INSTRUMENT OVERVIEW

Instrument overview

The SCINTREX SMARTMAG is an easy-to-use, light-weight, battery-powered,

portable magnetometer. It is a total-field instrument using the Larmor

frequency of precession of cesium atoms to measure the local magnet-

ic field. Optional upgrade kits allow the instrument to be used as a gra-

diometer or as a base-station.

Measured data is stored in memory along with the coordinates where

the measurement took place. In the advanced configuration modes,

you can also enter descriptive notes of up to 32 characters at any sta-

tion. The data can be displayed either numerically or graphically for

quick inspection of the data quality and spotting of anomalies. Data

can also be recalled from memory for visual inspection, dumped to the

serial port (RS-232) of a computer or directly to a printer. You can also

automatically correct your magnetic data for diurnal variations when

SMARTMAG CONSOLE BATTERY INSTALLATION/EXCHANGE

The SMARTMAG console is shipped without the battery installed. This is the proper procedure, while shipping and storing the instrument, to prevent deep discharge of the battery. Deep discharge can possibly cause permanent damage to the battery and will always shorten the battery life. This situation will occur because a small current is being drawn even if the instrument is turned off.

The following steps outline the battery installation:

1. Turn the instrument face down on a clean and even surface.

2. Unscrew both knurled screws on either side of the battery cover

and lift the cover off.

3. Place the battery into the recess in the rear panel of the

instrument.

4. Connect it carefully to the MAIN BATTERY connector. It is not

important which side of the plug is up, as long as the connector pins are properly aligned.

2-8

5. Replace the cover and tighten both knurled screws.

6. If this is the first time installation, proceed with battery charging.

The small size and low cost of the battery makes it convenient to carry an additional battery along as a spare.

You need not worry about a low battery causing data loss, since the

memory power requirements are much less than those needed to make

a valid reading of the magnetic field.

USING THE EXTERNAL BATTERY PACK

The standard battery should provide 24 hours operation at 20°C and 8

hours of operation at -40°C. Extended cold weather

may require more power than the standard battery together with a

spare can provide. To satisfy this additional requirement, the External

Heavy Duty Battery Pack (

provides about three times as much power as the standard battery. This

battery pack can be carried by the strap or attached to a belt.

To connect the external battery you must proceed as follows:

1. Turn the instrument face down on a clean and even surface.

2. Unscrew both knurled screws on either side of the battery cover.

3. Lift off the cover and store it somewhere convenient for future

use with the standard battery configuration.

USING AN EXTERNAL POWER SUPPLY

More demanding applications, such as an extended base-station oper-

ation, may require more power than can be provided with the either of

the

SCINTREX supplied battery packs. In this case you have two options:

a) AC-power

If a source of AC-power is available, the instrument can be run while the charger is connected to it. You will also be charging the standard internal battery, if it is installed, at the same time.

Note: Please be aware of possible magnetic noise from genera-

tors, and ensure that all cabling and sensors are as far away as possible from the generator as possible.

b) 12-volt battery (car or marine)

A 12-volt car battery may be more appropriate for other applications. The special External Power Cable ( 788 029) should be used for this purpose.

GUIDELINES

OPERATOR PREPARATION

Prior to conducting a search or survey with a cesium magnetometer,

the operator must remove all offending metallic items from his/her

body (some metals are non-magnetic or have low magnetic signature;

aluminum and brass for example). Commonly worn or carried magnet-

ic items include the following: belt buckles, watches, coins, steel toed

boots/shoes, metal buttons, pocket knives, compasses and magnets. It

may not always be obvious that an item contains metallic parts, for ex-

ample some shoes may have metallic eyelets. Of course, the

can be used to test suspect items.

Chapter

Guidelines

SMARTMAG

GEOMETRY OF DEAD ZONES

Cesium magnetometers will operate properly only if the angle that the

sensor head makes with the earth’s magnetic field vector is within the

ranges 10–85 degrees, 95–170 degrees, 190–265 degrees and 275–355

degrees. When the sensor head is parallel (more correctly in line,

which consists of parallel and antiparallel alignment) or at right angles

to the earth’s magnetic field vector, no usable signal is available. For a

small zone about parallel and right angle alignment there is still no us-

able signal. These zones are referred to as dead zones and are illustrated

in Figure 9 on page 3–2.

3-1

Guidelines

For parallel alignment we have two dead zones, the first about 0 degrees with range –10 to +10 degrees and the second about 180 degrees with range 170–190 degrees. These two zones are referred to as the po- lar dead zones and form two conical solid angles in three-dimensional space.

For right angle alignment, we have a dead zone whenever the sensor head is in the plane perpendicular to the earth’s magnetic field vector. This zone is encountered whenever the angle that the sensor head makes with the earth’s magnetic field vector is in the range of 85–95 (or 265–275) degrees. This zone may be considered as a disk in threedimensional space, and is referred to as the equatorial dead zone.

3-2

northern hemisphere.

Determining operating zones

DETERMINING OPERATING ZONES

1. To determine the operating zones of the SMARTMAG, face north

and swing the sensor head to the ground and then upwards. This will enable you to determine the angular range of operation by either the audio or display reading. When the sensor head is out of the operating range, the audio will vary wildy and the display reading will go out of range (range 20,000 to 99,999 nT). Preferably, the staff should be oriented so that it lies in the center of the angular range as just described.

2. While facing magnetic north, the range of sweep operation may

be determined by swinging the then to the right. The usable sweep angle will depend on your geographical position. If sweep operations are then conducted while walking in a northerly direction, the allowable sweep motion will be known by the previous test.

3. To determine the proper staff position and sweep angle for

walking south, perform the previous tests while facing south.

Guidelines

3-3

Guidelines

ADJUSTING THE SENSOR HEAD ANGLE

1. Adjust the angle of the sensor head relative to the staff by loosen-

ing the brass wing nut and then swiveling the head. The head should be positioned so that it is in the centre of the operating zone and that it does not enter a dead zone during a survey operation.

2. When the sensor head is in the appropriate position, tighten the

brass wing nut.

ASSEMBLING THE GRADIOMETER

The gradiometer option can be assembled either horizontally or verti-

cally. The gradiometer kit has six 0.5 metre inter-connecting poles.

Vertical Gradiometer

The vertical gradiometer is configured by using two 0.5 metre inter-

connecting poles to attain a vertical separation between the two sensor

staff assemblies, as shown in the diagram below:

Using the LED display and keypad

The SMARTMAG Model SM–4G

Horizontal Gradiometer

In the horizontal gradiometer assembly, there are two options. The gradiometer separation in the horizontal position can be 0.5, 1.0 or 1.5 metres. The separation is achieved by the number of inter-connecting polesused in the configuration. For example, if you require a 1.5 metre separation, all of the poles would be used. See the diagram below for a typical horizontal configuration.
