2 Safety
This section introduces the safety concept of the instrument and contains general rules of behavior
and warnings from direct and indirect hazards concerning the use of the product.
For the users safety, all safety instructions and safety messages in the individual sections shall
be strictly observed and followed. Therefore, the manual must always be available to all persons
performing any tasks described herein.
2 .1 User qualification
The instrument may only be used by laboratory personnel and other persons who on account of
training and professional experience know the potential dangers that can develop when operating the
instrument.
Untrained personnel, or persons who are currently being trained, require careful supervision by a
qualified person. This Operation Manual serves as a basis for training.
2 .2 Proper use
The NIRFlex N-500 has been designed and built as a rugged analysis instrument. It serves to deter-
mine the matter and concentration of substances in samples above its measuring tolerance limit (no
trace analysis). Thanks to its ruggedness, the instrument is suitable for use on most production floors
(at-line, near-line). For suitable environmental conditions see tables of technical data.
The NIRFlex N-500 system can be applied for the following tasks:
Qualitative analysis
Differentiation of chemically different substances (e.g. raw material testing of incoming goods); •
Differentiation of chemically similar substances or substance grades. •
Quantitative analysis
Determination of quantifiable product properties such as concentrations or physical parameters •
(viscosity, particle size).
2 .3 Improper use
Any other use than the one stated above and any application that does not comply with the technical
data is considered to be improper use. Improper use can cause hazardous situations for the operator
and / or for the instrument and might cause consequential property damage.
The operator bears the sole risk for any damages or hazards caused by improper use!
In particular, the following uses shall not be permitted
Installation and use in environments where explosion protection is required •
User repair and maintenance work other than described in this manual •
Reuse of sample material for production that has been in direct contact with non-food safe mate- •
rials and surfaces
