 int plcXP89RdCalib( int chan,

struct _eioAdcCalib *pCalib )

Reads the calibration structure of a D/A channel from an XP8900

Series board.
PARAMETERS:

chan

is the channel number, 063, of the XP8900

Series D/A channel.

chan

8*board_ channel_number

_eioAdcCalib *pCalib

is a pointer to a calibration structure. Use

eioAdcDigitize

to compute the actual D/A output of a given analog

value.
RETURN VALUE: 0 if the operation is successful, otherwise returns a

negative number.
LIBRARY:

EZIOPBDV.LIB

 int eioAdcMakeCoeff( struct _eioAdcCalib *cnvrsn,

unsigned d1, unsigned d2, float f1, float f2 )

Takes the raw values and actual values of two data points, then com-

putes the calibration coefficients (assumes linearity).
PARAMETERS:

struct _eioAdcCalib *cnvrsn

is a pointer to a

calibration structure that stores the coefficients.

is the raw (quantized) value of the first data point.

is the raw (quantized) value of the second data point.

is the actual (real) value (in volts) of the first data point.

is the actual (real) value (in volts) of the second data point.

RETURN VALUE: 1 if it is not possible to compute the calibration

coefficients, otherwise 0.
LIBRARY:

EZIOPBDV.LIB

plcXP89RdCalib(32,&cinfo)

// read calib info of channel 0 of XP8900
// XP8900 Series board 4 into cinfo

eioAdcMakeCoeff(&cinfo,96,4000,9.97,-10.33)
