p10 Low-cut function ON/OFF
p11 Low-cut point (0 to 50)
Query SR[ p1]?
Example Convert the DC voltage measured on channel
001 to a flow rate using the square root
computation. Set the input range to 6 V, the span
lower limit to 1 V, the span upper limit to 5 V, the
scaling lower limit to 10.0 m
3 /s, and the scaling
upper limit to 100.0 m 3 /s.

• Set parameters p1 and p3 according to the
table in section 4.3.
• For parameters p4 and p5, enter a value using
5 digits or less excluding the decimal point.
• Set all parameters p6, p7, and p8 or omit all
three parameters.
