Requirements
When using test fixtures, keep the lid closed while power is applied
to the device under test. Carefully read the Safety Precautions
instructions that are supplied with your test fixtures.
Before performing any maintenance, disconnect the line cord and
all test cables. Only qualified service personnel should perform
maintenance.
The instrument has been inspected for mechanical and electrical
performance before shipment from the factory. It is free of physical
defects and in perfect electrical order. Check the instrument for
damage in transit and perform the electrical procedures outlined in
the section entitled Unpacking and Initial Inspection.
The function generator may be operated from a wide range of
mains voltage 85 to 265 Vac. Voltage selection is automatic and
does not require switch setting. The instrument operates over the
power mains frequency range of 48 to 63Hz. Always verify that the
operating power mains voltage is the same as that specified on the
rear panel.
The 2074 should be operated from a power source with its neutral
at or near ground (earth potential). The instrument is not intended
for operation from two phases of a multi-phase ac system or across
the legs of a single-phase, three-wire ac power system. Crest factor
(ratio of peak voltage to rms.) should be typically within the range of
1.3 to 1.6 at 10% of the nominal rms. mains voltage.
To ensure the safety of operating personnel, the U.S. O.S.H.A.
(Occupational Safety
engineering practice mandate that the instrument panel and
enclosure be "earth" grounded.
isolated from the front panel, the metal part is connected to earth
ground.
Do not attempt to float the output from ground as it may
damage the Model 2074 and your equipment.
