DMMQuickInit
SMU2060  SMU2064 
Description Initialize a DMM without tests.
#include "SMU2060.h"
int DMMQuickInit(int nDmm, LPCSTR lpszCal)
Remarks It is not recommended to use this function for initialization since it is a short cut and does
not do all that is necessary for proper initialization. Use DMMInit instead. This function
or DMMInit() must be the first functions to be executed. It opens the driver for the
specified DMM. The first DMM being 0, the second 1, etc... It also initializes the DMM
hardware. This function is designed for speed and therefore does not perform the various
self tests and calibration performed by the DMMInit functions. It initializes the software
and reads the appropriate calibration record for the DMM from the file specified by
lpszCal. Depending on the operating system, the execution of this function can be under
100ms.
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 current directory.
Return Value The return value is one of the following constants.
Value
Meaning
DMM_OKAY
DMM initialized successfully.

Example /* initialize DMM */
int i = DMMQuickInit(0,"C:\SM60CAL.dat"); // Quickly initialize the first DMM
