1. Introduction
1.1. Important Information
1.1.1. Declaration of Conformity
All lexsyg equipment from Freiberg Instruments is conform to the European legal provision
about the electromagnetic compatibility (89/336/EWG), the directive of the modification of CE
marking (93/68/EWG), the EG machine directive (2006/42/EG) and the EG low tension
directive (73/23/EWG).
The CE sign is arranged on the specification plate. Please attend on the obligatory national
and local regulations!
Through a non-coordinated modification of the equipment this declaration loses its validity.
1.1.2. Target Audience
The manual is written for the operating personal of the lexsyg(luminexcence excitation
system for geological and archaeological applications).
The operators should have the essential professional competence for all work with the
equipment.
The personal is obliged to read and completely understand the manual.
The documentation ought to be placed in reach of the equipment.
1.1.3. Intended Application
• The handler is in charge to only use the lexsyg equipment in the descript manner.
• The handling of the measuring equipment is only allowed subjected to the conditions
named:
–in this manual
–on the specification plate
–in the technical specification corresponding to the respective brief.

• The lexsyg equipment is used for luminescence measurements either by thermal (TL),
optical (OSL) or radiation (RF) stimulation. It is configured for the measurement of certain
materials.
1.1.4. Not intended Application
All applications notwithstanding the technical data on the specification plate or the terms
named in the contract of delivery and the usage with missing or damaged safety installations
is prohibited.
1.1.5. Safety Installations
The following arrangements serve the security of the operating personal:
• electrical access with grounding conductor and safety plug
• laser protection service
• mechanical safety doors with safety key
• electronic safety precautions
• software safety routines
• for radiation safety precautions see attachment one
Without any of these installations a usage of the equipment is forbidden.
1.1.6. Impact of the Warning Notices
Observe the warning notices! They are distinguished:

1.2. Fundamental Advices
1.2.1. Preface
It’s necessary to consider the warning notices. The defiance can lead to damage of healthy
and property.
Service and repairing of the equipment is only allowed to skilled personal.
The removal of the whole equipment or single parts should be carried out by consideration of
the local legal regulations.
1.2.2. Security Warnings
1. Warning notice: Usage of LASER radiation! The radiation source is placed in the
lower department of the system. Don’t expose any body parts, e.g. eyes, arms, to the
radiation! This will lead to irreversible damages. All works at this partition of the
equipment should only be carried out by members of Freiberg Instruments.
2. Warning notice: Usage of alpha and beta radiation source! All legal precautions
have to be followed and special training as well as constant observation of operator
depending on the local regulations is required. For details see attachment one.
1.2.3. Commissioning and Operating Method
The equipment is constructed for luminescence measurements of mineral grains.
Transport:
Lexsyg systems are well prepared for transport. Open the cases carefully.
Warning: secure the system from tilting. It has a high balance point.
