No. Item Name Description
————————————————————————————————————————
019 2 PREV PCOR CAL ZERO The previous value of item 018, updated on each PCor
Pressure Zero Calibration.
Default = 0.0000
020 PCOR CAL SPAN The most recent span value for the pressure transducer,
obtained during a PCor-Span calibration. The value is
normally very close to 1.0000 and is calculated on each
PCor Pressure Span Calibration.
Default = 1.0000
021 1 PREV PCOR CAL SPAN The previous value of item 020, updated on each PCor
Pressure Span Calibration.
Default = 1.0000
022 2 PREV PCOR CAL SPAN The previous value of item 021, updated on each PCor
Pressure Span Calibration.
Default = 1.0000
023 MIN PCAL PT DIF% The configurable spread or difference (expressed in percent of
full-scale of pressure range) required between PZERO and
PSPAN calibration points.
Default = 50.0000
024 XCESS PCAL CHNG% The configurable, maximum allowable change (expressed in
percent of full scale of pressure range) to PZERO and PSPAN
calibration points.
Default = 2.0000
025 PCOR TRANSDUCER RGE The upper range limit of the installed PCor pressure
transducer,
always expressed in PSI.
Default = 100.00
026 GAS TEMP Gas temperature measured at the last wake-up and used in
calculating the temperature correction factor (item 045). The
temperature value is scaled to the unit of measure selected at
item 089. If the instrument is set for fixed-factored
temperature item (111), item 026 should be manually set to the
average flowing temperature used in the supercompressibility
calculations, if super is active (item 110).
Default = 0.00
027 GAS TEMP LOLIM Low limit for temperature, initiates alarm (item 106 and 144) if
exceeded.
Default = -35.00
