Benyamin Rusanto I cannot help you with Labview but can provide some help on the 3458A. Several applications require two or more DMMs to make simultaneous readings. If you do not need the readings to be perfectly aligned you could use the NRDGS command to set up a block of readings and then use the TRIG command to start the block of readings on both DMMs. e.g NRDGS 10, TIMER would take 10 readings each would be spaced by TIMER. If each sample has to start at the same time then you could send an external trigger for each sample. e.g. NRDGS 10, EXT - would set up the DMM to take 10 readings, each reading requires an EXT trigger.
FYI ... In case anyone is wondering, that (INVOKE Clear) is the Clear command under the VISA menu tree,
Can you also execute BenchVue test sequences with LabVIEW?
Do you experrience with syncronize two dmm 3458a ?
