Speed for NuovaII

Hi,

 

I have a NuovaII (nonheated stirrer) from your company. On your site, it is stated that the stirrer has a speed from 100-1000rpm with 10 settings. Just wondering, if the scale on marked position is linearly distributed? Does it mean setting 1 is 100rpm, setting 4 is 400rpm and setting 10 is 1000rpm?

 

Kind regards,

Rachel
