And a working state indicator lamp 4 is connected into a circuit of the precise constant-current constant-voltage 5 and used for judging whether the circuit is in a powered detection state. When the single-chip microcomputer detection control system 2 has abnormal conditions, the key indicator lamp 3 displays red to indicate that the precise constant-current and constant-voltage power supply 5 stops detection, but the actual condition is that the constant-current and constant-voltage power supply is still in a power-on detection state, and the working state indicator lamp 4 connected into the circuit of the precise constant-current and constant-voltage power supply 5 displays green at the moment, so that the fact that the constant-current and constant-voltage power supply does not stop working at the moment can be obviously judged.
