RS232 Baud rate: 4800/9600/19200/38400/57600/115200. Data bit: 8; check 
bit: NONE, ODD, EVEN; stop bit: 1~2; 
LAN parameters include Gateway address (Gateway), IP address (IP), Mask 
address (Mask) and port (Socket Port). 
When communication with computer, you need to select a communication 
interface and set its corresponding configurations so that the communication 
settings of the power supply are same with the PC configurations. 
Config menu 
The configuration menu is described below: 
Volt-Min: 
Voltage lower limit setting 
Voltage upper limit setting 
Frequency lower limit setting 
Frequency upper limit setting 
Current RMS upper limit setting
Select BNC composite terminal function

Set 3-phase AC power supply function 
Switch current measurement mode 
 
Switch current measurement mode (Meas-Curr-mode) 
This item can set the current measurement mode of the power supply. IT7300 
Series has two measurement modes: Auto and Manual. When Auto mode is 
chosen, the switchover among High range, Middle range and Low range will be 
performed by the instrument automatically. When Manual mode is chosen, the 
switchover among High range, Middle range and Low range will be performed 
by the user manually.

3.10.1 Sweep 
The Sweep function is used to test efficiency of switching power supply and 
capture the voltage and frequency at the maximum power point. The voltage 
and frequency of power may be altered in the form of step ladder by setting the
