Press the left-
hand “UP” fast change button to increase the frequency and the “DOWN” button to
decrease. These controls are time sensitive and the rate of frequency change will increase if the
button is held in. The main frequency control is a step actuator and can rotate any number of
revolutions is either direction. It is used to make small frequency adjustments with one step giving one
increment of the frequency. Note that the frequency resolution changes across the full range. A single
step on the frequency control gives 1Hz change between 1kHz and 2kHz. At other values the
resolution is different -see the specification on the back page.
C.R.O.
The CRO sockets are for monitoring by Cathode Ray Oscilloscope or for use as a signal source for
electronic circuits. Only a high impedance load should be connected (>600Ω).
EXTERNAL LOUDSPEAKER
An external speaker or vibration transducer may be connected to the red and black sockets. For best
results use an external speaker of impedance 8Ω or greater. Vibration transducers can be used less
than 8Ω impedance
But at full power the wave “shape” can be affected. When using low impedance transducers or
loudspeakers at high powers for prolonged periods allow adequate ventilation around the case to
dissipate any heat generated. This is best ensured by
not
having the case flat with its back on the
bench.
