8. Using the control knobs
1. The rotary encoder control knobs have fine and coarse tuning with clicking movement. Push the
knobs to toggle between coarse and fine tuning, notice the subtle changes in brightness of
related LED.
2. Adjust the knobs to your desired values by trying coarse and fine tuning. The display will resume
its normal brightness after few seconds to confirm your adjustment.
3. Connect the equipment to the power supply. Red (+) is connected to the positive polarity input of
the equipment and Black (-) is connected to the negative polarity input of the equipment.
4. Switch on the power supply first and the panel meter & green CV Indicator should light up again.
5. Switch on the equipment and the panel meter & green CV Indicator should still remain in green.
6. You can now operate the equipment. When an operation is finished, switch off the equipment
first and then switch off the power supply.
9. Remote Control Mode
9.1. Remote Control Mode (P 1525 / 1535)
There are two methods for remote control of current and voltage adjustment.
Both methods require current remote control part to be set up in order for remote control mode to be
functional, otherwise unit will be in CC mode all the time.
Method A:
Using two external variable DC voltage sources.

Check the output voltage range of the power supply by varying the external voltage source.
Short circuit the main output with 10AWG (5,3mm2) wire to check the display for CC setting varying
the external voltage source.
