The minimum increment is 2V.
The result of (Set value – 199) / 2 is stored in the EEPROM.
When reading a value from the EEPROM, the value of (EEP value *2)
+ 200 is used as the set value.
Therefore, the set value entered must be an even number. If an odd
number is entered the entered odd number + 1 is displayed after
pressing [OK] key.

The input value is in the increment of –25V.
*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 8 patterns only.
*3. The selected pattern determines the grid high voltage and the grid

If, for example, the grid high voltage is set to –480V (pattern 1), the
grid low voltage is –350V.
If, for example, the grid high voltage is set to –480V (pattern 1), the
