The reverse operating mode change can also occur if the load resistance is increased to the
point that the required load current drops below the I
SET
value. At that point the power
supply would crossover to CV mode and the load current would be free to vary as the load
resistance changed.
Figure 12: Operating Modes
To set the voltage set point (VSET)
:
1.
Turn the 9-position mode control to the VOLTS position or press the rotary
Adjust/Enter control if the 9-position mode control is already at the VOLTS
position.
The voltage set point is blinking in the output voltage display. The output current will be
displayed in the output current display.
2.
Set the desired voltage value using the rotary Adjust/Enter control.
Important:
If you can't get the set point to the desired level, you may need to
change the set points for OVP.
3.
Press the rotary Adjust/Enter control to transition to Fine Adjust mode.
The set point will blink faster to indicate fine adjust tracking mode.
4.
Set the desired voltage value using the rotary Adjust/Enter control.
5.
Once the desired value has been set, press the rotary Adjust/Enter control to
commit the setting.
Important:
The control circuits have been designed to allow you to set the
output voltage up to 105% over the model-rated maximum value. The power
supply will operate within these extended ranges, but full performance to
specification is not guaranteed.
Quick Tip: Remote
operation uses these
SCPI commands. See
