Read_ADcounts
SMU2060
SMU2064
Description
Read A/D offset counts.
#include "SMU2060.h"
int
Read_ADcounts(int
nDmm
)
Remarks
This function returnes the A/D raw counts. It is useful for retrieving the offset parameter
for various functions, including VDC, 2-W and 4-W ohms and DC current. It is limited
for service use.
Parameter Type/Description
nDmm
int
Identifies the DMM. DMMs are numbered starting with zero.
Return Value
Integer error code.
Value Meaning
Any value
int
Offset reading.
Example
int i = Read_ADcounts(0)
; // read offset parameter
WrCalFileToStore
SMU2060
SMU2064
Description
Transfer the contents of a cal file to the on-board cal store.
#include "SMU2060.h"
int WrCalFileToStore (int
nDmm,
LPCSTR
lpszCal
)
Remarks
This function copies the specified calibration file, pointed to by lpszCal, to the on-board
none volatile store of the DMM. This is appropriate following calibration operation. The
currently stored on-board record is replaced with the contents of the speified file. Make
sure that the calibration file only contains only one record, for the specified DMM.
Parameter Type/Description
nDmm
int
Identifies the DMM. DMMs are numbered starting with zero.
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.
Value Meaning
Any value not 0 int
Eror or warning code
