Sharp AR-M276

AR-M236/M276/M237/M277 SIMULATION 8 - 12
*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
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

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.
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 [START] key.
