5. DIODE AND BUZZER
Diode: Testing Voltage about 2.8 V, current about 1mA. The
approximate forward voltage drop in mV will be displayed.
Buzzer: The buzzer will sound when the resistance is less
than about 50 .
6. BATTERY TEST
Range
The working voltage of the
1.5V
battery will be displayed on
the LCD, so that the quality
9V
of the battery can be judged.
