RANG 

 
Purpose : 
Select the operating full scale current range. 
 
Command syntax : 
RANG{SP}{1|2}{;NL} 
 
Description : 
This  command  selects  the  full  scale  current  range  of  the  Electronic  load.  There  are  two 
full scale current range for each 3320 series Electronic load module. Table 4-3 shows the 
range I/II full scale current for each 3320 series load module. 
When RANG  command is excuted, the values  of the current level are adjusted as follow: 

 1.IF the existing current setting is within the new range. Then the current level does not 

change. 

 2.IF the existing current is setting in not within the new range. Then the current level 

is set to the  maximum of new range. 

The  maximum  load  current  level  is  shows  in  table  4-3.Table  4-3  maximum  full  scale 
current  level  for  each  module.When  the  programming  load  level  setting  is  greater  than 
the  maximum  current  level  of  each  range  of  each  module,  then  the  load  current  will 
adjust to the maximum current level which is listed in table 4-3.

RECALL 

 
Purpose : 
Recall the state of load level and load status which is stored by GPIB STORE command. 
 
Command syntax : 
RECALL{SP}{1|2|3}{;NL} 
 
Description : 
This  command  is  used  to  recall  the  non-volatile  memory  state  which  is  stored  into  the 
memory by GPIB store command, up to 5 states can  be recalled. 
 
Example : 
a.RECALL 1
