terminal which is marked with the letter N or coloured Blue or
Black.
The wire which is coloured Brown must be connected to the
terminal marked with the letter L or P or coloured Brown or
Red.
If in doubt, consult the instructions provided with the equipment
or contact the supplier.
This cable/appliance should be protected by a suitably rated
and approved HBC mains fuse : refer to the rating information
on the equipment and/or user instructions for details. As a
guide, cable
of 0.75mm² should be protected by a 3A or 5A fuse. Larger
conductors would normally require 13A types, depending on
the connection method used.
Any moulded mains connector that requires removal
/replacement must be destroyed by removal of any fuse & fuse
carrier and disposed of immediately, as a plug with bared wires
is hazardous if a engaged in live socket. Any re-wiring must be
carried out in accordance with the information detailed on this
label.

INSTRUCTION MANUAL
2. INTRODUCTION
The Function Generator series are stable low distortion instruments
which generate signals in the frequency range up to 5MHz. Typical
applications include a wide range of audio response testing applications,
vibration testing, servo system evaluation, ultra sound applications, and etc.
These instruments include the following features: logarithmic and linear
sweep capabilities, together with a built in frequency counter. The sweep
capability simplifies the task of finding resonant points of speakers, filter
networks and other networks/structures. An oscilloscope may be connected
to this instrument for the response to be displayed. The counter can be
switched to measure and display the frequency of an external signal up to
150MHz.
l ADDITIONAL FEATURES
1.Low distortion waveforms (sine, triangular and square) and ramp signal.
2.Signal output in seven decade stages, 0.5Hz to 5MHz for GFG-8250A/8255A,
0.3Hz to 3MHz for GFG-8215A/8216A/8217A/8219A.
3.Adjustable sweep time and sweep width both in linear and logarithmic
modes.
4.Duty cycle control with signal inversion capability.
5.External Voltage controlled Frequency (VCF).
6.AM or FM modulation modes with internal or external modulation control.
