Example of application
1. Apply V
CC
=
5V and measure V
O

0
at V

0
at V
O
2.
2. In order to stabilize output voltage measure 3. to 5. on the LED lighting condition shown in Fig.3 for example.
3. Measure the output voltage V
O
2 and adjust I
FM
in order to fix
V
O

1
(determine value by your actual application). After the
adjustment, memorize the values, V
O
1, V
O
2 and I
FM
, (If there are the initial memorized values, V
O
1, V
O
2 and I
FM
, measure V
O
1 and
V
O
2 at memorized I
FM
. If there are difference between the measured values and memorized values adjust I
FM
to let V
O
1 and V
O
2 be
initial values.)
4. Attach the color toner and measure the output voltage at V
O
1 (I
FM
at the value memorized at 3.). Determine the ouput voltage
difference
V
O
1 between the measured value and memorized value V
O
1 at 3, and adjust the attached color toner amount.
5. Attach the black toner and measure the output voltage at V
O
2 (I
FM
at the value memorized at 3.). Determine the ouput voltage
difference
V
O
2 between the measured value and memorized value V
O
2 at 3, and adjust the attached black toner amount.
6. After the measurement, set I
FM
=
0mA and turn off the LED.
7. To measure them again, start from 1.
