PRS-300 Series
APPENDIX B
39
SOURce:RESistance <display value> Sets output resistance of the PRS-300 if table is set to 0 or
the resistance value corresponding to the display value for the table selected.
Display value is in the form of number and decimal point representing desired display value.
This is the same as SOURce:DATA command.
example SOURce:RES 0 would set display value to 0 and if Table is set to 1 to 4 this would rep-
resent the resistance value depending upon how the table is con fi gured. If in Celsius and PT-100 then
resistance of 100 Ω would be set at output of PRS-300.
CONFIGURE Commands
CONFIGURE:SELECT <2 or 4> Sets PRS-300 for 2 wire or 4 wire mode.
CONFIGURE:SELECT ? Returns number corresponding to 2 wire or 4 wire mode. 2 = 2 wire and
4 = 4 wire
CONFigure:TABLe:SELect <number> Selects Table to be used, <number> is 0 to 4. 0 is no table
with display shown in ohms and 1 , 2 and 3 are user de fi ned tables
CONFigure:TABLe:SELect? Returns table number that is selected
CONFigure:TABLe:NAME <name> Sets Table name, <name> is ASCII up to 20 characters such
as “PT100”
CONFigure:TABLe:NAME? Returns the number, 1 to 4 ,of currently selected table
CONFigure:TABLe:ERASE Erases all rows in the table
CONFigure:TABLe:ADD <user_value,resistance_value> Adds a row to the end of table showing
user value and resistance value in ohms.
example CONF:TABL:ADD 20, 95 means that if the table is selected and the operator enters 20
from the front panel the output will be set to 90 Ω .
CONFigure:TABLe:ADD? Returns the last entry in the table
CONFigure:TABLe:DISPlay? Returns all data in the table
Example of information returned
PT100
20, 95
CONFigure:TABLe:UNIT <Unit> Set units for tables up to 8 ASCII characters
As an example “C” could be send for Celsius or “F” for Fahrenheit
CONFigure:TABLe:UNIT? Returns ASCII string representing the units
CONFigure:SELECT <”2” or “4”> Sets “2” Wire or “4” Wire mode
