Controls:
The COARSE FREQUENCY control selects the decade range:
10 to 110Hz, 0.1 to 1.1kHz
1 to 11 kHz or 10 to 110kHz
The large control sweeps the output frequency from 1 to 11, to
cover the selected decade range.
Pressing SPEAKER On/Off turns the internal speaker On and
Off. It has a useful response from 100Hz to15kHz. Default is
Off.
The WAVEFORM button toggles between sine and square
waveforms. The LED indicates the current selection. Default is
sine.
OUTPUT LEVEL controls the overall output level or amplitude.
Although the output is intended for input to oscilloscopes and
electronic circuits, it will give useful output via a small
loudspeaker, with an impedance of around 65Ω.
The output from the two yellow sockets ‘floats’, i.e. it is not referenced to earth (zero volts). Using either of the
yellow sockets together with the green ground/earth socket, provides a signal referenced to zero volts.
Ground/Earth socket: this is a true Earth, connected to the case of the unit and also to the Earth conductor in
the mains lead.
Mains lead and fuse replacement
The mains cable stows on the back of the unit with a wind and clip feature. The mains cable retainer can be
removed to allow the cable to be stored separately. Simply remove the screw and retainer from the base of
the unit. The IEC cable is now detachable.
