3) 2-coordinate file entry mode, where an actual X input signal is applied, and the
desired Y reading is provided from a file.
4) Equation entry mode, where the coefficients of a polynomial Y = K1X^P1 + K2X^P2 +
K3*X^P3 + … are entered. Up to 20 terms are allowed. An offset can be built into X.
You will be asked to supply the following:
LOW X-COORDINATE VALUE > (normally 0)
LOW INPUT MEASUREMENT VALUE > (normally 0)
HIGH X-COORDINATE VALUE > (normally 10,000 mV)
HIGH INPUT MEASUREMENT VALUE > (normally 50,000)
Position the decimal point from 6=.XXXXX, 5=X.XXX, 4=XX.XXX, 3=XXX.XX, 2=XXXX.X,
1=XXXXX. Specify the same position that you specified in the dEc.Pt decimal point menu
selection.
Follow the steps on the screens to finish generating the custom curve. When prompted to
download the file to the meter, select Y. When prompted to set the meter to custom curve
mode, also select Y.
KEYPAD CONTROL
You can take a meter in and out of custom curve linearization using the meter keypad.
From the Menu mode, press the > MENU key to get to ConFG, then set the fifth digit to either
0 (normal linear operation) or to 1 (custom curve operation).
FILES USED OR CREATED BY CURVE.EXE
1) *.RAW is the raw input file either supplied or created by one of the four data entry
methods.
2) *.DVD adds three columns from which the smoothness of the input data and obvious
input errors can be judged. The more data points and the smoother the data, the better
the curve fit.
3) *.NUM lists Y readings prior to custom curve linearization and addition of the decimal
point.
4) *.CCF is an internal file used by the software.
5) *.SIM lists simulated linearized meter readings and calculated corresponding errors.
6) *.PRM contains the final hex data that is downloaded into the meter.
