1 INTRODUCTION

MULTISUS is purpose designed software for interfacing the MS2Susceptibility System with aWindows personal computer. It allows measurements on single samples and whole cores to berecorded and stored on file. The software is able to compensate for:

equipment drift;

container susceptibility; and

core diameter.

The software can also calculate:

volume and mass specific susceptibility; and

frequency dependent susceptibility.

Users may wish to compile the susceptibility data in other software, such as spreadsheets and

word processors, for further analysis and graphs. The MULTISUS for Windows data files areeasily imported directly into these.

As detailed in this Operation Manual, it is necessary to compensate for instrument drift during asequence of measurements if the optimum precision is to be obtained. This is accomplished bymaking an air measurement before and after each sample or series of measurements. Theinstrument drift is assumed to be linear during the measurement period and can be subtractedfrom the measured values. The software corrects the data after each measurement for singlesamples and at the end of a series of measurements for drill cores. Each measurement is timestamped to allow the correction to be applied.

It is particularly important to apply corrections before leaving the equipment for long periodsduring a sequence of measurements as the assumption that the drift is linear with time is only

valid over relatively short periods. For cores it is only possible to make an air measurement andapply the corrections at the end of the core measurement sequence.

The main section of this Operation Manual explains the different stages within the five sensoroptions in the MULTISUS for Windows software. These refer to:

MS2B Dual Frequency Sensor;

MS2C Core Logging Sensor;

MS2E Surface Scanning Sensor;

MS2G Single Frequency Sensor;

MS2H Down-hole Probe.

Further information is provided on printing susceptibility data from MULTISUS, saving data to disk

and opening and amending existing data files.

Reference should also be made to the 'Operation Manual for MS2Susceptibility System'.

MULTISUS 2.40 incorporates the following changes compared with version 2.31:

1 the MS2H sensor has been included;2 the ability to change number format such that numbers can be input/output on screen,

printed, written to files and read from files with commas as the decimal separator ifdesired.

8 EQUIPMENT DRIFT

The time taken for each series of measurements should be as short as possible. A smallequipment drift will occur during measurements due mainly to temperature changes. Whenmeasuring low values of susceptibility the drift may be significant and it is necessary to correctthe results to remove the effect. The measurement of air before and after each samplemeasurement or core sequence allows the estimated air value at the time of the samplemeasurement to be subtracted from the measured value. When measurements are mademanually the average of the air before and after the sample measurement is subtracted from themeasured value. The program uses a time stamp to correct the readings assuming a constantdrift rate between air measurements.

The MULTISUS software is supplied with a facility to check the drift of the system by takingcontinuous air measurements. This data may be useful in diagnosing whether there is excessiveequipment drift occurring or if there is significant interference from an external source.

On choosing Check Drift, you can select the type of sensor to undertake an automatic series ofreadings:

MS2B Dual Frequency Sensor;

MS2C Core Logging Sensor;

MS2ESurface Scanning Sensor;

MS2G Single Frequency Sensor.

MS2H Down-hole probe

You can add to measurement data, but not to equipment drift data. Clicking on the Start button forthe latter clears the existing drift data.

Make sure that the settings on the MS2meter are the same as those on the display screenbefore attempting to add data to an existing file.

The meter will be reset and zeroed before any additional data is added.


24/24



11 NUMBER FORMATYou can select whether MULTISUS uses a period or a comma as the decimal separator innumber formats. Different options allow you to choose the decimal separator used for screeninput/output, print output, file reading and file writing.

The default decimal separator is a period for screen input/output, print output, file reading and filewriting operations. To change the separator for any or all of these program features, selectChange Number Format from the menu. The change number format dialog will be displayed:

MULTISUS for Windows Change Number Format

Choose the desired decimal separator for each program feature and click OK. The settings will beremembered when you restart the application.

By selecting appropriate decimal separators for file reading and file writing, it is possible toconvert between number formats in existing MULTISUS files. For example, if you have anexisting file which uses the period decimal separator and want to open it, work with it and thensave it using the comma decimal separator, you would set screen input/output, print output andfile writing to use the comma decimal separator and file reading to use the period decimalseparator.

Be aware that if you use the wrong decimal separator when inputting a number of if you attempt

to read a file with the wrong decimal separator, the application will continue to function, but valueswill be truncated after the decimal separator.
