on the 7-segment LED display.
2.
Disconnect the USB cable.
When correct detection occurs, execution automatically advances to the
next test item.
* If an error occurs, execution does not advance to the next test item.
2. Current-consumption Check, Voltage
Detection Check and SW/LED Check
1.
Verify that all LEDs are lighted.
Verify that the voltage of the stabilized power supply is
9 V
.
2.
Measure the current consumption and verify that it is between
140
and
170 mA
.
3.
Set the voltage of the stabilized power supply to
6.5 V
.
Verify that bt appears on the 7-segment LED display.

4.
Set the voltage of the stabilized power supply to 7.5 V .
Verify that the all LEDs light up.
5.
Set the voltage of the stabilized power supply to
9.0 V
.
6.
