Syntax:
DISPlay:CONTrast {0|1|2|3|4}
according to the sequence of 0 to 4
from dark to bright.
z TRIGGER COMMANDS
The power supply’s triggering system allows a change in voltage and
current when receiving a trigger, to select a trigger source, and to insert a
trigger. Triggering the power supply is a multi-step process.
z First, you must specify the source from which the power supply will
accept the trigger. The power supply will accept a bus (software)
trigger or an immediate trigger from the remote interface.
z Then, you can set the time delay between the detection of the trigger
on the specific trigger source and the start of any corresponding
output change.
Notice that the time delay is valid for only the bus trigger source.
z Finally, you must provide an INITiate command. If the IMMediate
source is selected, the selected output is set to the triggered level
immediately. But if the trigger source is the bus, the power supply is
set to the triggered level after receiving the Group Execute Trigger
(GET) or *TRG command.

TRIGger:SOURce?
Returns “BUS” or “IMM”.
TRIGger:DELay
Function:
Set or query the currently trigger delay.
