*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 10 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 –555V (pattern 1), the
grid low voltage is –455V.
