Metal separation: Discriminator
In pulse system devices, the discrimination is given as the conductivity value. The
Goldstar GT18 values the type and volume of the metal. It is enough to give an
idea. No clear distinction is expected. However, the values given are generally
stable. When the metal is detected, it will give value and if it is close. Otherwise,
the value number is not displayed. Still detects metal. When the device achieves
full signal intensity, it will give numerical value. Conductivity value is between
0.99. We can divide these numerical values into 3 groups.
Numerical value table:
Between 00,35
Usually the number of coins and small metals.
Lead, bullets, aluminum, gold coins, thin gold bracelets, low weight silver
coins, copper bronze.
Between 00,35-00,75
Small large irons, Dense mineral, Bulk coins.
Bulk coins will usually value between 50.70. However, it should be interpreted
taking into account the sound separation. If the sound is full signal is not doubled
, it should be considered. If it gives a doubled sound, it will be iron even if it gives
this number range.
Between 00,75-00,99;
Silver or copper coins over 7 grams are included in this group.
In addition, bulky objects, bulky coins, Ingots, Aluminum, Brass, copper, bronze,
silver, gold items.
If the device gives value; Hold the coil on target several times to get a complete
idea. Generally, evaluate according to which number range. For example; You
tried it 4 times, gave 25 once, gave 40-50 3 times, then you should think that
there may be metal objects in the 35-75 number range. In short, you should
consider the range in which the numbers are moving rather than changing. For
the best accurate reading, the target type reading process should be repeated.
Thus, the same value should be read several times for that target.
