Sharp AR-M256 Service Manual

AR-M256/M257/M258/M316/M317/M318/5625/5631 SIMULATION 8 - 13
Operation/procedure
1. Touch the exposure mode to be changed.
The current set value is displayed.
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
(
∗) Linked with the destinations of SIM 26-6.
Linked with the auto exposure mode of SIM 46-19-1.
*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.
Operation/procedure
1. Touch the exposure mode to be changed.
