001 to an amount of flow using the square root
computation. Set the measurement 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

Description • You cannot use this command while recording
(memory sampling) or computation is in
progress. When using the /BT2 multi batch
option, you cannot use this command if any
of the batch groups is recording (memory
sampling).
• Set p1 and p3 by referring to the table in
section 3.3.
• For parameters p4 and p5, enter values with
five digits or less excluding the decimal point.
• For parameters p6, p7, and p8, either set all
three parameters or omit all three parameters.
