1.To adjust the settings to PREVENT the unit from detecting iron metals, set the VOLUME and SENS dials at midpoint.
2.Then set MODE switch to DISC and the DISC/TONE dial to about “9 o’clock.” See Figure 7.
Sweep the nickel in front of the Search Coil; the unit will not respond to the nickel or to the iron nail. But it will respond the other samples.
5.To prevent the zinc penny from being detected, set the DISC/TONE dial to about “1 o’clock” See Figure 9.
Figure 9 Figure 7
3.As a test, sweep the iron nail sample 2 to 3 inches above the search coil. The unit will NOT respond (the meter pointer won’t swing and the unit is silent.) Sweeping the other samples should produce the “DI” tone and make the pointer move.
4.To have the unit differentiate nickel metals, set the DISC/TONE to about “11 o’clock.” See Figure 8.
Figure 8
By now, only the silver quarter should be detected.
NOTE: The discrimination position of aluminum is similar to silver. So both metals will be detected at the same time. The discrimination position of gold is similar to the nickel setting.
The Metal Detector can also be adjusted to detect all metals, yet signal a specific metal differently from the others.
6.Set the MODE switch to TONE and the VOLUME and SENS dials to their halfway points.
7.Set the DISC/TONE dial to about “9 o’clock” (the iron setting). Sweep the nail
