Chicago Electric 43150 operating instructions Before Getting Started

Before Getting Started

Before beginning an outside search, you must test the unit with samples of metal. Use the following:

•an iron nail

•a five-cent coin (nickel)

•a one-cent penny (zinc coin, after 1982)

•a silver quarter

Place the Metal Detector on a wooden or plastic table with the Search Coil face up. Make sure the table is away from TVs, computers, or any device that can cause interference. See Figure 4.

Figure 4

NOTE: Be sure to remove any watches, rings, or other metal objects on your fingers and hands.

Set Mode Switch to OPERATE and VOLUME dial to mid-point. The Metal Detector may sound a tone or be silent. If not already done, adjust the balance of the Metal Detector. (See the “NOTE” under “Functions And Indicators” on previous page.)

Once Detector is balanced, perform a test of a sample to adjust the controls to differentiate (“discriminate”) between ferrous (iron) metals and non-ferrous (metals.

1.To find ferrous metals (to

“discriminate” iron), set the DISCRIMINATION dial to MIN. See Figure 5.

Figure 5

2.Hold the iron nail sample close to the Search Coil. The indicator on the View Meter will swing to the left and the “hum, hum” tone will be lighter.

3.Bring the other coins close to the Search Coil. The indicator will swing to the right and the “hum, hum” sound will become louder.

4.To find non-ferrous metals (such as nickel), set DISCRIMINATION dial to midpoint setting. See Figure 6.
