*1. The negative value of the set value corresponds to the grid high
output voltage.
*2. The set values can be selected from the above 12 patterns only.
*3. The selected pattern determines the grid high voltage and the grid
low voltage.
If, for example, the grid high voltage is set to –480V (pattern 1), the
grid low voltage is –380V.
Operation/procedure
1. Enter the set value with the 10-key.
2. Press the [START] key.
Output is made with the entered value for 30sec. and the display
returns to the original state.
