◎DC Power Supply: It offers a wide voltage and current range precisely.
◎Current meter (A): Accuracy 200μA ~ 200mA 4 ranges+(0.2% rdg + 2 digits)
2000mA ~ 20A 2 ranges+(0.3% rdg + 2 digits).
◎Voltage meter (V): Accuracy +(0.03% rdg + 4 digits).
◎Load: At full load.
◎Wires: The resistance of the wires must be small.

3. Output power :
Pout = Vout x Iout
Vout：Output voltage
Iout：Output current
4. Efficiency :
Efficiency = ^Pout x100%
Pin
Pout: Output power
Pin: Input power
5. Voltage accuracy:
│Vout-Vout(nominal)│
Vout
x100%
Vout：Output voltage
Vout(nominal)：Nominal output voltage
