Using the Current-Limiting Adjustment in C.V. Mode
1. Switch on the device.
2. Turn both the current adjustment knobs fully anticlockwise to the minimum, and
the voltage adjustment knobs fully clockwise to the maximum.
3. Short-circuit the output terminals by interconnecting them with the appropriate
cable (60 V/16 A DC cable).
4. Turn the current adjustment knob to the required current-limiting value. Use the
fine-tune knob if desired (where applicable). The C.C. indicator lights on the
display.
5. Remove the short-circuit cable from both output terminals.
6. Turn the voltage adjustment knob to the required value. Use the fine-tune knob if
desired (where applicable). The C.V. indicator lights up on the display.
7. Connect the load to the output terminals. If the current exceeds the current-
limiting point, the C.C. indicator lights up on the display.
Connecting the Load
• Connect the load.
• You can read the output current and the output voltage from the display as soon as
the device has been switched on.
• The C.V. indicator is lit if the device is in the C.V.-mode.
• The C.V. LED is off and the C.C. LED will light if the Amp display indicates a value
that exceeds the installed value. When this happens, the device will automatically
go into current-limiting mode. Install a load that will allow the device to function
normally.
6. 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.
