Page 3: About Your M-97
Research Laboratory manufactures a complete line of equipment for Line Tracing (Pipe and Cable Tracing). New to the M series is the ease with which the M-97 can be stored. Just compact the lower stem, twist the search coil 90 degrees, and fold the search coil flat. -
Page 4: Controls
On/Off Ground Rejection Control This control turns the M-97 on and off. It is used to electronically balance the M-97 to compensate for the natural mineral content of the soil or ground surface. When tuned properly, raising and lowering the search coil above the ground will not cause a change in the meter reading or audio tone. -
Page 5: Setting Up
Lower the coil close to the ground. There should be little or no change in the tone of the detector. If the M-97 changes tone when the coil is lowered to the ground, there is either a metallic object near the coil that is causing the instrument to respond, or the soil conditions are such that the M-97 needs to be more precisely balanced. -
Page 6: Searching
SEARCHING It is a good idea to establish a methodic search pattern. Avoid swinging the M-97 like a golf club, swing the detector side to side keeping the search coil the same distance above the ground. Your sweep pattern should be a slow, half-circle motion. If you are searching for a small target, it is a good idea to overlap your sweeps. -
