MAN 0382
Telephone socket specification
The telephone socket for remote support needs a direct Internet connection.
Computer specification
The Zetasizer software can run on a network but this is not recommended as, with
any software, running other software at the same time may affect the speed of the
Zetasizer software.
Contact the Malvern Helpdesk or website for the recommended computer
specification, otherwise consult the Software update notification document
supplied on the software CD.
Laser safety
Zetasizer Nano instruments are Class 1 laser products and as such, require no
special laser safety considerations during normal operation. However, during
servicing (which must be performed by a qualified Malvern representative), the
servicing engineer may be exposed to class 3b, or above, laser radiation. We
therefore recommend that the administrative controls recommendations of the
Laser Safety Regulations (IEC 60825-1(1993) +A1(1997)+A2(2001) are
implemented.
MPT-2 Autotitrator services
Nitrogen purge specification
Warning!
A Nitrogen supply must be used in a well ventilated environment.
The MPT-2 Autotitrator has a purge connector for connection of a Nitrogen purge
supply. This can be used to blanket the area directly above the sample and prevent
any absorption of Oxygen that may change the pH characteristics of the sample, i.e.
cause a pH drift.
If a Nitrogen supply is required it must conform to these specifications:
The Nitrogen supply must be dry, free from oil and filtered to remove any
contaminants that could affect the sample.
The flow rate should be adjustable between 2 and 20 ml/min.
