VOLTage:STEP {<value>|DEFault} 
This order is used to service for VOLT UP and VOLT DOWN two orders. It can 
set the stepping value of voltage. Besides, VOLT:STEP? DEF order can inquire 
the stepping resolution of voltage of this unit. For example, the stepping setting 
value is 0.01, it represents 10mV. 
Order syntax: 
[SOURce:]VOLTage[:LEVel][:IMMediate]:STEP[:INCRement]  <NRf> 
Parameters: 
MIN~MAX 
*RST value: 
the stepping resolution of voltage of this unit 
Query order: 
VOLT:STEP? 
Return parameters: 
<NR2> 
VOLT:TRIG{<volts>|MINimum|MAXimum} 
This order is used to set a voltage to be triggered. At first, this voltage value is 
saved and only when receiving a trigger signal will the power supply output with 
this voltage value. Sending order VOLTage will not affect the setting value in 
this order. Sending query order, unit will return the previous setting value. If 
customer does not utilize order VOLT:TRIG at the beginning, then the return 
parameters will be the value you set with order CURRent . CURR:TRIG? MAX 
or CURR:TRIG? MIN orders will let you know the max and min voltage you can 
set.
