The (Calibrate...) and (Coeffs...) Commands
The
(Calibrate..)
and
(Coeffs..)
commands control zeroing, spanning, and
factory calibration coefficients. The
(Date
subcommand must be present, and
(Val
must be absent to perform
(ZeroH2O
and
(ZeroCO2
. For
(SpanCO2
and
(SpanH2O
,
(Date
and
(TDensity
must be present, and
(Val
must be absent to trigger a cal-
ibration.
Command
Subcommands
Remark
(Calibrate
(ZeroH2O
(ZeroCO2
(Val
{float})
)
)
For setting the zero directly. If not present
will trigger a calibration.
(Date
{quoted
string})
The date field triggers the instrument to do
a zero immediately. The new value will be
returned in an (Ack..) record.
(SpanCO2
(Span2CO2
(SpanH2O
(Span2H2O
(Val
{float})
)
For setting the span directly. If not present
will trigger a calibration.
(Target
{float})
Target value in ppm for CO
2
, or °C for H
2
O
(for reference purposes).
(TDensity
{float})
Target value in mmol m
-3
. (For
computational purposes).
(Date
{quoted
string})
(MaxRef
(CX {int})
)
Maximum expected value of raw reference
signal Aco at -40 °C.
(WX {int})
Maximum expected value of raw reference
signal Awo at -40 °C.
(Date
{quoted
string})
