  • Page 4: Introduction

    1 Introduction If the [COMMAND MONITOR] function is used at the time of program creation, commands and responses will be conveniently displayed on the measurement screen. For information on the [COMMAND MONITOR] function, see the instruction manual of the instruments. Various messages are supported for controlling the instrument through the interfaces.
  • Page 5  Response Messages When a query message is received, its syntax is checked and a response message is generated. command determines whether headers are prefixed to response messages. :SYSTem:HEADer Header ON :RANGE 3.0000E-3 Header OFF 3.0000E-3 (The current measurement range is 3mΩ) At power-on, Header OFF is selected.
  • Page 6  Message Terminators This instrument recognizes the following message terminators (delimiters): • • CR+LF Also the terminator for response messages is as follows: • CR+LF  Separators (1) Message Unit Separator Multiple messages can be written in one line by separating them with semicolons “;” :FREQUENCY 1000;...
  • Page 7  Data Formats The instrument uses character data, decimal numeric data and character string data depending on the command. (1) Character Data Character data always begins with an alphabetic character, and subsequent characters may be either alphabetic or numeric. Character data is not case-sensitive, although response messages from the instrument are only upper case.
