Parameters
The MultiRanger is pre-programmed for common PMD flow calculations. If your PMD is
not listed, select the appropriate Universal Flow Calculation.
Associated parameters Max Head (P603), Max Flow (P604), and Min Head (P605) may be
scroll accessed. If Operation is not set for OCM (P001 = 6), this value is preset to 0. If
Operation is set for OCM, it is preset to 1.
P601 Flow Exponent [MR 200]
The Exponent for the flow calculation formula.
Use this parameter if the Primary Measuring Device (P600) is set to 1 (exponential). It
creates an exponential curve with end points set by Max Head (P603) and Zero Head
(P604) and with the curve based on the specified exponent.
Use the exponent specified by the PMD manufacturer, if available, or the sample value
given below.

A Word on Exponents
The exponential equation is
Q = KH
P601
Where:
Q = flow
K = internal constant
H = head
