Circuit Diagram:


Circuit Principle:
AMM-TE ammeter is mainly composed of ICL7107, power circuit, reference voltage source,
input circuit and display circuit.
1. ICL7107 is a BCD output integral type A/D conversion chip, its internal includes ;linear amplification,
  analog switch,oscillation,display driving etc.
2. Power circuit is divided into positive power and negative power; positive power is input by J2,C8 filtering;
  negative is composed of R8,Q1,L1,C6,C7,D2,D3 and ZD1,and generate -5V voltage is input by chip 26th pin.
3. Reference voltage source is composed of R1,R2,VR1,R9 and U2;36-pin is reference voltage input pin;
  adjust VR1 potentiometer to let 36-pin voltage be 100mV.
4. Input circuit is composed of J1,R5,R6 and C3.When the current of measured circuit passes through R5,
  it will generate a voltage on R5;this voltage will be input to chip 31-pin through R6 current limiting
  and be processed;C3 is input voltage filtering capacitor.
5. Display circuit is composed of DS1-DS4,D1,D4;4 digital tubes can be drived directly by the chip,
   R10 is current limiting resistance of DS1-DS3 digital tubes decimal points.

Finished Product Debugging:
1. After connecting with DC 5V (please notice the polarity), the digital tube will display -.000 or .000,this is normal.
2. Use multimeter to measure the voltage between chip 36-pin and 35-pin,and adjust VR1 potentiometer let it be 100mV

Key Points Voltage Reference Value:
1.Chip 1-pin and 21-pin voltage 5V
2.Chip 36-pin and 21-pin voltage 100mV
3.Chip 26-pin and 21-pin voltage -5V
