AR-M208 SIMULATION 8 - 3
The input value is in the increment of –25V.
( ) Linked with the destinations of SIM 26-6.
Linked with the auto exposure mode of SIM 46-19-1.
* SUPER PHOTO (5:) cannot be executed.
When [OK] or [START] key is pressed, a caution buzzer sounds.
(Only the adjustment value can be entered.)
*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
low voltage.
If, for example, the grid high voltage is set to –480V (pattern 1), the
grid low voltage is –350V.
Operation/procedure
After selecting the mode, enter the adjustment value and press the
[OK] key, and output will be made for 30sec.
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.
Operation/procedure
After selecting the mode, enter the adjustment value and press the
[OK] key, and output will be made for 30sec.
The input value is in the increment of –25V.
