DMM incorrect voltage reading

[phywer]

Hi,

I am trying to read voltage with DMM and LabView.

I installed the driver for DMM and If I run one of examples, I get the correct  value ( -0, 000010V)

But If I run another script, the voltage is incorrect, it measures something between -1 and -6 V.

But if I do the same thing with another PC, this script works properly and measures the same value as example vi. So the script should be fine but why it doesn't work on different PC

I don't know if it is driver issue or something else or maybe just settings are wrong

Is there anything that I can try to understand and solve this problem?

Thanks

What DMM are you using?  What is the difference between the two PCs?  How are you communicating with the DMM (Ethernet, GPIB, RS-232, etc)?  What example are you using?

Thanks crossrulz. 

But I found out that the problem was localized decimal separator ", "  which is the difference betweend the two PCs.

for example:

Input= 5,123556 V => "Fract/Exp String To Number Function" => Output = 5,00000V

So I changed it and it is " . " now and it works.
