON, carry out 3 x TN transits, with TN=2,3....
The message “Pass product” appears on the display, and the buzzer is activated (if enabled).
5 At the end of the transits the detector exits from the autolearn phase and the standard message appears on the
display.
6 Final operating check
6.1 Pass some pure product through the detector: the device should not set off any alarm.
6.1.1 Pass some of the product with a metallic sample: the detector should give an alarm. In such a
case, the procedure has been successfully concluded.
6.1.2 Otherwise, increase sensitivity and check that the bar-graph indication is not higher than 8 points
during the transit of uncontaminated product.
6.2 If the detector gives an alarm whenever some of the pure product passes through the probe, decrease the
“Sensitivity” parameter until the detector does not give an alarm (this is probably due to non-uniformity of
the product).
7 If a periodic test on the product is required, set the effective diameter of the metal mass used in the relevant
parameter in the MD Test menu: parameter FD if the sample is of ferromagnetic metal, parameter SD if stainless
steel, or parameter ND if diamagnetic. In this way, the test report will show this value next to the result of the test
carried out.
N.B.: if the product can vary significantly in its electromagnetic characteristics, adjust parameter SA (Sensitivity
Adjustment)
