LabVIEW readings from a DMM too slow

[Taki1999 · Accepted solution]

Don't close your DMM session inside of the while loop. Close it at the end of execution. You probably don't want to be reconfiguring inside of the while loop either. Configure first and then run the trigger and read measurement inside of the loop. The natural delays from the instrument VIs probably make it unnecessary but it's good practice to include a wait inside of while loops so that CPU usage doesn't go haywire.

Thank You 🙂 I will try that

Hi Rach,

Did that work out for you, as I am having a similar issue with my DMM4020. The baud rate is set to 9600 which is supposed to be fast enough for simple data acquisition, and as you have mentioned the data rate of the unit is almost 100 samples/sec, but when you control it thru labview you end up waiting for 5-6 seconds which is really irritating !

So please advise whether the suggested solution have worked out for you.

Thanks in advance...
