Safety Summary
Please take a moment to read these operating instructions thoroughly and completely before
operating this instrument. Pay particular attention to WARNINGS used for conditions and actions that
may pose a hazard to the user and CAUTIONS used for conditions and actions that may damage the
instrument.
Always inspect the instrument and other accessories for any sign of damage or abnormality
before every use.
Never ground yourself and keep your body isolated from ground.
Never touch exposed wiring, connections or any live circuit conductors.
Do not install substitute parts or perform any unauthorized modification to the instrument.
Use caution when working above 60V DC or 30V AC rms. Such voltages pose a shock hazard.
Remember that line voltage is present on some power input circuit points such as on-off switches,
fuse, power transformers, etc., even when the equipment is turn off.
Also, remember that high voltage may appear at unexpected points in defective equipment.

1. Model 4005 PRODUCT DESCRIPTION
1-1. Introduction
The 4005 is designed to be used as a FUNCTION GENERATOR, SWEEP GENERATOR, PULSE
GENERATOR and a FREQUENCY COUNTER, offering a wide range of applications in both analog
and digital electronics such as engineering, manufacturing, servicing, education and hobbyist fields.
VCF (voltage controlled frequency) produces precision sine, square and triangle waves over the
0.05Hz to 5MHz for sub-audible, audio, ultrasonic and RF applications. A continuously variable DC
offset allows the output to be injected directly into circuits at the correct bias level.
Variable symmetry of the output waveforms converts the instrument to a pulse generator capable of
generating rectangular waves or pulses, ramp or sawtooth waves and skewed sine waves of variable
duty cycle. The sweep generator offers linear sweep with variable sweep rate and sweep width up to
100:1 frequency change. The frequency response of any active or passive device up to 5 MHz can be
determined.

2-1. Initial Inspection
This instrument was carefully inspected both mechanically and electrically before shipment. It should
be physically free of damage. To confirm this, the instrument should be inspected for physical
damage in transit. Also, check that supplied accessories are present and correct.
2-2. Connecting AC Power
This instrument requires 115V AC or 230V AC (50-60 Hz) power socket with protective earth contact
(PE-contact).
CAUTION
AC POWER OF THIS INSTRUMENT IS PRESET TO 115V IN FACTORY. BEFORE POWERING
ON THIS INSTRUMENT, CHECK AND MAKE SURE THE VOLTAGE OF THE POWER SOURCE IS
SAME WITH THE MARKING OF UNIT.
FOR USE WITH AC230V, THE VOLTAGE SELECTOR (on rear panel) SHOULD BE SWITCHED
TO THE 230V POSITION.
2-3. Cooling and Ventilation
No special cooling and ventilation is required. However, the instrument should be operated where the
ambient temperature is maintained.
2-4. Position
This instrument is built as a bench-type instrument with rubber feet and tilt stand in place. Stand-up
angle can be adjusted by rotating angle of carrying handle.
2-5. WARM-UP
Allow 30 minutes for the unit to warm up so that it is stabilized and ready for use.
