Fluke 5730A/03 Operator's Manual page 165

*PUD
Sequential command.
Description (Protected user data command.) Allows a string of bytes to be stored in nonvolatile
memory. The Calibrator secure state must be set to off. See the RPT_STR command.
#0 \<user data\> <ASCII Line Feed with EOI>
or
#<non-zero digit> \<digits\> \<user data\>
For both forms, the bytes received in the \<user data\> field are stored in nonvolatile
Parameter memory, allowing up to 63 bytes.
The first form accepts data bytes after the #0 until the ASCII Line Feed character is
received with an EOI signal. In the second form, the non-zero digit specifies the number
of characters (0 - 9, or ASCII 48 - 57 decimal), in the \<digits\> field. The value in the
\<digits\> field defines the number of user data bytes in the \<user data\> field.
*PUD #0FLUKE<Line Feed with EOI>
or
*PUD #15FLUKE
Both examples store the word FLUKE in the protected user data area.
Example:
*PUD?
Sequential command.
Description
Returns the contents of the *PUD (Protected User Data) memory.
Parameter None
#(non-zero digit) (digits) (user data)
The non-zero digit specifies the number of characters that will follow in the \<digits\>
Response
field. These characters are 0 through 9 (ASCII 48 through 57 decimal). The value of the
number in the \<digits\> field defines the number of user data bytes that follow in the
\<user data\> field. The maximum response is 64 characters.
*PUD?
Example
Returns: "205FLUKE" assuming that this is stored as in the example for PUD* above.
RANGE?
Sequential command.
Description
Returns the present output range.
Parameter None
Response (String) Symbolic name of the range from Table 5-4.
RANGELCK
Overlapped command, ignored if not in remote.
Description
Locks or unlocks the present output range. The range automatically unlocks if the output
function changes, for example from dc volts to dc current.
ON (Locks the range)
Parameter
OFF (Unlocks the range)
Table 6-5. Commands (cont.)
The 1 indicates that one digit must follow (in this case '5'),
and the 5 indicates that five characters are in the remainder
of the *PUD message (in this case, FLUKE).
