You have just acquired a low frequency function generator; thank you for your
confidence in the quality of our products.
This instrument is compliant with safety standard NF EN 61010-1 (2001),
single insulation, concerning electronic measuring instruments. For optimal
service, read this manual carefully and observe the operating precautions.
Non-compliance with the warnings and/or operating instructions might damage
the unit and/or its components and might be dangerous for the user.
This instrument was designed for indoor use, in an environment with a
pollution degree of 2, at an altitude lower than 2000 m, a temperature
between 0°C and 50°C with a relative humidity lower than 80 % at up to
40°C.
The " MAIN OUT" , " SWEEP OUT" , " TTL OUT" outputs are protected for input
voltages not exceeding 60 VDC.
The " FREQ EXT" input may be used for measurements on category I
installations, for voltages never exceeding 300 V in relation to the earth.
Mains power supply: max. voltage 115 V to 230 V, depending on model.
CAT I :
The CAT I circuits are circuits protected by devices limiting low level
transient overvoltages.
Example : protected electronic circuits
CAT II : CAT II circuits are power supply circuits for domestic appliances or
similar, vulnerable to average-value transient overvoltages.
Example : power supply for domestic appliances and portable tools
CAT III : CAT III circuits are power supply circuits for power devices, vulnerable
to major transient overvoltages.
Example : power supply for industrial machines or devices
CAT IV : CAT IV circuits are circuits vulnerable to very high transient overvoltages.
Example : power inputs
Verify that the selection of power supply voltage corresponds to that of the
mains (see Functional Description chapter, operation).
Observe environmental and storage conditions.
Check the condition of the fuse and the power supply cable (three-wire
network: phase, neutral and earth) delivered with the unit compliant with
standard NF EN 61010-1 (2001) connected, on one side, to the instrument
and on the other, to the network.
A preheating of one half-hour ensures compliance with the above mentioned
technical characteristics.
Carefully read all the notes preceded by the symbol
Connect the instrument to a socket fitted with an earthing plug.
Do not obstruct air vents.
For safety, use only appropriate cables and accessories delivered with the
unit or certified by the manufacturer.
When the unit is connected to the measuring circuits, never touch an unused
terminal.
