Example
Convert the voltage measured with loop 1 to a
value in units of mV. Set the items as follows:
Range: 2 V, span lower limit: –2 V, span upper
limit: 2 V, scaling lower limit: –2000 mV, scaling
upper limit: 2000 mV, low-cut value: 0%

When p1 = 1 to 6 (When internal loop is specified)
When p2=PVrange
Syntax
CR p1,p2,p3,p4,p5,p6,p7,p8
p1: Loop number (1 to 6) (1 or 2 on the CX1000)
p2: Input type (PVrange)
p3: PV range lower limit (–30000 to 30000)
p4: PV range upper limit (–30000 to 30000)
P4-P3 ≤ 30000
p5: Decimal point position (0 to 4)
p6: Unit (up to 6 characters)
p7: Input switch PV lower limit (–30000 to
30000 loops)
within p3 and p4
p8: Input switch PV upper limit (–30000 to
30000 loops)
within p3 and p4
P8>P7
Note)
p7 is used only setting the
temperature range The meaning of
the parameter changes.
In other words, p8 becomes p7.
Query
