7. INITIAL SETTING OF ADJUSTMENT VALUE
Note:
Mode which sets the adjustment results recorded in the
If initial setting is performed, perform all adjustments again excluding the temperature compensation offset adjustment.
For details of the initial setting, refer to “4. Precautions on Adjustments” and execute the initial setting before the adjustment as required.
Setting Procedure :
1.Turn the =AMS + knob to display “ADJ CLEAR (C24)”.
2.Press the [YES] button. “Complete!” will be displayed mo- mentarily and initial setting will be executed, after which “ADJ CLEAR” will be displayed.
8. RECORDING AND DISPLAYING THE IOP INFORMATION
The IOP data can be recorded in the
Recording Procedure :
1.Turn the =AMS + knob to display “Iop Write” (C28), and press the [YES] button.
2.The display becomes Ref=@@@.@ (@ is an arbitrary num- ber) and the numbers which can be changed will blink.
3.Input the IOP value written on the optical
To select the number : Turn the = AMS + knob.
To select the digit : Press the = AMS + knob
4.When the [YES] button is pressed, the display becomes “Measu=@@@.@” (@ is an arbitrary number).
5.As the adjustment results are recorded for the 6 value. Leave it as it is and press the [YES] button.
6.“Complete!” will be displayed momentarily. The value will be recorded in the
Display Procedure :
1.Turn the = AMS + knob to display “Iop Read”(C27).
2.“@@.@/##.#” is displayed and the recorded contents are dis- played.
@@.@ indicates the IOP value labeled on the
3.To end, press the =AMS + button or [MENU/NO] but- ton to display “Iop Read”.
9. TEMPERATURE COMPENSATION OFFSET ADJUSTMENT
Save the temperature data at that time in the
Note :
1.Usually, do not perform this adjustment.
2.Perform this adjustment in an ambient temperature of 22 ˚C to 28 ˚C. Perform it immediately after the power is turned on when the internal temperature of the unit is the same as the ambient temperature of 22 ˚C to 28 ˚C.
3.When D101 has been replaced, perform this adjustment after the tem- perature of this part has become the ambient temperature.
Adjusting Procedure :
1.Turn the =AMS + knob and display “TEMP ADJUST” (C09).
2.Press the [YES] button and select the “TEMP ADJUST” mode.
3.“TEMP = 
[OK” and the current temperature data will be displayed.
4.To save the data, press the [YES] button.
When not saving the data, press the [MENU/NO] button.
5.When the [YES] button is pressed, “TEMP = 
SAVE” will be displayed and turned back to “TEMP ADJUST” display then. When the [MENU/NO] button is pressed, “TEMP AD- JUST” will be displayed immediately.
Specified Value :
The “TEMP = 
” should be within “E0 - EF”, “F0 - FF”, “00 - 0F”, “10 - 1F” and “20 - 2F”.

Adjusting Procedure :
1.Set the laser power meter on the objective lens of the optical
Connect the digital volt meter to CN110 pin 5 (I+3V) and CN110 pin 4 (IOP).
2.Turn the = AMS + knob and display “LDPWR AD- JUST” (C10).

3.Press the [YES] button once and display “LD 0.9 mW $ 
”.
4.Turn the =AMS + knob so that the reading of the laser power meter becomes 0.85 to 0.91 mW. Press the [YES] but- ton after setting the range knob of the laser power meter, and
save the adjustment results. (“LD SAVE $ 
” will be dis- played for a moment.)
5.Then “LD 7.0 mW $ 
” will be displayed.
6.Turn the =AMS + knob so that the reading of the laser power meter becomes 6.9 to 7.1 mW, press the [YES] button
and save it.
Note: Do not perform the emission with 7.0 mW more than 15 seconds continuously.
