5. USAGE DESCRIPTION
The function generator can provide versatile waveforms of high
efficiency and convenient operation. Familiarize yourselves with the
function thoroughly through Operation Manual and practice with all
accurate operation procedures can lead you to easily master the
performance of the Function Generator.
It is one of the best ways to observe waveforms by connecting the
instrument to Oscilloscope. Watch the effect in different control of
waveforms through Oscilloscope carefully when proceeding the following
steps:
5-1.First-step check:
(1)
Ensure that the voltage of the main supply is compatible with this
instrument. The label on the rear panel states the required AC voltage.
(2)
Connect the instrument to the main supply using the power cord
supplied.
(3)
Press PWR switch
1
and ensure all the rotary controls are pushed in,
then rotate AMPL
12
knob to make the indication point up forward.
(4)
Rotate the FREQ
13
control fully anticlockwise.
