3) Frequency phase for choice Press(8) of the buttons and rotate to (4) or (5)
according to what your need, the display reading can be shown on(2)
4) Output voltage balance adjustment The output voltage balance may be
adjusted continually by (3), also may be adjusted by maxed (6) of 60dB. The
message can be output by socket (7)
8. Using in workshop
1)
Sine wave shaking and burning appliance
There are some characters as the message source of the sine wave aas follows:
1.1May test the distortion because of it has low distortion message
1.2May test the frequency width of the amplifier
1.3May test the amplifier maxed adding with the accurate alternator
1.4 May be regarded as message source about the impedance test the electric
bridge
2)Testing the maxed adding about the amplifier
One example of testing the maxed adding about the amplifier:
Connect the machine according to drawing 4 with the tested amplifier, alternating
current &voltage meter.
2.1 Adjust the attenuator (6) and the button (3) and find the reading of IV on the
alternating voltage meter of the amplifier. Set the output voltage balance
stated form 20c1B.
2.2 Use another alternating voltage meter to measure the voltage of the input
end on the amplifier and calculate the adding amounts.

7. Output ending : Output the setting message from it
8. Frequency range setting: May preset 6 phases
X1 shift : 0.2Hz- 20Hz
X10 shift : 2Hz-200Hz
X100 shift : 20Hz-2KHz
X1K shift : 200Hz-20KHz
X 10K shift : 2KHz-200KHz
X100K shift : 20KHz-2MHz
9. Output wave for choice : The machine will display the sine wave if press to
The machine will display the square wave if press to
10. The Unit of the frequency (Hz and KHz)
6. Back panel
11. Power source of input alternating current
12. Fuse seat
7. Operation indication
1. Turn on the machine : Please confirm whether the voltage setting (11) is right or
not before turning on the machine. After checking press (1), frequency display
(2) will be on shine and display the correct message for output.It shows that the
machine is starting working. Please wait for 3 minutes and make the machine
steady and can be put into use.
2) Wave for choice : Output the sine wave if press (9) on the shift and output the
square wave if press on the shift.
