1.3.- Safety warnings
This manual contains information and warnings about the
QNA-P/PV analyzer which must be followed to guarantee the proper
operation of all instrument functions and to maintain it in a safe
condition.
If the instrument is not used in accordance with manufacturer’s
specifications, the instrument’s protection may be damaged.
Where any protection failure is suspected to exist (for example, if there are
signs of external damage), the instrument must be immediately switched OFF. In the
event of this contact a qualified technician.
1.4.- Operating instructions
QNA-P/PV is a programmable instrument, with operating modes which may be
selected from the available programming menus.
Before starting the QNA-P/PV , carefully read the paragraphs on
INSTALLATION & STARTUP AND SETTING QNA-P/PV , to select the most suitable
operating mode for your requirements.
Note that when the instrument is switched on, the terminals may be
dangerous when touched and opening or removing parts may access
dangerous areas. Therefore, the instrument must not be used until it is
properly installed.
