7.3.3. Output Error
Should the load attached to the output terminals be too high in value (e.g. an open circuit), and the
set output is non-zero, a warning will be displayed at the base of the readout window. This condition
occurs when the xx51 is unable to provide sufficient compliance voltage to the load.
The “Output Error!” message will flash, alternating with the function and range displays.
While the output error condition exists, a drive voltage will remain on the terminals. As soon as an
acceptable value of load is connected, the warning message will disappear and the output current will
return to the displayed value.
7.3.4. High Current Interlock and Ramping
In the same way as for high volts, high current outputs (2A and above) feature a safety interlock
system. High current outputs will prompt a window to appear requiring confirmation from the user.
If the new current output selected is 2A (or more) greater than the present output, current ramping will
occur. During this process, the following window will appear:
The Stop Output button can be pressed during ramp up in order to zero the output if required.
If the new current output is 2A (or more) less than the present output, then ramping down of the
current will occur. The following window will appear during that process:
