Malvern Mastersizer Series User Manual

Á “Aux. Comms” connector
Auxiliary communications connector. Some sample preparation accessories (e.g.
Automated Sample Dispersion unit) are capable of controlling the optical unit.
When this is the case they are connected to this connector.
 “L.V. In” connector
Connector that carries the low voltage power supply into the receiver.
Features à to Æ are usually used when performing spray measurements.
à “Digital I/O” connector
The digital I/O connector is a general purpose user programmable I/O port. A
particular use for the port is to connect the spray synchroniser accessory.
Ä “Sweep trigger” connector
The sweep trigger is used to start a measurement “sweep” when using the spray
accessories.
Å “Exp. trigger” connector
The “Exp. trigger” is the “experiment trigger”. The experiment trigger is used to
start an experiment when using the spray accessories.
Æ “Abort” connector
The abort connector is used to stop the experiment triggered using the “Exp.
trigger” above.
Differences between the long and
standard bench Mastersizers
The long bench Mastersizer is able to measure a larger range of particle sizes. To
do this the long bench version has an extra sample area cover and an extra lens
(the 1000mm lens). When the 1000mm lens is used it is mounted in the
additional sample area. All other functions and features are the same as the
standard bench.
The following section gives an overview of the Malvern software.
