Running a Predefined Voltage/Current Programme
The software allows you to define a series of voltage/current settings for the output, and let them run
automatically. To set up the programme:
1. Click the ProgramForm tab.
2. In the table, enter the desired voltages, currents, and time (in seconds).
3. In the loop box, select how many times the programme has to run:
o
Select infinite to let the programme run infinitely until you stop it
manually.
o
Select a number from the selection list.
o
Or click in the loop box and type the required number.
4. Click the Run button to start the programme.
5. Click the Stop button to pause the programme. Click Run again and the
programme continues where it was stopped.
6. Click the MainScreen tab to see the evolution of voltage and current in the
graphs while the programme runs.
Exiting from PC Remote Control Mode
1. Close the remote control software.
2. Disconnect the USB/RS232 cable from the back of the power supply.
You hear a tone from the power supply to indicate that remote control mode is no longer active. The
keys on the front panel are unlocked automatically (this may take a few seconds).
Troubleshooting
If you are experiencing problems, check if the pc’s COM port is set up correctly:
• bits per second: 9600
• parity bit: none
• data bits: 8
• stop bits: 1
• data flow control: none.
To check the functionality, run this query command via a terminal application such as MTTTY:
*ldn?
This should return the identification information (model name, serial number) of the power supply.
11. Cleaning and Maintenance
• Disconnect the device from the mains prior to maintenance activities.
• The power supply cables must not show any damage. Have a qualified technician maintain the
device.
• Wipe the device regularly with a moist, lint-free cloth. Do not use alcohol or solvents.
• There are no user-serviceable parts, apart from the fuse. Contact your dealer for spare parts if
necessary.
• Store the device in a dry, well-ventilated, dust-free room.
Replacing the Fuse
Only replace the fuse by a fuse of the same type and rating.
1. Before replacing the fuse, unplug the mains lead.
2. Wedge the fuse holder out of its housing with a flat-head screwdriver.
3. Remove the damaged fuse from its holder and replace with the exact same type of fuse.
4. Insert the fuse holder back in its place and reconnect power.
