Mains Operating Voltage
Check that the instrument operating voltage marked on the rear panel is suitable for the local
supply.
Mains Lead
Connect the instrument to the AC supply using the mains lead provided. Should a mains plug be
required for a different mains outlet socket, a suitably rated and approved mains lead set should
be used which is fitted with the required wall plug and an IEC60320 C13 connector for the
instrument end. To determine the minimum current rating of the lead-set for the intended AC
supply, refer to the power rating information on the equipment or in the Specification.
Any interruption of the mains earth conductor inside or outside the instrument will make the
instrument dangerous. Intentional interruption is prohibited.
Output Terminals
All power connections are made from the front panel.
The load should be connected to the positive (red) and negative (black) terminals marked
OUTPUT. Both are fully floating and either can be connected to ground.
The terminal marked
USB
The USB port is connected to instrument ground. It conforms with USB 2.0 (Full Speed) and
accepts a standard USB cable. The Windows plug-and-play functions should automatically
recognise that the instrument has been connected. If the correct driver is not found, follow the
Windows on-screen prompts and install the required files from the CD supplied.
Setting Up the Output
With the POWER switch on (
accurately preset using the VOLTAGE and CURRENT controls; the left-hand meter shows the set
voltage and the right-hand meter shows the set maximum current.
When the
preset voltage but the right-hand meter now shows the actual load current.
At power on, the output voltage, current limit and
power off.
Constant Voltage
The output voltage is adjusted using the coarse and fine VOLTAGE controls; the coarse control
changes the voltage in 100mV steps and the fine control in 10mV steps. The CURRENT control
sets the maximum current that can be supplied; the control changes the current in 10mA steps.
Constant Current
If the load resistance is low enough such that, at the output voltage set, a current greater than
the current limit setting would flow, the power supply will automatically move into constant current
