1.3.- Safety advice.
For safety reasons it is essential that anyone installing or handling the
QNA-412 follows the usual safety procedures as well as the specific
warnings in this instruction manual.
If the equipment is used in a way not specified by the manufacturer,
the equipment's protection may be compromised.
When it is likely that a loss of protection has occurred (for example visible
damage) the equipment must be disconnected from the supply. In this event contact
a qualified service representative.
1.4.- Operating instructions.
The QNA-412 is programmable, measuring instrument offering a series of
options that may be selected using the set up menus.
Before installing the equipment and taking measurements carefully read
sections INSTALLATION, START-UP and SETTING for the QNA-412 analyzer.
Select the most suitable way of obtaining the required data.
It must be remembered that once the equipment is connected, the
terminals may be dangerous when touched and opening the covers or
removing pieces may access parts that are dangerous when touched. The
equipment must not be used until it is fully installed.
