Read the resistance of the active molbloc's PRTs in ohms.
"OHMS"
The most recent molbloc upstream and downstream PRT
resistance measurement is returned in ohms. An error will be
returned if there is a problem reading the molbloc PRTs.
Command:
"OHMS"
Reply:
"107.075 Ohms, 107.079 Ohms"
ERR# 42:
There is an error in the molbox RFM PRT
measurement.
3.2.5, "TEMP", "STDRES"
Read or set the user RPT calibration adjustments (PA, PM).
"PCAL=upadder, upmult, dnadder, dnmult, ( mradder, mrmult)"
"PCAL"
"PCAL=0, 1.00000, 0, 1.00000" (no microrange option)
"PCAL=0, 1.00000, 0, 1.00000, 0.0, 1.00000" (microrange option)
upadder:
The upstream RPT calibration adder (PA) from –
10 000 to 10 000 Pa.
upmult:
The upstream RPT calibration multiplier (PM) from
0.9 to 1.1.
dnadder:
The downstream RPT calibration adder from –10
000 to 10 000 Pa.
dnmult:
The downstream RPT calibration multiplier from
0.9 to 1.1
mradder:
The optional microrange RPT calibration adder
from -10 000 to 10 000 Pa.
mrmult:
The optional microrange RPT calibration multiplier
from 0.9 to 1.1.
The user defined pressure calibration for the upstream and
downstream RPTs can be access with this single command.
The adder is always in Pascal.
Command:
"PCAL=38, 1.0021, 14, .9942" (no microrange
option)
Reply:
"38 Paa, 1.00210, 14 Paa, 0.99420"
Command:
"PCAL=38, 1.0021, 14, .9942, 6, 1.0001"
(microrange option)
Reply:
"38 Paa, 1.00210, 14 Paa, 0.99420, 6.0 Paa,
1.0001"
ERR# 6:
Invalid argument.
