2. To modify the frequency to 850Hz.   
Press                or                to move flash digit to “ 2 ” position
.
 
Then turn the Rotate Knob clockwise until the digit become to “ 8 ”. 
 
6.4 The Setup of Amplitude 
 Set to 
Main Amplitude entry mode
 by pressing                button to
, now the  AMPL 
LED (In parameter display area B) will be flashing. 
 
 Key in the desired value of Amplitude. 
 Select a proper unit-button to specify the value. 
  In  addition,  you  can  use                or                and  the  Rotate  Knob  to  modify 
the main Amplitude value you need. 
 
 Example of the Setup Amplitude 
1.  To set Amplitude at 8 Vpp.   
Press                first, then key in                and press                . 
2.    To modify the Amplitude to 5 Vpp.   
Press                or                to move flash digit to “ 8 ” position. 
Then turn the Rotate Knob anti-clockwise until the digit become to “ 5 ”. 
 
The input limit : (1) Amplitude should be among 0.01 ~ 10Vpp. 
(2) Offset should be among ±5Vpp. 
(3) AMPL + |2 × OFFSET| ≤ 10Vpp. 
 
6.5 The Setup of Offset 
  Set  to m
ain DC  offset  Voltage entry mode by
  pressing                button, now  the 
 
OFFS LED (In parameter display area B) will be flashing.
 
 Key in the desired value of DC offset voltage. 
 Select a proper unit-button to specify the value. 
 In addition, you can use                                and the Rotate Knob to modify the   
main DC offset voltage value you need. 
 
 Example of the Setup Offset 
1. To set DC offset voltage at 1 Vpp. 
Press                first, then key in                and press                . 
2. To modify offset voltage to 2 Vpp.   
Press                or                to move flash digit to “ 1 ” position. 
Then turn the Rotate Knob clockwise until the digit become to “ 2 ”. 
 
The input limit : (1) Amplitude should be among 0.01 ~ 10Vpp. 
(2) Offset should be among ±5Vpp. 
(3) AMPL + |2 × OFFSET| ≤ 10Vpp.
