●
C07
(PV1 cold junction compensation)
●
C17
(PV2 cold junction compensation)
• This is a selection for cold junction compensation for thermocouples.
• When set to 1, perform 0°C compensation using a cold junction compensation device
outside the DCP551
●
C08
(PV1 square root extraction)
●
C09
(PV1 square root extraction dropout)
●
C18
(PV2 square root extraction)
●
C19
(PV2 square root extraction dropout)
• Flow pressure detected by the orifice of a normal differential pressure type flowmeter
is proportional to the power 2 of the flow rate signal. Consequently, square root
extraction is used when a uniform signal is needed.
When the input in the square root extraction is
C09
or less than the dropout set in
C19
, an output of 0% can be obtained in the square root process.
• Square root extraction is not performed when
C08
and
C18
are set to 0.
●
C46
(auxiliary output 1 lower limit)
●
C47
(auxiliary output 1 upper limit)
●
C49
(auxiliary output 2 lower limit)
●
C50
(auxiliary output 2 upper limit)
• This is the scaling setting of the auxiliary output. The high and low values for the
upper and lower limits can be reversed.
• The example below shows that the output from auxiliary output 1 is 12mA when MV
is 100% and 20mA when MV is 0%. As shown, a 200% MV value is required to gen-
erate an output of 4mA.
Thus
C46
is set to 200.0 and
C47
is set to 0.0.
