AR-M256/M257/M258/M316/M317/M318/5625/5631 SIMULATION 8 - 15
Operation/procedure
1. Touch the exposure mode to be changed.
The current set value is highlighted.
2. Enter the set value with the 10-key.
3. Press the [START] key.
Output is made with the entered value for 30sec, and the display
returns to the original state.
Min. unit: 25V increment
*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 –605V (pattern 1), the
grid low voltage is –505V.
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.
The minimum increment is 2V.
The result of (Set value-200) / 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, an even number must be entered. If not, the entered odd
number +1 is displayed after pressing [START] key.
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.
Min. unit: 25V increment
