Value
Meaning
Any value not 0 int
Eror or warning code
Example
int i =
WrCalFileToStore
(0,
"C:\\SM60CAL.dat"
)
;
WrCalStoreToFile
Description
Transfer the contents of the on-board cal store to a file.
#include "SMU2060.h"
int WrCalStoreToFile (int
nDmm,
LPCSTR
lpszCal,
int
mode
)
Remarks
This function copies the calibration record stored in the on-board none volatile memory
of the DMM to the specified calibration file, pointed to by lpszCal. If
mode
is ‘a’ and a
file exists, the record is appended to the end of this file. If
mode
is ‘w’, a new file is
created, wiping out the old if it exists.
Parameter
Type/Description
nDmm
int
Identifies the DMM. DMMs are numbered starting with zero.
mode
int
Sets the file creation mode.
lpszCal
LPCSTR
Points to the name of the file containing the calibration
constants for the DMM. Calibration information is normally read
from the file named
SM60CAL.DAT
located in the C:\ root directory.
Return Value
Integer error code.

EraseCalStore
Description
Service function that wipes the Calibration record off the internal memory.
#include "SMU2060.h"
int
EraseCalStore(int
nDmm
)
Remarks
This function reformats the none volatile calibration store on-board the DMM, preparing
it for storing a calibration record. This function will remove the currently stored
calibration record and is not necessary during calibration.
Parameter
Type/Description
nDmm
int
Identifies the DMM. DMMs are numbered starting with zero.
Return Value
