Detailed Description

EGU class for performing thermistor conversions.

Actual equation is: R = (C1 / Counts) + C0

Temp (deg C) = C2 * ln(R) + C3

Nominal C0 = - 1.020 E5 Nominal C1 = 4.096 E8

Fitted from (-40,80 degree) thermistor data from YSI. 30K ohm column (http://www.ysi.com/extranet/TEMPKL.nsf/447554deba0f52f2852569f500696b21/617d4fec8189026885256a03005d500a/$FILE/R_vs_T%20449XX.xls) Fitted C2 = - 20.319 Fitted C3 = 234.69

Member Function Documentation

__init__ (  coeff0  , coeff1  , coeff2  , coeff3  , units  = "" )

Initialize a raw/EGU conversion object. Parameters: coeff[0-3]  One of the coefficients of the function. See function doc units  The engineering units name, e.g. 'cm'

egu (  rawValue   )

Convert a value in raw units to engineering units Parameters: rawValue  Value in raw units Returns: Engineering units value after the conversion.

raw (  eguValue   )

Convert a value in engineering units to raw units Parameters: eguValue  Value in engineering units. Returns: Raw value after the conversion.
