1.5 Requirements on the Operating Personnel

The instrument should be operated only by staff trained for this purpose!

In addition, basic knowledge of metrology according to DIN 1319 is essential for performing correct ferrite content measurements and evaluations.

Basic computer knowledge regarding configuration, operation and programing as well as knowledge of the software in use, which may be obtained from respective instruction manuals, is required when using the instrument in conjunction with a computer.

Page 10 Operators Manual FERITSCOPE® FMP30

1.6 Power Connection

To avoid damage to the instrument or wrong measurement results due to a wrong line voltage, the instruments must be connected to a power outlet only via the AC adapter provided by Helmut Fischer GmbH Institute for Electronics and Metrology. The line voltage must agree with the line voltage rating stated on the nameplate of the AC adapter.

1.7 Environmental Conditions

EMC

The instrument complies with the laws concerning electromagnetic compatibility of instruments (2004/108/EC). The measured values are not influenced by the highest level of interference mentioned in the EN 61000-6-2 Standard (which references the Standards EN 61000-4-2, EN 61000-4-3 and EN 61000-4-4). In particular, the instrument is shielded effectively from strong electromagnetic fields (e.g., motors, power lines, radio transmission towers).

Low Voltage

The instrument adheres to the Low Voltage Directive 2006/95/EC.

Ambient Temperature Range During Operation: +10°C ...+40°C

Important Information

Temperature Range During Storage and Transport: +5°C ... +60°C

Temperature behind glass panes (e.g., in cars) in direct sunlight easily rise above 60°C! To avoid damage from heat, do not store the instrument or accessories in such places.

The instrument and accessories (in particular the AC adapter) must not come in direct contact with water! Risk of electrical shorts! Instruments or accessories may be operated, kept or stored only in places, where the relative humidity is between 30% and 90% (non-condensing).

Operators Manual FERITSCOPE® FMP30 Page 11

Because the instrument and accessories are not acid resistant, avoid direct contact with acid or acidic liquids.

The instrument and accessories are not suited for operation in explosion-hazard areas!

Protect the instrument and accessories from static charges! Electrical discharges may damage internal components or

Important Information

delete internal memories.

1.8 Probe Handling

To avoid breakage of the wiring, do not bend the probe connector cable! The radius of rolled up probe connector cables should always be at least 50 mm!

Probeconnector cable

R ≥ 50 mm !

Fig. 1-1 Probe handling

During the measurement, the magnetic poles of the probes are placed directly onto the specimen. Observe the following to keep wear of the magnetic poles during the contacting measurement to a minimum:

Place the probes speedily yet gently on the specimen surface! Avoid hard impacts!

Do not drag the probe across the specimen surface.

Page 12 Operators Manual FERITSCOPE® FMP30

Do not place standard probes on hot or acid-wetted surfaces; do not immerse them in liquids. Special probe models are available for such applications (ref. the probe data sheets of the brochure “Measurement Probes and Measurement Aids - Optimized Probes”). You can obtain this brochure from the Helmut Fischer GmbH Institute for Electronics and Metrology or from your authorized supplier.

1.9 Handling, Storage and Transport of the Base and the Calibration Standards

The instrument is normalized and calibrated using a base and calibration standards (ferrite standards).

Proper condition of the calibration standards is an important prerequisite for a correct calibration, and thus for a correct measurement.

Observe the following to ensure the proper condition of the calibration standards:

To keep wear of the base and the calibration standards during the contacting measurements to a minimum, use them for the calibration only and not for test measurements!

Do not soil or scratch calibration standards! Replace corroded or scratched calibration standards or those with strong indentations with non-damaged, clean standards.

Important Information

To protect the calibration standards from dirt or damage, keep them in their supplied case for transporting and storing.

2.3 Accessories

2.3.1 Probes

All probes that can be connected to the instrument are equipped with a memory chip, a so-called EEPROM, in their connector plug. Probe-specific information (such as probe type, production number, measurement method or coefficients of the master characteristic, for example) is stored permanently - even without power supply - in this memory chip, which can be overwritten as many times as desired. When powering up the instrument, this information is automatically retrieved and processed by the instrument; the instrument “recognizes” the connected probe. Correct measurements can be performed only if the probe that is assigned to the open Application is used for the measurement.

( Chapter 4.2 ‘Assigning a New Probe’, beginning on

Page 43).

Fig. 2-4 Probe plug of an FGAB 1.3-Fe probe

Various probe models are available for measurements on objects with different shapes and different surface properties. Special probes with different measurement ranges are available for the following areas of application, for example:

z particularly rough or abrasive surfaces z Particularly soft surfaces z damp, acidic contamination on the surface z particularly thick or thin coatings z hot surfaces z Coatings in pipes and bore holes

For available probe models and the probe model best suited for your application, see the respective probe data sheets of the brochure “Measurement Probes and Measurement Aids - Optimized Probes”. You can obtain this brochure from Helmut Fischer GmbH or from your authorized supplier.

Description of the Instrument

2.3.2 Base and Calibration Standards

A so-called base is used for the normalization; for the corrective calibration, one, two or three calibration standards (ferrite standards) are used in addition to the base.

Different calibration standard sets (corrective sets) are available for the corrective calibration of the instrument for the different measurement ranges. The calibration standard sets include:

z Base z 3 calibration standards with ferrite contents according to the desired mea-

surement range

A probe-specific calibration standard set for the master calibration (can be or-

Description of the Instrument

dered as an option) and a probe-specific calibration standard set for the corrective calibration (included with the probe) are available for each probe model and have been compiled specifically for this probe model.

You can obtain additional calibration standards on request from Helmut Fischer GmbH Institute for Electronics and Metrology or from your authorized supplier.

3.3.4 Switching Off the Instrument

Press the ON/OFF key switch the instrument off manually.

The instrument shuts down automatically if for about 5 minutes no measurements are made or no key is pressed.

3.4 Cleaning

To avoid damage to the instrument due to electrical shock, the line plug of the AC adapter must be pulled before cleaning the instrument or the accessories!

Soiled instruments or accessories should be cleaned using a plastic care product and a soft cloth.

The following should be observed during cleaning:

Risk of electrical shorts! Water or other liquids must not enter the instrument or the accessories! Do not immerse or place the instrument or accessories into liquids to loosen dirt through soaking! Do not pour liquids of the instrument or accessories!

System Setup, Maintenance and Cleaning

Wipe off dirt immediately to avoid it from drying onto the surface!

Do not use aggressive agents to clean the instrument or the accessories because they could attack the plastic housing!

To prevent damage, avoid scraping as a means of cleaning off dirt, in particular in the area of the probe tip.

Do not use aggressive agents to clean the calibration standards because they could damage the calibration standards! The use of damaged calibration standards (e.g., soiled or scratched standards) will lead to wrong

measurement results! (Additional information: 1.9 ‘Handling, Storage and Transport of the Base and the Calibration Standards’, beginning on

Page 13)

4 Probe Handling

4.1 Handling During Measurements

Probe Handling

z Always hold the probe at its grip sleeve (right fig-

ure).

z Always place the probe gently and at a right angle

on the specimen surface.

z Slide the grip sleeve to the specimen surface such

that the sleeve rests on the specimen (center and bottom Figure, right).

z With the default setting, a beep will signal the mea-

surement capture.

z Lift the probe off the specimen before making the

next measurement.

Avoid hard impacts. Do not allow the probe to hover directly above the surface. Doing so

will lead to erroneous readings. Do not bend the probe connector cable! Doing so can lead to broken

wires.

Example: Probe FGAB1.3

Grip sleeve

Specimen

Page 42 Operators Manual FERITSCOPE® FMP30

4.2 Assigning a New Probe

The instrument recognizes if the probe connected to the unit is different than the one expected according to the probe identification in the current Application. Reason: Each individual probe has a name that is comprised of the identification number and the model designation (e.g., FGAB 1.3F). The probe must be “registered” in the instrument under this name.

Potential Causes of the Problem:

z The probe received a different identification number after a repair.

z A newly purchased probe has not yet been assigned.

z If a user has more than one probe of the same probe model, a problem occurs

if a not yet assigned probe is connected to the instrument. In such a case, it is advisable to identify the probes and/or instruments with numbers.

If the measurements of an opened Application have not been made with the connected probe, [Ferrite] will flash on the display.

The corrective calibrations are deleted when the probe is assigned to one or more Applications; the user will have to perform a new cor-

rective calibration for each of these Applications (

5 Applications

All relevant settings and parameters for a measuring application as well as the captured measurement data are stored in a file - we refer to this file as an Application.

The instrument has the capability of setting up up to 100 different Applications. A maximum of 20,000 readings can be stored in these Applications. The measurements can be combined in up to 4,000 blocks.

Due to the magnetic induction measuring method, which captures all ferromagnetic components in the same manner, the measurements are always stated in ferrite. No distinction is made between the different material components, such as ferrite and martensite.

An Application consists of:

z Single readings, z Application-specific settings, and the z Coefficients that have been determined during the normalization and

corrective calibration (used for adapting the master characteristic stored in the probe plug to the current measuring application).

5.1 Setting Up an Application

Applications

A probe must be connected and an application must be set up before measurements can be made in an Application.

From the service function Measurement/Unit ( Page 184), specify the unit of measurement for measuring the ferrite contents of an

Application that is to be set up.

Once the linking mode is enabled (indicated by: on the LCD display), an automatic check will be carried out to see, whether one or more Applications have already been set up with the connected probe. If this is the case, no normalization is required when setting up the Application. Instead, the normalization and corrective calibration of the Application(s) that has/have been set up with this probe will be used.

5.2 Selecting the Desired Application

To make ferrite content measurements, a probe must be connected and an Application must be selected that has been set up using the connected probe before measurements can be made.

Applications

If [Ferrite] flashes on the LCD Display after instrument power-up or after selecting an Application, an Application has not yet been set up using the connected probe. It is not possible to make measurements when the display is flashing.

The following options exist if an Application has not yet been set up using the connected probe:

z Setting up a new Application using the connected probe ( 5.1 ‘Setting Up

an Application’, beginning on Page 45),

z Overwriting an existing Application using the connected probe

( 5.3 ‘Deleting an Application’, beginning on Page 49),

5.5 Assigning Application Designations

A customer-specific designation that can be comprised of a max. of 16 ASCII characters can be assigned to every Application. Assigning the Application designation can be carried out in the following manner:

z Use of the optional software MPNAME (the software is available from your

authorized supplier or directly from the Helmut Fischer GmbH Institute for Electronics and Metrology.)

z Transmitting the command “SAN” via the USB port ( 9.4.2 ‘Control

Commands’, beginning on Page 142) When making measurements in the matrix measuring mode, each block can be assigned a designation as well ( Page 115).

Once Application or block designations have been assigned, the designations appear in the information lines of the LCD display, where applicable, alternating with the respective numbers. On printouts, the Application or block designation will appear in place of the Application or block number.

5.7 Linking Applications

( 10.6.4 ‘Linking Applications’, beginning on Page 177) If the linking mode is enabled, all applications that have set up using the same probe (identified by the same serial number) will be linked with each other. Applications that have been linked to each use the same normalization and/or corrective calibration to determine measurements.

Example: If a separate Application has been set up for each batch of a component (using the same probe each time), it is useful to link the Applications to each other in order to compare the Applications to each other. Because these are the same kind of components, only from different batches, the same normalization and/or corrective calibration should be used every time.

5.7.1 Application Linking Procedure

Enable the instrument function “Linking mode” ( 10.6.4 ‘Linking Applications’, beginning on Page 177).

Perform a normalization to set up all Applications to be linked. The measurement probe is assigned to the Application ( 5.1 ‘Setting Up an

Application’, beginning on Page 45).

Applications

Perform a careful normalization or calibration on a typical uncoated component ( 6.2 ‘Normalization’, beginning on Page 68 and

6.3 ‘Corrective Calibration’, beginning on Page 71).

This as well as all subsequent normalizations or calibrations will be applied o all linked Applications; the normalization stored when setting up the respective Application will be overwritten.

Applications that have been set up with different probes of the same probe model (indicated by the same model designation but different serial numbers) will not be linked.

Operators Manual FERITSCOPE® FMP30 Page 63

5.7.2 Enabling and Disabling the Linking Mode

The linking mode is enabled or disabled from the Service functions of the instrument ( 10.6.4 ‘Linking Applications’, beginning on Page 177).

As long as the linking mode is enabled will appear on the

Applications

LCD display.

After disabling the linking mode, all Applications will again be independent of each other! Each Application can again be normalized and.or calibrated separately.

Immediately following the linking procedure:

Because a normalization or a corrective calibration has not yet been carried out immediately following the linking procedure, the normalizations and corrective calibrations of the linked Applications still differ from each other.

Applications

z Applications 4 and 6 are also linked to each other , because they

have been set up with the same FGABW1.3-FE probe (serial number 505).

z Even though Applications 1 and 3 have been set up with the same FGAB1.3-

FE probe (serial number 101), they are not linked to each other because the readings in Application 1 are displayed in ferrite percent [%] and the readings in Application 3 in ferrite numbers [FN].

z Application 5 is not linked to these two Applications because it has been set

up with the FGAB1.3-FE probe with the serial number 909.

z Application 2 is not linked to any other Application because no other Appli-

cation has been set up with the FGABI1.3_150FE probe (serial number 303).

After the corrective calibration of Application 6:

z Because Applications 4 and 6 are linked with each other, after the correc-

tive calibration of Application 6, the new corrective calibration (Norm 6n, Cal 6n, grayed out in Fig. 5-3) will be stored in Application 4 as well. The previous normalization and corrective calibration (Norm 4/6 and Cal 4/6) will be overwritten.

The normalization and corrective calibration of all other Applications remains unchanged in spite of linking, because a normalization or corrective calibration has not yet been carried out with these probes.

Page 66 Operators Manual FERITSCOPE® FMP30

6 Normalization, Calibration and Master

Calibration

The following factors influence the readings of a ferrite content measurement:

z Geometry of the specimen (size of the reference area, curvature, distance of

the measurement location from the edge of the specimen, sheet thickness, cladding thickness) The correction of these influencing quantities should be carried out based on the correction factors listed beginning on Page 116.

Creating user-specific calibration standards to determine, for example the influence of the curvature or thickness of the specimen is not recommended because the ferrite content of the starting material can be altered even with most careful mechanical processing, especially in the surface area that is registered by the probe.

z Probe tip wear

To a certain degree, probe tip wear can be corrected through a corrective calibration ( beginning on Page 71) or even better, through a master calibra-

tion beginning on Page 77). Too much probe tip wear, which becomes noticeable through an increased scatter of the readings on a specimen with a

homogeneous ferrite content distribution (e.g., a calibration standard), cannot be corrected. In such a case, the probe must be sent to your authorized distributor or directly to the Helmut Fischer GmbH Institute for Electronics and Metrology for repair.

Normalization, Calibration and Master Calibration

6.1 Information Regarding Normalization, Calibration and Master Calibration

z The information in Chapter ““1 ‘Important Information’, beginning on

Page 9“should be observed with every normalization, calibration and master calibration!

z All measurements should be performed with great care! Only in this manner

can the trueness specified for the used probe be ensured during the subsequent measurements.

Operators Manual FERITSCOPE® FMP30 Page 67

z Reference measurements should be performed after every normalization and

calibration to verify the normalization and calibration.

z It is not possible to start a normalization, corrective calibration or a master

calibration as long as the restricted operating mode is enabled (indicated by

on the LCD display) ( 10.6.1 ‘Restricted Operating Mode’, beginning

on Page 171)!

z A new block starts automatically after every normalization or calibration.

The measurements stored in the Applications will not be deleted after a normalization or calibration. If required, these measurements may need to be deleted prior to the next measurement.

z The normalization and corrective calibration affects only the open Applica-

tion. The other applications are not affected. The coefficients of the master characteristic stored in the EEPROM of the probe plug are also not affected.

However, if the linking mode is enabled ( on the LCD display), the normalization and the corrective calibration affect all Applications that are linked with the open Application.

z With external start enabled, a measurement acquisition can be triggered dur-

ing a normalization or calibration by:

- Pressing the FINAL-RES key,

- Transmitting one of the ASCII characters “G0”, “ES”, “EN” or

Normalization, Calibration and Master Calibration

6.3 Corrective Calibration

With a corrective calibration, a new zero point and one additional point (onepoint calibration with one calibration standard) or two additional points (twopoint calibration with two calibration standards) are established for the calibration curve of the open Application and are stored in the open Application. The coefficients of the master characteristic stored in the EEPROM of the probe plug are not affected.

z Suitable calibration standard set for the corrective calibration (in the desired

measurement range)

6.3.1 Selecting the Calibration Standards for the Corrective Calibra-

tion

Calibration standards are suitable for corrective calibrations only if their normalized countrates Xn are between the following Xn ranges:

z The normalized countrate Xn of the first calibration standard must be

between 0.02 and 0.9 (0.02 ≤ Xn calibration standard 1 ≤ 0.9).

z The normalized countrate of the second calibration standard (for a two-point

calibration) must be between 0.12 and 0.98 (0.12 < Xn calibration standard 2 ≤ 0.98).

z The difference of the normalized countrates of the two calibration standards

that are used for the two-point calibration must be greater than 0.1 (Xn calibration standard 2 - Xn calibration standard 1 = DXn > 0,1).

Determination of the countrate Xn: Page 85.

6.4 Master Calibration

The master calibration determines the coefficients of the master characteristic and stores them in the EEPROM of the probe plug. These coefficients determine the master characteristic, i.e., the correlation between the measurement signal of the probe and the ferrite content.

The EEPROM of the probe plug includes memories for the coefficients of two master calibrations. These two master calibrations differ in the following manner:

Factory master calibration

One master calibration (factory master calibration) is performed at the facility of the Helmut Fischer GmbH Institute for Electronics and Metrology with a very high precision using 5 calibration standards (incl. 1 base). It cannot be deleted or overwritten by the user.

User Master Calibration

You can set up the user master calibration by yourself using 5 calibration standards. This memory is empty when a new probe is supplied. Once the user has set up his “own” master calibration in the manner described below, he can overwrite or even deleted this calibration, if needed.

5 calibration standards are required to set up a user master calibration. They are part of the optional probe-specific master calibration standard set. The Xn values of one of these calibration standards must be within the prescribed Xn range of the master calibration for all 4 Xn ranges to be “occupied”.

Normalization, Calibration and Master Calibration

To increase the measuring precision in a certain measurement interval of the probe, up to 4 additional calibration standards with ferrite contents in this interval can be used. This means that max. 5 calibration standards can be in an Xn range of the user master calibration.

If the user master calibration is deleted and an new one is not set up, the factory master calibration will be used automatically to make measurements.

After setting up or deleting a user master calibration, all corrective calibrations that have been set up with the respective probe will be deleted. This means that after deleting the user master calibration and continued measurements using the factory master calibration, a new corrective calibration should be performed for each Application, if necessary.

Operators Manual FERITSCOPE® FMP30 Page 77

6.4.1 Selecting the Calibration Standards

For the user master calibration, the master calibration standard set available from the Helmut Fischer GmbH Institute for Electronics and Metrology as an option should be used! Only in this manner can the specified trueness be ensured during the subsequent measurements.

During the user master calibration, the master characteristic can be determined only if suitable calibration standards are used. If the master calibration standards of the Helmut Fischer GmbH Institute for Electronics and Metrology are not used, the normalized countrates Xn of the master calibration standards used in their place must be within the specific Xn ranges. The Xn values can be displayed after the 1st step of the user master calibration (normalization) ( 6.4.4 ‘Displaying Xn Ranges for Calibration Standards for the Master Calibration’, beginning on Page 83).

6.4.2 Performing a User Master Calibration

A user master calibration (hereafter simply referred to as a master calibration) must be performed only by experienced users.

Normalization, Calibration and Master Calibration

z The master calibration applies to all Applications that have been set up with

the same probe that has been used for the master calibration (because the coefficients have been stored in the probe plug of the EEPROM)! This applies to both an enabled and a disabled linking mode.

z After a master calibration is completed, the normalizations and corrective

calibrations of all Applications that have been set up with the same probe that has been used for the master calibration will be deleted automatically.

ics and Metrology or

Page 78 Operators Manual FERITSCOPE® FMP30

6.4.3 Master Calibration Procedure

The probe tip should be checked for potential wear prior to a master calibration.

Too much probe tip wear becomes noticeable through an increased scatter of the readings on a specimen with a homogeneous ferrite content distribution (e.g., a calibration standard).

In such a case, the probe must be sent to your authorized distributor or directly to the Helmut Fischer GmbH Institute for Electronics and Metrology for repair.

During the master calibration, the master characteristic can be determined only if suitable calibration standards are used.

The calibration standards are suited for the master calibration only if their normalized countrates Xn are within pre-established Xn ranges. The limits of the Xn ranges can be queried during the master calibration without affecting the calibration.

The master calibration is retrieved from the service function menu ( 10.9 ‘Performing a Master Calibration’, beginning on Page 187).

7.1 Preparing for a Measurement

The instrument and the measurement area must be prepared in the following manner before measurements can be made:

z Agreement on the reference areas (determination on where several single

readings are to be taken), according to DIN EN ISO 2064.

z Ensuring that the reference areas are free of interfering contaminants (e.g.,

moisture, dirt or grease) and are not damaged.

z Carrying Out the System Setup ( Page 29).

z Connecting a printer and if applicable switching it on (if a printer is available

and a printout is desired).

z Switching on the instrument ( Page 37).

Chapter 1 ‘Important Information’, beginning on Page 9

must be observed when making measurements!

z Selecting an Application that is suitable for the specimen ( beginning on

Page 45).

z Determining the instrument configuration ( beginning on Page 147).

z Determining the application-specific settings ( beginning on Page 52).

z Checking the normalization and calibration through measurements on cali-

bration standards.

Page 86 Operators Manual FERITSCOPE® FMP30

7.2 Parameters That Influence the Ferrite Content Mea-

surement

The following factors influence the readings of a ferrite content measurement:

z Specimen curvature

z Specimen thickness

z Cladding thickness

z Edge distance of the measurement location

The influence of the specimen's shape can be corrected by multiplying the measured ferrite contents with the respective correction factors ( beginning on Page 116).

Typically, a correction of these influences is necessary only if

z the curvature diameter of a convex curvature of the specimen is less than 50

mm, or

z the curvature diameter of a concave curvature of the specimen is less than 80

mm, or

z the thickness of the specimen is less than 2 mm, or

z the cladding thickness is less than 2 mm, or

z the distance of the measurement location from the edge is less than 2 mm.

Measuring

For very low ferrite contents, in particular the influence of the thickness should be determined specific to the measurement application.

7.3 Making a Measurement

To make a measurement, place the probe at a right angle on the specimen surface ( Page 42). The probe can be lifted off after the measurement acquisition, i.e., after the reading appears on the display. The instrument is ready to make measurements.

Operators Manual FERITSCOPE® FMP30 Page 87

Observe the following during the measurement:

z Measurements should be made within the reference area.

z To avoid erroneous readings, do not allow the probe to hover above the spec-

imen.

Measuring

z To obtain a correct air value, the distance to the specimen should be at least

25 mm.

z To allow sufficient time for a measurement accept, the time between individ-

ual measurements must be greater than 0.5 seconds.

7.3.1 Measurement Acquisition

As long as automatic measurement acquisition is enabled, measurement acquisition occurs automatically immediately after the probe is placed on the specimen. An audible signal will sound after the measurement acquisition (unless it has been disabled) ( 7.3.4 ‘Audible Signals After the Measurement Acquisition’, beginning on Page 93).

With the “free-running display mode on, measurement acquisition can be triggered in the following manner ( 7.6 ‘Measurements in the Free-Running Display Mode’, beginning on Page 104):

z Pressing the ENTER key

z Transmitting one of the ASCII characters “G0”, “ES”, “EN” or

z Transmitting the control character “ESC?” via the USB port (ESC =

ASCII27) ( 9.4.2 ‘Control Commands’, beginning on Page 142)

Regardless of how the measurement acquisition occurred, the reading will appear on the LCD display following the measurement acquisition.

Measuring

Operators Manual FERITSCOPE® FMP30 Page 89

7.3.2 Measurements With External Start Enabled

When an automatic measurement acquisition is not desired, e.g., when making measurements in pipes, boreholes or grooves, external start should be enabled and automatic measurement acquisition disabled (Enabling externally triggered

Measuring

measurement acquisition and disabling automatic measurement acquisition:

Page 180). Externally triggered measurement acquisition is recommended when the ferrite content is to be documented in a fixed, pre-specified lateral grid. In this manner, a measurement is registered even if the ferrite content is too low for an automatic measurement acquisition, i.e., when it is near or equal to zero.

With external start enabled, the measurement acquisition can be triggered manually in the following ways once the probe is positioned on the measurement location:

z Press the ∧ key

(not with a normalization or calibration)

z Press the FINAL-RES key

(only during a normalization or calibration)

z Transmitting the “ES” command via the USB port

( 9.4.2 ‘Control Commands’, beginning on Page 142)

With externally triggered measurement acquisition, the measurement acquisition can be delayed by up to 2.5 sec ( 10.7.3 ‘External Start’, beginning on Page 180)

7.3.3 Automatic Measurement Acquisition

A description of the two acquisition modes will follow under modes for automatic start of measurements after placing the probe). However, both methods will also work with externally triggered measurement acquisition ( Page 90), but not in the free-running-mode ( Page 104)!

Measurement Capture Through Area Measurements

With area measurements, the single readings are taken as fast as possible until the probe is lifted off. Only the determined mean value is stored.

Page 90 Operators Manual FERITSCOPE® FMP30

This measuring mode is advantageous if a mean values of the ferrite content distribution is to be determined quickly within a reference area. This mean value is added to a measurement series as a single reading. With online output of the single readings via the USB port enabled, only this mean value will be output as well.

The magnetic poles are subject to increased wear when moving the probe across a surface.

7.3.4 Audible Signals After the Measurement Acquisition

An audible signal will sound after the measurement acquisition (unless it has been disabled). The measurement acquisition signal indicates that a signal arriving from the probe has been recognized and that the probe can be lifted off the specimen.

In addition to measurement acquisition signal, the audible signals listed in the following Table may sound. Where applicable, the signals may sound in succession.

For example, if at a measurement with a fixed block size the last reading of a block has exceeded the upper specification limit, the measurement acquisition signal will sound followed by two short signals for exceeding the upper specification limit and one finally a long signal indicating the end of the block.

As an option, the measurement acquisition signal can be disabled ( 10.7.1 ‘Audible Signal’, beginning on Page 178). The other audible signals cannot be disabled!

After a measurement is taken that violates the upper

specification limit, appears in front of the reading on the LCD display. In addition, two brief audible signals sound after the measurement acquisition to indicate the violation of the tolerance limit.

If the measurement acquisition signal has been disabled, only the signal, or the signals, for violating the tolerance limits will sound. With outlier rejection enabled, the audible signals indicating an outlier measurement will sound when an outlier is recognized. In this case, the violation of the tolerance limit will not be indicated acoustically.

7.3.6 Measurements With a Fixed Block Size

When making measurements with a fixed block size,

z the block creation is carried out automatically after an adjustable number of

measurements has been performed by the instrument (Setting the Block Size: Page 57).
