.

              c. Select a reliable six-and-a-half digital voltmeter with a  current test 

                   range more than 5A.

2.1.2 Output Calibration Steps:

[Step 1]

               Press

 [SHIFT][4]

 to display Password input window, input Password 

               (293856) by using the number keys, and the Calibration window will

                appear. If an incorrect password is entered, the unit returns to the 

                home screen. 

[Step 2] 

               Control the cursor by using the arrows assigned to the 8, 2, 4, 6 keys. 

               Set the cursor to the calibrated item of the corresponding channel, and

               using a connected voltmeter  for correct readings, use the rotary knob 

               to adjust parameters and regulate the voltage of the corresponding  

               channel to a 0V reading on the voltmeter.  Press

 [ENTER]

 to store the 

               calibration data of the corresponding channel. Move the cursor down 

               to calibrate the other channels with the same procedure. 

               Tip: Use the F/C feature to switch between broad and precise incremental

               control.
