M-Scan to produce a different signal. When no ferromagnetic objects are present, the speaker emits a steady low frequency tone but as the M-Scan gets closer to a ferromagnetic object the audio pitch increases until the strongest signal from the object is directly under the end of the sensor tube. -

The battery compartment is located on the underside Take care to ensure that each battery is in the orientation shown of the M-Scan. Use a coin to rotate the latch anti clockwise on the holder (batteries should alternate) and that the holder 90°... -

(eg S2). Check that the battery symbol (on the top right of the display) shows at least two bars before commencing the search. The M-Scan will work with one segment showing but it is not recommended. -

Notes: Hold the M-Scan at 45° to the ground. Scan from side to side 1. Shielded cables (e.g. those in a steel conduit or armour) keeping the end of the sensor tube at the same distance from will not be indicated. -
Page 12: Application Note 1. Understanding The M-Scan Magnetometer
Application Note 1. Understanding the M-Scan Magnetometer The C-Scope M-Scan magnetometer is designed to detect the presence of iron and steel objects by sensing the magnetic field which surrounds them. The Earth’s magnetic field is ever present, and the instrument cancels this background field out, so that small variations in field can be detected. - Page 13 A representation of the Earth’s magnetic field is shown in Figure 1. Note that Magnetic North is a few degrees away The M-Scan has two sensors in the long metal tube, spaced from True North and that the Magnetic North Pole is actually approximately 20 inches/ 50cms apart.

Application Note 2. How Objects Appear to a Magnetometer Iron objects tend to concentrate the magnetic field lines around If the iron object is flat in shape and horizontal (A), it will appear them distorting the Earth’s field. The magnetic field produced by to be rather like a horizontal bar magnet, and will form a North an iron object will tend to follow the same orientation as the Pole on its North side and a South Pole of similar strength... - Page 15 North to South or vice versa. With careful use of the M-Scan, and knowledge of the pipe-section lengths, it may be possible to locate the flanged Figure 4 An iron pipe run may appear as a series of long joints.

Page 16: Application Note 3. Depth
It is recommended that the search is repeated at a lower sensitivity or with the M-Scan raised 0.5m (1.5 ft) so small objects close to the surface are not detected. -

Application Note 4. Using near Large Ferrous Objects A feature of the M-Scan is the ‘Erase’ button. The instrument Figure 6 A feature of the M-Scan is the ‘Erase’ button, is balanced during manufacture to produce a response close which cancels interfering fields from nearby objects to zero in Earth’s field. -

Note there is a null either side of the centre (B) where the lines of magnetic flux are at right angles to the sensor tube.
