This instrument consists of input terminal, output terminal, amplification adjustment knob, power switch, power indicator light, etc.
This instrument is mainly used to amplify tiny currents and is used in conjunction with many experiments in teaching that require current amplification.
- Simple structure, easy to operate, easy to disassemble, simple and convenient to use.
When a small current is input to the instrument, the output of the instrument can drive the pointer of the ammeter to display the magnitude (qualitative) and direction of the current.
