ments. However, the importance of sample preparation before measurement can-
not be overstated so we recommend reading the chapter on sample preparation
(Chapter 8 of the main User Manual) as a priority.
Within this manual, reference is made to the various people who will have access to
the dispersion unit. The following is a list of these people and their responsibilities:
Malvern personnel
Malvern personnel (service engineers, representatives, etc.) have full access to the
dispersion unit and are authorised to perform all service procedures that may
require the removal of the covers.
Supervisor
The supervisor is the person responsible for the management/safety of the disper-
sion unit and of its operation. The supervisor is responsible for the training of the
operators. The supervisor can perform all user maintenance routines identified in
Chapter 4 of the Essentials Manual.
Warning!
The supervisor/operator must never remove the covers of the instrument
or dispersion unit. Removal of the covers by unauthorised personnel will
invalidate the warranty of the dispersion unit.
Operator
An operator is a person trained in the use of the dispersion unit. The operator can
perform all user maintenance routines identified in Chapter 4 of the Essentials
Manual.
Warning!
Failure to follow this guideline could result in exposure to hazardous
voltages.
