4.4 COMMANDS
4.4.1 PROGRAMMING MESSAGES
Some commands accept an optional suffix. This suffix can be used to specify the explicit Q-RPT
to address. In most cases, each Q-RPT in the RPM4 operates as an independent
measurement device. If the suffix is not specified, then the “Active” Q-RPT is assumed.
The “RANGE” or “ARANGE” command can be used to select the “Active” Q-RPT. There are
some limitations to use of the suffix when the RPM4 is in differential mode (see Section
3.3.3.1) or the “HL” Q-RPT is active (see Section 3.2.4). See the program message
descriptions for suffix use with a specific command.
