Outputs
The load(s) should be connected to the positive (red) and negative (black) terminals marked
OUTPUT, on the front panel.
Remote sense connections to the load, if required, are made from the positive (red) and negative
(black) SENSE terminals. The shorting links between OUTPUT and SENSE terminals should be
removed when remote sensing is required. Replace the shorting links (red SENSE to red
OUTPUT, black SENSE to black OUTPUT) when remote sensing is not in use.
The green terminal marked
Inputs
The RS232 and GPIB (IEEE-488) interface connectors are situated on the rear panel. Signal
grounds are connected to safety earth ground. Further details are given in the REMOTE
OPERATION section.
Main Outputs
Setting Up the Output
With the power switch ON and the output switch OFF the output voltage and current limit may be
accurately set using the three output controls prior to connection to the load. The left hand meter
indicates voltage and the right hand meter indicates current.
With the output switch in the OFF (set) position, the current meter shows the value of the current
limit setting (indicated by all the decimal points coming on); with the output switch ON, it shows
the value of load current flowing.
Unless remote sensing is required the shorting bars should be placed from + sense to + output
and from - sense to - output. Ensure that the terminals are properly tightened before use.
Constant Voltage
The voltage output is set using the coarse and fine voltage controls; the current control sets the
maximum current that can be supplied.
Constant Current
If the load resistance is low enough such that, at the set level of output voltage, a current greater
than the current limit setting would flow, the supply will automatically move into constant current
operation.
The current output is set using the current limit control; the voltage controls set the maximum
voltage that can be generated.
Constant Current Indication
When the unit is operating in constant current mode, either by intention or because the current
limit point has been reached, the decimal points on the current meter will flash to indicate
constant current rather than constant voltage operation.
Instantaneous Current Output
The current limit control can be set to limit the continuous output current to levels down to 1 mA.
However, in common with all precision bench power supplies, a capacitor is connected across the
is connected to the chassis and safety earth ground.
