Description
Sets and queries current range use settings during range key operation,
auto-range operation, and auto-range integration as a value from 0 to 255
(data 1) or from 0 to 63.
Although NRf numerical values are accepted, values to the right of the
decimal are truncated.
Example
Command
:CURR:SEL 252,63
Configures the setting so that the 1 mA and 2 mA ranges are skipped
.
Query
:CURR:SEL?
Response
(When HEADER ON)
:CURRENT:SELECT 253, 63
(When HEADER OFF)
253, 63
Note
・
This command is provided to ensure compatibility with control programs for existing
models (3332).
To take maximum advantage of the PW3335
’
s functionality, it is recommended to use
commands such as :CURRent:SELect:I10A.
・
This command/query cannot be used to set or query external current sensor range use
settings.
・
This command cannot be used to set the 100 mA or 20 A ranges (which are always on).
・
Specifying a current range with the :CURRent:RANGe command will cause range select
for the specified range to be turned on.
・
You cannot change this setting during integration, while the display is held, or when the
maximum/minimum values are being held.
Set and Query External Current Sensor Input
Syntax
Command
:CURRent:TYPe <External Current Sensor Type>
Query
:CURRent:TYPe?
Response
<External current sensor type>
<External current sensor type> = OFF/TYPE1/TYPE2
Description
Command
Sets the external current sensor type.
Query
Returns the current sensor range setting as a string.
Example
Command
:CURR:TYPE TYPE1
Query
:CURR:TYPE?
Response
(When HEADER ON)
:CURRENT:TYPE TYPE1
(When HEADER OFF)
TYPE1
Note
・
After you change this setting, wait a few moments until the internal circuitry stabilizes
before you read any measurement values.
・
If the number of times to perform averaging is set to any value other than 1 and the range
is changed, averaging is restarted.
・
You cannot change this setting during integration, while the display is held, or when the
maximum/minimum values are being held.
・
If the instrument does not have external current sensor input, a hardware error will result.
