Also See: daqCalSetup,
daqCalConvert, daqCalSetupConvert
Format
daqReadCalFile (handle, calfile)
Purpose
daqReadCalFile is the initialization function for reading in the calibration constants from the calibration text
file.
Parameter Summary
Parameter Type Description
handle DaqHandleT Handle to the device which will be associated with the calibration file
calfile LPSTR File name with optional path information of the calibration file
Parameter Values
handle: obtained from the daqOpen function
calfile: a pointer to a string of characters; if the value of calfile is null or empty (“”), the default
calibration file DAQBOOK.CAL will be read.
Returns
DerrInvCalfile Error occurred while opening or reading calibration file
DerrNoError No error
For more details on error messages refer to the Daq Error Table.
Function Usage
The daqReadCalFile function (usually called once at the beginning of a program) will read all the calibration
constants from the specified file. The calfile parameter specifies the path\filename of the calibration file to read.
If calibration constants for a specific channel number and gain setting are not contained in the file, ideal calibration
constants will be used—essentially performing no calibration for that channel. If an error occurs while trying to
open the calibration file, ideal calibration constants will be used for all channels and a non-zero error code will be
returned by the daqReadCalFile function.
Prototypes
