Show circuit 3, the battery capacity indication circuit 3 include the first audion Q1, first resistor R1, second resistance R2,3rd resistor R3,
Four resistance R4, the 5th resistance R5, the 6th resistance R6, the 7th resistance R7, the second audion Q2, Zener diode Z1, the 8th resistance
R8, electric capacity C1 and bi-colour LED LED2, the emitter stage of the first audion Q1 are connected to controlling switch SW1 and are indicated with load
On the junction point of lamp 2, the colelctor electrode of the first audion Q1 by the green light of first resistor R1 and bi-colour LED LED2 just
Pole is connected, and the base stage of the first audion Q1 is connected on the colelctor electrode of the second audion Q2 by 3rd resistor R3, institute
The grounded emitter of the second audion Q2 is stated, the base stage of the second audion Q2 is gone here and there by the 7th resistance R7, the 5th resistance R5
It is grounded after connection circuit, the colelctor electrode of the second audion Q2 is connected to the red light of bi-colour LED LED2 by the 8th resistance R8
Positive pole is connected, and the minus earth of the bi-colour LED LED2, the electric capacity C1 are in parallel with the 5th resistance R5, described
