VOLTage {<voltage value>|MIN|MAX|UP|DOWN|DEF} 
This order is used to set the output voltage. No matter what the voltage range 
you select currently, the output voltage is subject to the newest setting value. 
Besides, MIN and MAX can be used as parameters.MIN represents 0V,MAX 
represents the max value of the voltage range. You may send VOLT? MIN or 
VOLT?  MAX  orders  to  quire  the  minimum  and  maximum  voltage  within  the 
range. DEF represents default value, it also can be used to set value. 
We can also send VOLT UP and VOLT DOWN orders to increase or decrease 
voltage, the stepping value should be set with order ” VOLTage:STEP”. 
Order syntax 
[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude] <NRf> 
Parameters 
MIN to MAX 
Unit 
V 
*RST value 
MIN 
Query syntax 
VOLTage? [MINimum|MAXimum] 
Return parameters 
<NR2> 
Example 
VOLT:STEP 0.01              //set the stepping value to be 0.01V 
VOLT UP                            //enable the output voltage increase one time 
VOLT:STEP 0.02              //set the stepping value to be0.02V 
VOLT DOWN                    //enable the output value decrease one time 
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.
