三、Instructions
3-1 Preparation prior to power：
（1）Confirm that the input voltage in the range of nominal (AC198-242 v, 50
hz). AC110V 60 hz input there will be a special label to facilitate heat
dissipation。
（2） power supply should have at least 10 cm above the heat dissipation
space around, working environment temperature is not higher than 40 , ℃
humidity < 80%, cannot be used in acid gas, where excessive amounts of dust.
To prevent the rain, sun, violent vibration.
3-2 Operational approach：
（1）operational approach
（2）Puts the power "ON" position, indicating lights, LED display.
（3）Voltage Settings: 6 to adjust the steady flow knob clockwise, the largest
4 to the required voltage regulating voltage regulator knob, connects the load
to the output very eight straight, the negative 10 (pay attention to the positive
and negative polarity correctly), the voltage indicator lights up 3. Work in the
stabilized state power, i.e., constant voltage, the current changes over load.
（4）Steady flow Settings: regulating voltage setting knob 4 make the output
voltage of 3-5 v arbitrary value, then 6 set steady flow knob counterclockwise
to the minimum. With wire short circuit output positive 8, 10, the cathode
adjustment needed for steady flow setting knob 6 to current value, and then the
