ARANGE
Purpose
Read or set a new AutoRange range to use.
Command
Query
“ARANGE
Range, unit, mode (,RptLabel)
”
“ARANGE?”
Classic “ARANGE=
Range, units, mode (,RptLabel)
”
“ARANGE”
Range
The AutoRange maximum pressure. Cannot be negative.
Unit:
The unit of measure of the
Range
argument.
Mode:
The measurement mode of the
Range
argument:
“A” for absolute
“G” for gauge
Arguments
RptLabel:
(optional)
One of the Internal or External RPTs that are available.
“IH”:
Internal, Hi Q-RPT
“IL”:
Internal, Lo Q-RPT
“X1H”: First
external RPM4, Hi Q-RPT
“X1L”: First external RPM4, Lo Q-RPT
“X2H”: Second external RPM4, Hi Q-RPT
“X2L”: Second external RPM4, Lo Q-RPT
Remarks
The ARANGE command is used to define a PPCH-G range by specifying a desired unit of
measure, measurement mode and maximum pressure. The PPCH-G then picks the best
available Q-RPT and makes operational adjustments to optimize that range. Available
Q-RPTs may be determined by the use of the “RPT” command to search for external
RPM4 devices or use of the [RPT] function key.
The optional “
RptLabel
” argument can be used to specify which Q-RPT you wish to use
for the AutoRange range. By using this option you can override the PPCH-G internal logic
that picks the most suitable Q- RPT. The Q-RPT must have been previously found using
the “RPT” command or the [RPT] function key and must be valid for the maximum
pressure and measurement mode specified.
The reply indicates the current range data, including the
RptLabel
used for the range.

RPT previously found not detected. Usually occurs when the external
RPM4(s) have been disconnected since the last RPT “search”.
RPT previously found not the same as now found. Usually occurs when
the external RPM4(s) connections to the PPCH-G have been changed
since the last RPT “search”.

ATM
Purpose
Reads the next measured pressure from PPCH-G’s on-board barometer.
Query
Classic
“ATM?”
“ATM”
Remarks
The atmospheric pressure as measured by the PPCH-G on-board barometer is returned
in the current pressure units (always absolute). This measurement is followed by the
units text.
