Ã
Digital I/O connector
This connector is only used on the Mastersizer X or S. It is connected to the
digital I/O connector on the receiver unit of the Mastersizer S or X. It allows the
stirrer speed to be automatically read by the Malvern Software.
Ä
Mains voltage selector
This can be switched between 115/230V dependent on your local voltage
requirements. Select 115V for supply voltages 90 - 132V and 230V for supply
voltages 180 - 264V.
Å
Mains input connector
The mains power supply is connected to this connector.
Æ
Fuse
Accessory fuse holder, refer to the maintenance section for details on changing
the fuse.
The Malvern software
The Malvern software controls all the functions of the Mastersizer during a
measurement and then uses the collected data to calculate the result.
Qspec MS1 macro
As with most windows based software packages there is usually more than one
way to perform a task. Making a measurement using the Accessory is no
exception. It is possible to use the standard measurement interface described in
the “Getting Started Manual” to make a measurement. There is however an
alternative called the Qspec MS1 macro.
The Macro uses Standard Operating Procedures (SOP’s) to define and control a
measurement. These SOP’s are defined by the user. Using a SOP for a
measurement makes sure that each measurement you make is consistent.
Imagine, for example, you are in a quality control environment and you are
regularly measuring samples from a production line. It will be important to you to
make each measurement in a consistent way. You can use the Qspec MS1 macro
to define a measurement sequence, then each time you make a measurement
using that SOP the software will give you specific instructions e.g. “Add 50ml of
