Reading a query response
Only the query commands (commands that end with “?”) 
will instruct the power supply to send a response message. 
Queries return either output values or internal instrument 
settings. For example, the following statements executed 
from your computer will read the power supply’s error 
queue and print the most recent error:
Selecting a trigger source
The power supply will accept a bus (software) trigger or an 
immediate internal trigger as a trigger source. By default, 
the BUS trigger source is selected. If you want the power 
supply to use an immediate internal trigger, you must select 
IMMediate. For example, the following statements executed 
from your computer will set to an output of 3 V/1 A 
immediately:
dimension statement Dimension string array (80 
elements).
SYST:ERR? Read the error queue.
bus enter statement Enter the error string into the 
computer.
print statement Print the error string.
VOLT:TRIG 3.0 Set the triggered voltage level to 3.0 V.
CURR:TRIG 1.0 Set the triggered current level to 1.0 A.
TRIG:SOUR IMM Select the immediate trigger as a source.
INIT Cause the trigger system to initiate.
