3. Move the cursor by pressing ( ◄, ► ) to the command line of "I
P s e t = 1 5 5 0 . 0 0 W
4. Press 3 , 0 then press ENTER to change the value to "30.00".
P s e t = 1 5 5 0 . 0 0 W
5. After setting the parameter of the load, the LOAD ON/OFF key should be pressed to turn
on the load, so that the load can sink the current. (The detailed information please refers
section 3.4.5.)
If there is error during the procedures of inputting value, press CLEAR to
clear the value at any time and then input again.

3.16 DC Load Simulation -- Rectified Load Mode

The general DC input/AC output products such as DC to AC inverter; its input current is not
always DC. However, the load current is often similar to the current loaded by rectified load,
thus this mode is designed to simulate a period of load current under CC mode.
Press RLC/DC RECT key to go into the DC Rectified mode, users can set the I
select the LINE SYNC to be the reference loading frequency, the maximum current value
I (max) of UUT is also required to be set.

The load current under rectified mode is shown as Figure 3-15, 3-16 and 3-17. This load
current is rectified sine wave so needs to set CF value.
If users do not choose LINE SYNC as reference period then set loading frequency is needed
as below shown.
