TEST INSTRUMENT SAFETY

WARNING

Normal use of test equipment exposes you to a certain amount of danger from electrical shock because testing must sometimes be
performed where exposed voltage is present. An electrical shock causing 10 milliamps of current to pass through the heart will stop mos t
human heartbeats. Voltage as low as 35 volts dc or ac rms should be considered dangerous and hazardous since it can produce a lethal
current under certain conditions. Higher voltages pose an even greater threat because such voltage can more easily produce a lethal
current. Your normal work habits should include all accepted practices to prevent contact with exposed high voltage, and to steer current
away from your heart in case of accidental contact with a high voltage. You will sig nifi cant ly re duce the r isk fa ctor if yo u kno w and
observe the following safety precautions:

1. Don't expose high voltage needlessly. Remove housings and covers only when necessary. Turn off equipment while making test

connections in high-voltage circuits. Discharge high-voltage capacitors after remo ving power.

2. If possible, familiarize yourself with the equipment being tested and the location of its high voltage points. However, remember that

high voltage may appear at unexpected points in defective equipment.

3. Use an insulated floor material or a large, insulated floor mat to stand on, and an insulated work surface on which to place

equipment; and make certain such surfaces are not damp or wet.

4. Use the time proven "one hand in the pocket" technique while handling an instrument probe. Be particularly careful to avoid

contacting a nearby metal object that could provide a good ground return path.

5. When testing ac powered equipment, remember that ac line voltage is usually present on some power input circuits such as the on-

off switch, fuses, power transformer, etc. any time the equipment is connected to an ac outlet, even if the equipment is turned off.

INTRODUCTION

The B+K Precision Model 4010A Function Generator is a

versatile signal source which combines several functions into one
unit. A calibrated dial provides frequency accuracy within 5%.
High stability assures that the output frequency does not drift.

The heart of the function generator is a VCG (voltage-controlled
generator) that produces precision sine, square, or triangle waves
over the 0.2 Hz to 2 MHz range. This encompasses subaudible,
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 waveform converts the
instrument to a pulse generator capable of generating
rectangular waves or pulses, ramp or sawtooth waves, and
slewed sine waves.

In addition to the above features, an external signal may
be used to sweep the output frequency or control operating
frequency. This is useful in situations where an externally
controlled frequency is desirable.

With this versatility, the unit has a vast number of
applications in both analog and digital electronics in the
engineering, manufacturing, servicing, educational, and
hobbyist fields.
