Purposes
For some experiment of electronic, a current source is essential. Below there are two
samples:
1.Measure the external characteristics of the current source
Adjust the dc current source output to 10mA, set R, to 1K ohm and respectively.
and adjust potentiometer R, (from 0 to 1K ohm), then measure several pair the
voltmeter and ammeter readings and verify the external characteristics.
2.Determine the conditions of equivalent transformation of power source
Record the voltmeter and ammeter values of the voltage source circuit. Adjust the
output current Is of the current source to make the readings of the two meters equal
to the recorded values and verify the correctness of equivalent transformation
conditions.
Features:
- Constant current output
- Continuously adjustable output current
- high stability 0.01%
- Open circuit and over voltage protection
- 3 1/2 digit LCD current meter with backlight
- Compact, light and safety
