  • Page 5: Section -1 Introduction

    Section 1 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.

  • Page 6: Measurement Of Flux Density

    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. Figure 1-2 Hall Generator A constant current (Ic) is forced through the material.

  • Page 7: Figure 1-3 Hall Probe Configurations

    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.

  • Page 8: Product Description

    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.

  • Page 15: Section - 3 Operating Instructions

    Section 3 Operating Instructions OPERATOR SAFETY Do not allow the probe to come in contact with any voltage source greater than 30 Vrms or 60 Vdc Do not connect the auxiliary power connector to an AC power source. Do not exceed 5 Vdc regulated. Do not reverse polarity.

  • Page 16: Operating Features

    OPERATING FEATURES Display. Liquid crystal display (LCD). Auto Zero. To select AUTO ZERO operation, press the ZERO pushbutton. Unit automatically returns to normal operation. Manual Zero. To select MANUAL ZERO operation, press the SHIFT pushbutton followed by the ZERO pushbutton. Use the LEFT (3) and RIGHT (4) arrow pushbuttons to select digit. Use the UP (5) and DOWN (6) arrow pushbuttons to make fine adjustments as needed.

  • Page 17: Instrument Preparation

    INSTRUMENT PREPARATION 1) With the power switch turned off apply pressure to the battery compartment cover at the point shown in Figure 3-4. Slide the cover open and remove. 2) Install four AA 1.5V alkaline batteries. The battery compartment is designed to indicate the battery polarity. Reinstall the battery compartment cover.

  • Page 18: Power-Up

    POWER-UP 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.

  • Page 19: Power-Up Settings

    POWER-UP SETTINGS The meter permanently saves certain aspects of the instrument’s setup and restores them the next time the meter is turned on. The conditions that are saved are: RANGE setting (including AUTO range) MODE (AC or DC) UNITS of measure (gauss, tesla or amperemeter) OUTPUT function Other aspects are not saved and default to these conditions: RELATIVE mode (turned OFF)

  • Page 20: Low Battery Condition

    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. Figure 3-8 Low Battery Indication Instrument specifications are not guaranteed when a low battery condition exists!

  • Page 21: Range Selection

    RANGE SELECTION The meter is capable of providing flux density measurements on one of three fixed ranges, or it can be programmed to automatically select the best range for the present flux density. The available ranges are listed in the SPECIFICATIONS section of this manual. The ranges advance in decade steps. The lowest range offers the best resolution while the highest range allows higher flux levels to be measured.

  • Page 22: Hold Mode Selection

    HOLD MODE SELECTION In some applications it may be desirable to hold a reading that is either greater than or less than all previous readings, or which has the greatest peak value whether positive or negative. The MAX HOLD function holds the reading that is arithmetically greater than all previous readings. For instance a reading of +125.0 is greater than +99.0 or -150.0.

  • Page 23: Min / Max Hold Usage

    If the reading exceeds the range limit the 5180 meter will hold a flashing value of “2999” (gauss or tesla mode), “2387” (ampere meter mode) or the maximum value allowed in the RELATIVE mode. The 5170 meter will hold a flashing value of "1999" (gauss or tesla mode), "1592"...

  • Page 24: Zero Function

    ZERO FUNCTION “Zeroing” the probe and meter is one of the most important steps to obtaining accurate dc flux density measurements. The ideal Hall generator produces zero output in the absence of a magnetic field, but actual devices are subject to variations in materials, construction and temperature.

  • Page 25: Automatic Zero Function

    AUTOMATIC ZERO FUNCTION The meter provides two methods to zero the probe. The first is completely automatic. Prepare the probe for zeroing, then press the ZERO pushbutton. The “ZERO” icon will flash and actual dc flux density readings will appear on the display.

  • Page 26: Manual Zero Function

    MANUAL ZERO FUNCTION The second zeroing method is a manual adjustment. This feature also allows the user to set the “zero” point to something other than zero, if desired. Position the probe for zeroing, then press the "SHIFT" pushbutton followed by the "ZERO" pushbutton. The “ZERO” icon will flash and actual DC flux density readings will appear on the display.

  • Page 27: Relative Mode

    RELATIVE MODE The RELATIVE mode allows a specific flux density value to be subtracted from all incoming readings. When the RELATIVE mode is active, all incoming readings are "relative" to an offset selected by the user. For example, if the displayed value is +100 gauss when RELATIVE mode is activated, and the flux density at the probe changes to +150 gauss the displayed value will be +50.0 gauss.

  • Page 28: Automatic Relative Mode

    AUTOMATIC RELATIVE MODE In the automatic relative mode, the present flux density as seen by the probe is used as the relative offset value. Prepare the probe and select an appropriate range and mode (AC or DC) as needed (AUTO RANGE is deactivated when RELATIVE MODE is used).

  • Page 29: Manual Relative Mode

    MANUAL RELATIVE MODE The second method by which to set a relative value is a manual adjustment. In some cases the user will wish to set an absolute relative value. To do this, insert the probe in the "zero flux chamber" provided with this meter. To manually assign a relative offset value, press the SHIFT key followed by the REL key.

  • Page 30: Analog Output Function

    ANALOG OUTPUT FUNCTION The 5180 meter is capable of providing an analog voltage signal proportional to the present flux density level. Calibration is set to 3.0V full scale DC or 3.0VRMS AC, depending upon the mode of operation. This signal, available at the BNC connector, can be connected to a voltmeter, oscilloscope, recorder, data logger, or external analog to digital converter.

  • Page 31: Analog Output Usage

    ANALOG OUTPUT USAGE See the SPECIFICATIONS section for frequency range and accuracy of the analog output. The analog output signal is calibrated to 3VDC or 3VRMS depending on the selected mode. The analog output voltage is proportional to the flux density being measured depending on the meters current range. For instance, when in the 30mT DC range a reading of 12.3mT relates to an analog output voltage of 1.23VDC.

  • Page 32: Figure 3-21 Adjusting The Dc Offset Of The Analog Output

    When both the ANALOG OUTPUT and AUTO RANGE features are active the following condition can occur. Suppose the present range is 3kG and the present reading is +2.8kG. The analog output will be +2.8VDC. The signal then increases to +3.2kG, which would force an automatic change to the 30kG range setting. The analog output will now be +0.32VDC because of the range change.

  • Page 33: Sources Of Measurement Errors

    SOURCES OF MEASUREMENT ERRORS When making flux density measurements there are several conditions that can introduce error: 1) Operating the meter while the LOW BATTERY symbol appears. Instrument specifications are not guaranteed when a low battery condition exists! 2) Failure to zero the error signals from the meter, probe, and nearby sources of magnetic interference. 3) Subjecting the probe to physical abuse.

  • Page 34: More Details On Ac Mode Operation

    6) Flux density can vary considerably across the pole face of a permanent magnet. This can be caused by internal physical flaws such as hairline cracks or bubbles, or an inconsistent mix of materials. Generally the sensitive area of a Hall generator is much smaller than the surface area of the magnet, so the flux density variations are very apparent.

  • Page 35: More Details On Dc Mode Operation

    An AC reading, being a true RMS value, has no polarity. However, when using the RELATIVE function in AC mode, a negative value may be displayed. A negative AC reading means that the present reading is less than the RELATIVE value. An unsigned value means the present reading is greater than or equal to the RELATIVE value. For example, if the original RELATIVE value was 100mT and the present field is 80mT, the result will be -20mT.

  • Page 36: Section - 4 Remote Operation

    Section 4 Remote Operation USB INTERFACE CONNECTION NOTE: Ensure that sleep mode is disabled prior to remote operation. Prior to using the remote operation capability of the meter, the USB driver software must be installed on a computer. This software was supplied on the User’s Manual CD for the meter, however newer software may be available. Please visit the F.W.

  • Page 37: Error Buffer

    ERROR BUFFER Errors are generated by a variety of sources, such as hardware errors or errors in the command syntax. If an error occurs a message is stored in an ERROR BUFFER. The message can be retrieved by a specific command discussed later in this section. STATUS REGISTERS There are four register sets that indicate the status of the instrument, such as errors or the present state of the meter.

  • Page 38: Information For Remote Operation

    Information for Remote Operation of 5180 Gaussmeter There are 2 DLL files which should be installed when you run the setup program from the 5180 User manual CD. They are libusb0.dll and usb5100.dll. They should have installed to your system when you ran the installation from the CD. Note: These files allow communication with the 5180 by higher level programming languages such as various types of C, C++ or C#, VisualBasic or development programs like LabView, Agilent VEE or TestPoint which can make calls to a DLL file.

  • Page 39: Other General 5180 File Information

    • Usb5100.DLL exports many functions that actually do the USB connection and communication with the 5180 meter. This is the DLL that provides the functions used by the Pacific Scientific OECO manufacturing test & calibration system. It calls functions that are exported by libusb0.dll. The functions in this DLL should be able to be called by most higher level programming languages using the methods described earlier in this document.

It also clears the error buffer. *ESE <NRf> – PROGRAM STANDARD EVENT ENABLE REGISTER A set bit in the STANDARD EVENT ENABLE register allows its corresponding event to set the ESB (event summary bit) in the STATUS BYTE register.

  • Page 47: Scpi Command Syntax

    SCPI COMMAND SYNTAX The SCPI commands go one step farther than IEEE488.2 and provide a language protocol and defines a standard set of commands to program most aspects of the instrument. These are the syntax rules: 1) The first character of any command string is a colon (:). 2) The commands are not case sensitive.

  • Page 50: Error Messages And Commands

    ERROR MESSAGES AND COMMANDS If an error occurs a message is placed in the error buffer. The message will contain a number, a comma (,) and a brief description of the error. Negative () numbers are used for SCPI defined messages while positive (+) numbers relate specifically to the meter.

  • Page 51: Status Commands

    STATUS COMMANDS The STATUS commands control and query the MEASUREMENT EVENT, OPERATION EVENT and QUESTIONABLE EVENT registers. :STATus:MEASurement:EVENt? :STATus:OPERation:EVENt? :STATus:QUEStionable:EVENt? Returns the contents of the specified EVENT register, then clears the register contents. :STATus:MEASurement:ENABle <NRf> :STATus:OPERation:ENABle <NRf> :STATus:QUEStionable:ENABle <NRf> Programs the specified EVENT ENABLE register with the value <NRf>. <NRf> is an ASCII string representing an integer mask. For instance a value of 45 decimal is the same as binary 00101101, thus setting bits 5, 3, 2 and 0 in the enable register.
