Fluke PN 2430621 - Manual (Page 4)

80/81
Getting Started
2
Model 80 provides an output level from 20mV to 32Vp-p into open circuit or 10mV to 16Vp-
p into 50
Ω . DC offset plus amplitude are independently variable within two window levels:
±16V and ±1.6V (into open circuit). This special characteristics warrants production of extremely
small signals at an elevated DC environment.
Model 81 is a pulse/function generator and is also described in this manual. This instrument is
identical in its basic functions to the Model 80. In addition, this instrument offers Pulse and
Ramp waveforms. Pulse width and ramp width are adjustable within a range of 10.0ns to 999ms.
Model 81 provides control over the transition times for the leading and trailing edges; each can
be adjusted independently within a common range. Pulse complement and inverted ramp functions
are also available. This manual identifies those features and specifications that only apply to Model
81.
Instrument and Manual Identification
The serial number of the instrument is located on the rear panel of the instrument. The two
most significant digits identify instrument modifications. If this prefix differs from that listed on
the title page of this manual, there are differences between this manual and your instrument.
Technical corrections to this manual (if any) are listed in the back of this manual on an enclosed
MANUAL CHANGES sheet.
Options
Model 80 offers a rack mounting option; designated as OPT 001. Opt 001 is field installable
or may be ordered with new instruments from the factory.
Safety Considerations
Model 80 has been manufactured according to in- ternational safety standards. The instrument
meets EN 61010-1 and UL 1244 standards for safety of commercial electronic measuring and
test equipment for instruments with an exposed metal chassis that is directly connected to earth via
the power supply cable. Before the instrument is switched on, make sure that protective earth
terminal is connected to a protective earth via the power cord. Do not remove instrument covers
when operating or when power cord is connected to mains.
Any adjustment, maintenance and repair of the opened instrument under voltage should be
avoided as much as possible, but when inevitable, should be carried out only by a skilled person
who is aware of the hazard involved.
Safety Precautions
Protect yourself. Follow these precautions:
• Don’t bypass the power cord’s ground lead with two-
wire extension cords or plug adapters.
• Don’t disconnect the green and yellow safety-earth-
ground wire that connects the ground lug of the
power receptacle to the chassis ground terminal.
• Don’t plug in the power cord until directed to by the
installation instructions.
• Don’t repair the instrument unless you are qualified
electronics technician and know how to work with
hazardous voltages.
