Multimeter Instrument Driver * LabWindows/CVI 5.0 Instrument Driver * Original Release: 3/4/98 * By: TKN, National Instruments, Austin Texas * PH. 800-433-3488 Fax 512-794-5678 * * Modification History: * * 3/4/1998 - Instrument Driver Created. * 7/7/1998 - [sz] Added VI_NULL entry to the error table in the * self_test function * - [sz] Changed the timeout in self_test from 20s to 1 min * - [sz] Changed attrRange_CheckCallback - deleted the * condition for the DIODE and CONTINUITY function * - [sz] Corrected the usage of checkErr and viCheckErr macros * - [sz] Changed IVIDMM_ERROR_ACCURACY* to FL45_ERROR_ACCURACY* * - [sz] Modified ?: operator parameters in * attrTriggerSource_WriteCallback * - [sz] Morphed 'if' to 'switch' statement in * attrTriggerDelay_WriteCallback and * attrTriggerDelay_ReadCallback functions * - [sz] Changed attrSecondaryFunction_WriteCallback function * (Reinstating the primary function will automatically * remove the secondary function.) * - [sz] Updated the minor version of the driver to 100 *****************************************************************************/#include <string.h>#include
