Introduction
UNDERSTANDING FLUX DENSITY
Magnetic fields surrounding permanent magnets or electrical conductors can be visualized as a collection of magnetic flux lines, lines of
force existing in the material that is being subjected to a magnetizing influence. Unlike light, which travels away from its source
indefinitely, magnetic flux lines must eventually return to the source. Thus, all magnetic sources are said to have two poles. Flux lines are
said to emanate from the “north” pole and return to the “south” pole, as depicted in Figure 1-1.
One line of flux in the CGS measurement system is called a maxwell (M), but the weber (W), which is 108 lines, is more commonly used.
Flux density, also called magnetic induction, is the number of flux lines passing through a given area. It is commonly assigned the symbol
“B” in scientific documents. In the CGS system, a gauss (G) is one line of flux passing through a 1 cm area. The more commonly used
term is the tesla (T), which is 10,000 lines per cm. Thus,
1 tesla = 10,000 gauss
1 gauss = 0.0001 tesla
Magnetic field strength is a measure of force produced by an electric current or a permanent magnet. It is the ability to induce a magnetic
field “B”. It is commonly assigned the symbol “H” in scientific documents. The unit of “H” in the CGS system is an oersted
(Oe), but the ampere/meter (Am) is more commonly used. The relationship is:
1 oersted = 79.6 ampere/meter
1 ampere/meter = 0.01256 oersted
It is important to know that magnetic field strength and magnetic flux density are not the same. Magnetic field strength deals with the
physical characteristics of magnetic materials, whereas flux density does not. The only time the two are considered equal is in free space
(air). Only in free space is the following relationship true:
1 G = 1 Oe = 0.0001 T = 79.6 Am

Section 1
Introduction
MEASUREMENT OF FLUX DENSITY
A device commonly used to measure flux density is the Hall generator. A Hall generator is a thin slice of a semiconductor material to which
four leads are attached at the midpoint of each edge, as shown in Figure 1-2.
A constant current (Ic) is forced through the material. In a zero magnetic field, there is no voltage difference between the other two edges.
When flux lines pass through the material, the path of the current bends closer to one edge, creating a voltage difference known as the Hall
voltage (Vh). In an ideal Hall generator, there is a linear relationship between the number of flux lines passing through the material (flux
density) and the Hall voltage.
The Hall voltage is also a function of the direction in which the flux lines pass through the material, producing a positive voltage in one
direction and a negative voltage in the other. If the same number of flux lines pass through the material in either direction, the net result is zero
volts. This sensitivity to flux direction makes it possible to measure both static (dc) and alternating (ac) magnetic fields.
The Hall voltage is also a function of the angle at which the flux lines pass through the material. The greatest Hall voltage occurs when the flux
lines pass perpendicularly through the material. Otherwise, the output is related to the cosine of the difference between 90º and the actual
angle.
Figure 1-2
Hall Generator

The sensitive area of the Hall generator is generally defined as the largest circular area within the actual slice of the material. This active area
can range in size from 0.2 mm (0.008”) to 19 mm (0.75”) in diameter. Often the Hall generator assembly is too fragile to use by itself so it is
often mounted in a protective tube and terminated with a flexible cable and a connector. This assembly, known as a Hall probe, is generally
provided in two configurations:
In “transverse” probes, the Hall generator is mounted in a thin, flat stem, whereas in “axial” probes the Hall generator is mounted in a
cylindrical stem. The axis of sensitivity is the primary difference, as shown by “B” in Figure 1-3. Generally, transverse probes are used to make
measurements between two magnetic poles such as those in audio speakers, electric motors and imaging machines.
Axial probes are often used to measure the magnetic field along the axis of a coil, solenoid or traveling wave tube. Either probe can be used
where there are few physical space limitations, such as in geomagnetic or electromagnetic interference surveys.
Figure 1-3
Hall Probe Configurations
Handle the Hall probe with care. Do not bend the stem
or apply pressure to the probe tip as damage may
result. Use the protective cover when the probe is not
in use.

PRODUCT DESCRIPTION
The MODEL 5270 / 5280 GAUSS / TESLAMETER is a portable instrument that utilizes a Hall probe to measure magnetic flux density in terms
of gauss, tesla or ampere/meter. The measurement range is from 0.01 mT (0.1 G or 0.01 kA/m) to 3.000T (30.00 kG or 2388 kA/m) for the
5280, and 2.000T (20.00 kG or 1592 kA/m) for the 5270. The instrument is capable of measuring static (DC) and alternating (AC) magnetic
fields.
The MODEL 5270 / 5280 consists of a hand-held meter and various detachable Hall probes. The meter operates on one rechargeable 3.6 volt
lithium ion battery and can also be powered by an external supply through the USB C port. A retractable stand allows the meter to stand
upright on a flat surface. The large display is visible at considerable distances. The instrument is easily configured using the touchscreen.
Three measurement ranges can be selected or the meter can automatically select the best range based on the present flux density being
measured. A “zero” function allows the user to remove undesirable readings from nearby magnetic fields (including earth’s) or false readings
caused by initial electrical offsets in the probe and meter. Included is a “zero flux chamber” which allows the probe to be shielded from external
magnetic fields during this operation. Another feature called “relative mode” allows large flux readings to be suppressed so that small
variations within the larger field can be observed directly. Both the “zero” and “relative” adjustments can be made manually or automatically.
Other features include three “hold” modes, allowing either the arithmetic maximum, minimum or instantaneous peak values to be held
indefinitely until reset by the user. An analog signal is available from a standard BNC connector that is representative of the magnetic flux
density signal and is calibrated to 3 Volts full scale in dc mode or 3 VRMS in AC mode. This output can be connected to a voltmeter,
oscilloscope, recorder or external analog to digital converter.
The meter can be fully configured and flux density readings acquired from a remote computer or PLC using the USB communications port.
The meter, probes and accessories are protected when not in use by a sturdy carrying case.

Explosion Hazard - Batteries must only be changed in an area known to be non-hazardous.
Emergency first aid measures:
• In case or battery rupture or explosion, evacuate personnel from contaminated area and provide maximum ventilation to clear out fumes/gases
• In all cases, seek medical attention
• Eye Contacts: Flush with plenty of water (eyelids held open) for at 15 minutes
• Skin Contacts: Remove all contaminated clothing and flush affected areas with plenty of water and soap for at least 15 minutes
• Do not apply greases or ointments
• Ingestion: Dilute by giving plenty of water and get immediate medical attention
• Assure that the victim does not aspirate vomited material by se of potential drainage
• Assure that mucus does not obstruct the airway
• Do not give anything by mouth to an unconscious person
• Inhalation: Remove to fresh air and ventilate the contaminated area
• Give oxygen or artificial respiration if needed
Handling
• Use only approved chargers
• Never disassemble a battery or bypass any safety device
• Do not crush, pierce, short (+) and (-) battery terminals with conductive (i.e. metal) goods
Storing Lithium Batteries
• Do not store batteries above 60 °C or below -20°C
• Do not leave charging batteries unattended
• Store the battery in the original containers away from flammable materials
• Keep track of storage time
• Batteries should be stored at 10% - 50% capacity
• Do not store batteries longer than 10 years
• Do not store used batteries longer than 3 months before disposal
ATTENTION
Do not incinerate or dispose of lithium batteries in general trash collection. They may explode or rupture violently. Check state and local
regulations dealing with the disposal of these materials. You are legally responsible for hazards created while your battery is being disposed.

INSTRUMENT PREPARATION
1) Remove screen protector from the touch screen.
2) Plug in the USB cable into the meter.
3) Plug the other end of the USB cable into the power adapter and apply power to charge the battery fully (approximately 2 hours).
4) Install the probe by matching the keyway in the connector to that in the mating socket in the meter. The connector will lock in place when
fully installed. To disconnect, pull on the body of the connector, not the cable!
NOTE: In order to operate the meter with only the battery, USB power must be momentarily applied. After the battery power is
activated, this will not have to be repeated unless the battery is disconnected.

When battery power is used for the first time, momentarily apply USB power to the meter to activate the battery. This will need to be done any
time the battery is disconnected and re-installed.
Press the POWER switch. There will be a momentary audible beep (If audio is enabled).
The instrument will conduct a self test before measurements begin. If a problem is detected the phrase “Err” will appear on the display followed
by a 3 digit code. The circuitry that failed will be retested and the error code will appear after each failure. This process will continue indefinitely
or until the circuitry passes the test. A condition in which a circuit fails and then passes should not be ignored because it indicates an
intermittent problem that should be corrected.
If the self test is successful, the meter will perform a self calibration. During this phase, the meter will display a calibration sequence "CALX"
message. Calibration will not occur if there is no probe connected. Until the probe is connected the phrase “No probe connected” will appear in
the box where readings are normally displayed.
Per the SPECIFICATIONS section, allow 15 minutes warmup time for rated accuracy.
The most common errors displayed are a result of damage to the sensing element located in the tip of the probe. A damaged sensing element
can result in the following error codes: E064 and E067.
