Command example
• Command Name
Defined using two alphabet characters.
• Parameter
• Command parameters.
• Set using alphabet characters or numerical values.
• Parameters are separated by delimiters (commas).
• When the parameter is a numerical value, the valid range varies depending on the
command.
• Spaces before and after of the parameter are ignored (except for parameters that
are specified using an ASCII character string (unit, tag, and message string), when
spaces are valid.)
• You can omit the parameters that do not need to be changed from their current
settings. However, delimiters cannot be omitted.
Example SR01,,2V<terminator>
If multiple parameters are omitted and delimiters occur at the end of the command,
those delimiters can be omitted.
Example SR01,VOLT,,,<terminator> → SR 01,VOLT<terminator>
• The number of digits of the parameters below is fixed. If the number of digits is not
correct when entering the command, a syntax error results.

YY/MM/DD (8 characters)
YY: Year (Enter the lower two digits of the year.)
MM: Month
DD: Day
• Time
HH:MM:SS (8 characters)
