Read the last molbloc microrange transducer pressure.
"PR"
The last measured pressure from the optional microrange
differential pressure transducer is read in the current pressure
unit of measure. It is tare corrected. Depending on the molbloc
pressure, the microrange transducer may be bypassed. If it is
bypassed (both RPT inputs connected together to the upstream
pressure), then a '>' will appear in the reply to indicate that the
measurement does not represent the differential pressure across
the molbloc.
Command:
"PRDP"
Reply:
"10.5 kPa" (RPT is not bypassed - it is active)
Reply:
">10.5 kPa" (RPT is bypassed - it is inactive)
ERR# 23:
The microrange option is not installed.
3.1.2.6, "DP", "PR", "PRHI", "PRLO"
Read the last measured upstream absolute pressure (tare
corrected).
"PRHI"
The current upstream pressure value (corrected for tare) is
returned in the current pressure unit of measure.
Command:
"PRHI"
Reply:
"247.56 kPaa"
"DP", "PRDP", "PR", "PRLO"
Read the last measured downstream absolute pressure
(tare corrected).
"PRLO"
The current downstream pressure value (corrected for tare) is
returned in the current pressure unit of measure.
Command:
"PRLO"
Reply:
"224.67 kPaa"
