Page 25: Measurements
Manual measurements are only possibility for the MFK2-FB due to the absence of the Up/Down manipulator. It is also recommended to perform manual mea- surements when only bulk susceptibility is measured with the MFK2-FA. In this case it is necessary to Disable Up/Down manipulator in the Execute|Auxiliary Commands window. - Page 26 MFK2 – User Manual Operation basics Measurement routine is as follows: • Fill the information about the specimen in the appropriate window in the SAFYR7 software. • Press START button to execute the measuring routine. Empty coil (as the background measurement) will be measured for about four seconds. Do not disturb the instrument during the measurement.
- Page 27 Figure 6: 15-direction AMS measuring design for cubic samples Measurements with Up/Down Manipulator MFK2-FA is equipped with Up/Down manipulator which is necessary condition for the measurements with rotators and also brings enhanced comfort of measure- ments of the field variation of the bulk susceptibility. It can be used for single bulk susceptibility measurements as well.

Page 30: Calibration
MFK2 – User Manual Calibration 4.2 Calibration Calibration of the Kappabridge should be performed regularly (once per month at least) to achieve best possible results. Values of the calibration constants within re- quired range are good indicator of the proper function of the Kappabridge. Three different calibration routines are used - bulk calibration with manual holder, bulk and anisotropy calibration with classical rotator, and bulk and anisotropy calibra- tion with 3D rotator. -
Page 31: Calibration With Rotators
MFK2 – User Manual Holder Correction 4.2.2 Calibration with rotators Calibration with the rotator is more complex routine which measures three values - gain for bulk measurements (GainB), gain for anisotropy measurements (GainA) and Delta value which defines the coordinate system during the rotation of the specimen inside the measuring coil. -

MFK2 – User Manual Holder Correction 4.3.2 Holder Correction of the rotators After calibration with rotators perform the Holder Correction. After click on the Execute|Holder Correction in the Main menu (shortcut [F4]) Holder Correction window appears. Routine consists of three measurements of the bulk susceptibil- ity and and three measurements of the anisotropy of the empty rotator. -

Page 35: Maintenance
MFK2 – User Manual Maintenance 5.2 Maintenance 5.2.1 Cleaning the Holders and Rotator It is recommended to clean the specimen holders regularly, especially if you con- tinue with measurement of relatively weak specimens after measuring strong ones. For cleaning use pure water with a small amount of detergent and soft brush. Do not use alcohol for cleaning (it may cause damage due to heat of vaporization). - Page 36 MFK2 – User Manual Maintenance • Check the belt strain to set it later in the similar level and remember the belt mark position. • Release gently the ring, pay attention to the position and orientation of rubber washer, be careful not to lose it (see Fig. 10B). Remove the perspex ring. •...
- Page 37 MFK2 – User Manual Maintenance • Check once more the position of the black mark on the wheel and mount the belt on the shell. • Adjust the proper belt strain by picking-up slightly the part with motor and fixing the two screws (marked by the blue rectangle in Fig. 11A). •...

Page 38: Cleaning Of 3D Rotator
MFK2 – User Manual Maintenance 5.2.3 Cleaning of 3D Rotator The cleanliness of the rotator and its correct setting are basic conditions for the successful anisotropy measurements of the weak samples. Please keep your specimens as clean as possible. Any dust particles that fall from your specimens can increase friction in between 3D Rotator parts, so the volt- age for correct speed of rotator will increase. - Page 39 MFK2 – User Manual Maintenance • Unscrew two plastic screws marked by the blue circles on Fig. 13 and disman- tle the bottom part of rotator as seen on Fig. 15. Figure 13: Position of the screws on rotator Figure 14: A - Plastic ring and white rubber spacer, B - correct position of the spacer with respect to the plastic ring...
- Page 40 MFK2 – User Manual Maintenance Figure 15: Dismantled rotator • Clean all the parts with a piece of cloth (soft toothbrush) and warm water with little bit of detergent. Do not use any solvents, it may cause some serious damage to the 3D Rotator. Then clean all parts with clear water and dry them as good as possible.
- Page 41 MFK2 – User Manual Maintenance 3D Rotator assembling after cleaning • Insert the rotator shell (No. 2 on Fig. 15) into its holder (No. 1 on Fig. 15). Make sure that the marks shown on Fig. 16 A and B are simultaneously aligned as on the picture.
- Page 42 MFK2 – User Manual Maintenance • Connect rotator to the Kappabridge, switch on the MFK2 and run the initial- ization routine. • Open Auxiliary commands window (Execute|Auxiliary commands). Click on the INITIAL POSITION button, wait until this procedure is finished and check the position of the marks as shown on Fig.

Page 43: Cleaning Of Up/Down Mechanism
MFK2 – User Manual Maintenance 5.2.4 Cleaning of Up/Down Mechanism The Up/Down mechanism gets dirty after some time of use. Fig. 18 shows exam- ple of heavy contamination. It is heavily loaded especially during the high / low temperature measurement, when the number of up/down cycles is significantly greater than during the anisotropy measurement. - Page 44 MFK2 – User Manual Maintenance Figure 19: Cleaning of the Up/Down mechanism Cleaning procedure • See Fig. 19 for reference. • Open Auxiliary commands window (Execute|Auxiliary commands) and set the Up/Down Mechanism to down position using DOWN button. • After loosening the small screw (Fig. 19A) remove the arm of the holder. Please use the proper size of screwdriver to prevent damage of the screw.
- Page 45 MFK2 – User Manual Maintenance • Check Up/Down execution time DOWN buttons in Auxil- iary commands window (Execute|Auxiliary commands) of SAFYR7 program. Up time with installed rotator or furnace must be lower then 3.6 s. • Do not lubricate the inner cylinder by any lubricant. Do not use alcohol for cleaning (may cause damage of cylinder due to evaporation heat).
