4-18. Changes that are not deferred
In deferred mode, changes to all fields are deferred with the following exceptions.
Line Locking.
Change of harmonic edit mode (e.g. Absolute RMS, % of RMS etc).
Power calculation method.
Selection of Phase Units (Degrees/Radians).
Selection of 2 Wire/4 Wire because terminal configuration cannot be changed when the
output is on.
Global settings Time/Date and GPIB settings cannot be changed in deferred mode.
Load/Save setup is not available in deferred mode
Note: Entry into calibration mode automatically selects Direct Mode.
4-19. Setting up voltage and current waveforms
The following describes setting up voltage waveforms but applies equally to current.
Navigate to the Output Menu and use the cursor up/down keys until the voltage or current
channel to be set up is highlighted. Notice that the N-phase Voltage channel is, by
default, limited to 33 Volts. The N-phase channel can be set to provide up to 1000 Volts
if required.
To avoid electrical shock hazard, disconnect the 'N' phase
voltage Hi terminal from any 6140A Lo terminal before electing
to override the limit.
To override the limit; select the N-phase Voltage channel in the Output Menu. Select the
Waveform Menu. With the N-phase output set to Off, check the Override Limit box.
