GPIB Operation Description (Option)
: SOURce: SAFEty: STEP: IR: RANGe: UPPer?
This command queries the range is set.
Example: Input command “SAFE:STEP 3:IR:RANG?”
Return message “3.000000E-03”
Description: Return message “3.000000E-03” means setting range
of the main unit STEP 3 is 3mA.
:LOWer <numeric_value>
: SOURce: SAFEty: STEP: IR: RANGe: LOWer
This command is in accordance with users’ input current value to
select the range lower than the current can be measured.
Example: Input command “SAFE: STEP 3: IR: RANG: LOW
0.0003”
Description: This command means IR measured current value of the
main unit STEP 3 is set to 300uA. Thus, meanwhile
the selected IR range lower than the current can be
measured is 300uA.
:LOWer?
: SOURce: SAFEty: STEP: IR: RANGe: LOWer?
This command queries the range is set.
Example: Input command “SAFE: STEP 3: IR: RANG: LOW?”
Return message “3.000000E-04”
Description: Return message “3.000000E-04” means setting range
of the main unit STEP 3 is 300uA.
: AUTO <ON/OFF or boolean >
: SOURce: SAFEty: STEP: IR: RANGe: AUTO
This command sets if IR range switch to AUTO.
Parameter ON or 1 indicates AUTO on.
Parameter OFF or 0 indicates AUTO off.
Note
When users don’t set AUTO and give OFF parameter, it
will remain the previous setting range. When users set
AUTO and give OFF parameter then it will set to 10mA
range.
Example: Input command “SAFE: STEP 3: IR: RANG: AUTO ON”
Description: This command means IR measured current range of
the main unit STEP 3 is AUTO.
: AUTO?
: SOURce: SAFEty: STEP: IR: RANGe: AUTO?
This command queries if IR range switch to AUTO.
Return 1 indicates the setting is AUTO status.
Return 0 indicates the setting is AUTO status off.
Example: Input command “SAFE: STEP 3: IR: RANG: AUTO?”
Return message “1”
Description: Return message “1” means setting range of the main
unit STEP 3 is AUTO.
: CHANnel
[: HIGH] <channel_list>
: SOURce: SAFEty: STEP: IR: CHANnel: HIGH
5-29
