Statement regarding improvements to 5100 Series Gaussmeters
The 5100 Series Gauss / Tesla Meters now have improved AC performance and several operational
improvements as a result of new DSP and microcontroller firmware.
Customers with meters manufactured prior to June 2007 and firmware versions below r2.00 and d2.00
should review this manual for changes in specifications. Certain operational sequences have been
made more intuitive and require fewer keystrokes. Refer to the appropriate section of the Operator’s
Manual for details.
Summary of changes:
• Auto Relative now toggles On/Off with just 2 keystrokes.
• Settings for "HOLD" and "Probe Zero" are no longer retained when powered on/off. This often lead to
the false appearance that the meter was malfunctioning in previous firmware versions.
• Analog Output now automatically applies optimum filtering to the signal, therefore the options of "LO"
and "HI" have been removed and it is simply an On/Off selection.
• Peak Hold has been greatly improved with a shorter acquisition time.
USB Hub Compatibility
Like many USB devices on the market such as printers and digital cameras, operation of the 5180
with a USB hub may be problematic. It is recommended that customers wishing to make use of the
remote operation capabilities of the 5180 make a direct connection to their computer USB port and not
use a hub. Operation with a hub is not recommended.

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

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 5170 / 5180 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 5180, and 2.000T (20.00 kG or 1592 kA/m) for the 5170. The instrument is capable of measuring static (DC) and alternating (AC)
magnetic fields.
The MODEL 5170 / 5180 consists of a palmsized meter and various detachable Hall probes. The meter operates on 4 standard
AA 1.5 volt alkaline batteries or can be operated with an external ACtoDC power supply. 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 a keypad.
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 (5180 only) 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.
(5180)
The meter, probes and accessories are protected when not in use by a sturdy carrying case.

Press the POWER switch. There will be a momentary audible beep and all display segments will appear on the display.
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 halt if there is no probe connected. Until the probe is connected the phrase
“Err” will appear accompanied by a flashing “PROBE” annunciator as shown in Figure 3-7.
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.

LOW BATTERY CONDITION
The meter is designed to use four standard AA 1.5V alkaline batteries . When the battery
voltage becomes too low the battery symbol on the display will flash, as shown in Figure 3-8.
Replace the batteries or use an external AC to DC power supply.
Instrument specifications are not guaranteed when a low battery condition exists!
OVERRANGE CONDITION
If the magnitude of the magnetic flux density exceeds the limit of the selected range the meter
will display a flashing value of “2999” (gauss or tesla mode) or “2387” (ampere meter mode).
The next highest range should be selected. If already on the highest range then the flux
density is too great to be measured with this instrument.
AC OR DC MEASUREMENT SELECTION
The meter is capable of measuring either static (DC) or alternating (AC) magnetic fields. To
choose the desired mode Press the SHIFT pushbutton followed by the right (4) arrow to select
AC or DC on the display. The DC and AC mode is discussed in more detail later in this
section. This setting is saved and will be restored the next time the meter is turned on.
UNITS OF MEASUREMENT SELECTION
The meter is capable of providing flux density measurements in terms of gauss (G), tesla (T)
or ampere/meters (A/m). To choose the desired units, Press the SHIFT pushbutton followed
by the left (3) arrow pushbutton. Press the up (5) and down (6) arrow pushbuttons to select G,
T or Am on the display. This setting is saved and will be restored the next time the meter is
turned on.
