III. Instructions

1.Connect the current amplifier with the tested product according to the testing requirements, and make sure that there's power supply. (For split type, connect the "input" on the panel with the power, the "output" with the "input" on DDK, and the "instrument" with the "instrument" on DDK.

2.Select the position of Current Switch according to the needed current.

3.Turn on the power, and the green light should be on (if not, turn the Voltage Switch counterclockwise to zero until the green light is on). Press the Startup Button, the green light should be off and the red light is on. Turn the Voltage Switch clockwise until the current rises to the needed level.

4.Turn the Voltage Switch counterclockwise to zero, press the Stop Button, the red light is off and the green light is on. The testing is over.

V. Maintenance Notes
1. when acceptance of goods, please check the main circuit terminal block if it is loose, or if elecrical brush of regulator is with a  good contact.

2. when not using for a long time, please check the main circuit of insulation earth resistance with 500V Megohmmeter before the equipment will be used, the resistance should be not less than 0.5 MΩ.

3. Input voltage value should be ± 10%, frequency 50HZ.

4. Current switch are not allowed to operate with load.

5. Operation should be equably & slowly rotating hand wheel to avoid damaging the regulator.

6. Full load hours should not exceed 5 minutes, continuous work time should be less than 2.5 minutes, but the working cycle should be more than 10 minutes.

7. Earth terminal should be well grounded.
