PROGRAMMING MESSAGES
Some commands accept an optional suffix. This suffix can be used to specify the explicit Q-RPT
to address (HI, LO or HL). Only the HI or HL RPT can be the "active" Q-RPT at any time. If
the suffix is not specified, then the "Active" Q-RPT ("HI" or "HL") is assumed. The "LO" Q-
RPT cannot be made the "active" RPT, but you can access it's measurement using a suffix
of "2" in some commands. The "RANGE" command can be used to select the "Active" Q-
RPT. There are some limitations to use of the suffix when the RPM4-AD is in differential
mode (see Section 3.2.6) or the "HL" Q-RPT is active (see Section 3.2.5). See the program
message descriptions for suffix use with a specific command.
