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.
