ARANGEn
Purpose
Read or set a new AutoRange range to use.
Command
Query
“ARANGE
n
Range, unit, mode (,RptLabel)
”
(set to user defined range)
“ARANGE Q-RPT
Label
”
(set to Q-RPT default range)
“ARANGE
n
?”
Classic
Query
“ARANGE
n
=
Range, units, mode (,RptLabel)
”
(set to user defined range)
“ARANGE=
Q-RPTLabel
”
(set to Q-RPT default range)
“ARANGE
n
”
Optional Suffix
“n”
A suffix may be used instead of “
RptLabel
”
‘1’ Specify the Hi Q-RPT
‘2’ Specify the Lo Q-RPT
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:
“G” for gauge
Arguments
RptLabel:
(optional)
One of the Q-RPTs that is available.
“IH”: Hi Q-RPT if the Hi and Lo Q-RPTs are NOT OFF. HL Q-RPT if
the Hi and Lo Q-RPTs are OFF.
“IL”: Lo Q-RPT
“HL”:
HL Q-RPT.
Remarks
The ARANGE command is used to define an RPM4-E-DWT range by specifying a
desired unit of measure, measurement mode and maximum pressure, and have the
RPM4-E-DWT pick the best available Q-RPT and make adjustments to optimize
operation in that range.
The optional suffix or the “
RptLabel
” argument can be used to specify which Q-RPT you
wish to use for the AutoRange range instead of allowing the RPM4-E-DWT to pick the
best Q-RPT. By using this option you can override the internal logic that picks the most
suitable Q- Q-RPT. This Q-RPT specified must be valid for the maximum pressure and
measurement mode specified.
The reply indicates the current range data, including the Q-RPT
Label
used for the range.
If “inWa” is specified for the unit, the temperature reference can be given after the unit
text (“inWa4”, “inWa20” or “inWa60” corresponding to inWa at 4 °C, 20 °C or 60 °F). If no
number is given, a default of 20 °C is assumed. There is no indication of the temperature
reference in the reply.
If you just specify the Q-RPT
Label
without any other arguments, the Q-RPT specified will
become active in it’s last range and settings. The previously set unit and measurement
mode for the Q-RPT specified will become active.
