7.2.3. HV interlock and ramping
A safety interlock feature is incorporated to ensure that user must undertake an additional operation
when voltages about 40V are selected.
To prevent potential damage to equipment being calibrated, large changes in the voltage setting
cause the xx51 to change the output by a controlled ramp (instantaneous change is not permitted).
Press OK to confirm the output or Cancel to return to the previous output setting.
In addition, if the voltage selected is 100V (or more) greater than the present output level, ramping of
the voltage will occur at approximately 200V per second. During this process, the following window
will be displayed:
Note, if necessary you may use the Stop Output button during ramp up to immediately set the output
voltage to zero.
Ramping down of the voltage will occur if the requested new output level is 100V (or more) lower than
the present output. This window will be displayed during ramp down:
