write - read superfluous response NI-MAX Owon oscilloscope xds2102a

There is a problem:

when communicating with NI-MAX using SCPI commands I got response that cannot be automatically treated:

I do "write" NI-MAX via to the oscilloscope to measure cursor rms value: :MEASU:CH1:CURS?

Then I do "read" and the  the oscilloscope returns:

"CR : 510mV ->\n"

Me labview system cannot work with this format. It can deal only with the namber "510".

Anybody knows how to get rid off this superfluous "CR :" and "mV ->"?
