at the minimum position.
3. Plug into AC outlet, and then turn on the power switch (1). Check to make sure the fan is working.
4. Turn on the output (3). Select switch (4) to either "CV" or "CC" as your operating mode. If "CV" is
selected, the output voltage will be stable while the output current will change with the load; likewise, if
"CC" is selected, the output current will be stable while the voltage will change with the load.
5. Adjust knob (2) to set the output to the desired level.
IV. Maintenance
Routine inspection and maintenance is required for prolonged working life of the rectifiers:
1. Clean dust off the inside of the rectifier and cooling fan.
2. Clean off the oxide layer that may occur on the output copper wires and connectors.
3. Check to ensure that cooling fan is in good working condition all the time, replace the fan if it fails.
4. Regularly check and ensure that switch and circuit breaker are in good working condition and all
connectors are secure and firm.
5. The rectifier should not sit idle for more than a year, as the capacitor may change its characteristics if
not charged for a long time.
