Example Set the range mode of channel 10 to the
difference computation between channels with
the reference channel set to 01 and set the input
type to TC. Set the range to R. Set the span
lower limit to 10.0°C and span upper limit to
100.0°C.
SR10,DELTA,TC,R,100,1000,01
Description • This command cannot be specified while
measurement/computation is in progress or
while a report is being created.
• Set parameters p4, p5, and p6 according to
the table in section 6.3.
• For parameters p5 and p6, enter a value using
5 digits or less excluding the decimal point.
The decimal position is fixed to the position
indicated in the table in section 6.3.
